• Installing Windows 7 from USB on a Thinkpad T61

  - by Halik

  I am trying to install Windows 7 Professional from USB 3.0 flashdrive, on a Thinkpad T61. The problem is, Thinkpads BIOS will not detect the flash drive as bootable medium, and won't allow to boot from it. What I did: Enabled USB BIOS Support in BIOS (it was on by default) In startup menu, added USB HDD to boot order (it has '-' sign in front of it) Created Windows 7 install media with UNetbootin, WinUSB (linux tool) dd and Grub4DOS. As you can tell, currently, I only have access to Linux machine to make the flashdrive. What happens: The T61 BIOS shows '-USB HDD' in boot order menu. The '-' sign suggests that the plugged flash drive is currently not bootable. The same flashdrive (with the same Windows image on it) is booting without any problems on a Dell D430 and Lenovo Y550. Also, Ubuntu 12.04 install USB created with Unetbootin shows as bootable ('+' sign in BIOS boot order menu) and boots from the F12 boot menu. Additional info thinkwiki.org says that some Thinkpad BIOSes do not use MBR on flashdrives. It suggests using Extended-IPL boot loader, but the provided links are broken and there seems to be no mirrors. Solution: http://superuser.com/a/430186/54970

• Mongrel Cluster on Ubuntu Server Karmic

  - by trobrock

  I am trying to get mongrel cluster working on my Ubuntu Server Karmic box in preparation to setup Capistrano. I've been trying to get the two to work all day and finally decided to completely remove Capistrano and see if I can just get Mongrel Cluster to work. I ran this to install mongrel cluster: gem install mongrel mongrel_cluster Everything installed fine, when I change into my app's directory... # mongrel_rails -bash: mongrel_rails: command not found I can run it from its install location: # /var/lib/gems/1.8/bin/mongrel_rails Usage: mongrel_rails <command> [options] Available commands are: ... It lets me build the cluster configuration file fine, but when I run the clister:start command: # /var/lib/gems/1.8/bin/mongrel_rails cluster::start starting port 8000 /usr/lib/ruby/1.8/rubygems/custom_require.rb:31: command not found: mongrel_rails start -d -e production -p 8000 -P tmp/pids/mongrel.8000.pid -l log/mongrel.8000.log starting port 8001 /usr/lib/ruby/1.8/rubygems/custom_require.rb:31: command not found: mongrel_rails start -d -e production -p 8001 -P tmp/pids/mongrel.8001.pid -l log/mongrel.8001.log starting port 8002 /usr/lib/ruby/1.8/rubygems/custom_require.rb:31: command not found: mongrel_rails start -d -e production -p 8002 -P tmp/pids/mongrel.8002.pid -l log/mongrel.8002.log It seems it isnt calling it from the right directory after that command, what can I do to fix this? I tried setting the path previously when trying to set up Capistrano, but the path didnt stay set when Capistrano used ssh to run the commands.

• Yum Error Installing Git from kernel.org Repo

  - by Lance

  I want to install the latest version of Git using yum and the RPM repository on kernel.org, but adding the repo to yum.repos.d causes yum to fail with checksum errors. The prevailing solution to this issue seems to be to simply use the repository at Webtatic as answered here on superuser. I know I can also install an older version of Git using the EPEL repo, or compile from the latest source tarball, but honestly I want to understand why I'm having issues using the kernel.org repo. Here’s the workflow, after a clean install of CentOS 5.5 and "yum update": [root]# wget -P /etc/yum.repos.d/ http://kernel.org/pub/software/scm/git/RPMS/git.repo [root]# yum clean all [root]# yum repolist Loaded plugins: fastestmirror Determining fastest mirrors * addons: mirrors.netdna.com * base: mirror.clarkson.edu * epel: serverbeach1.fedoraproject.org * extras: centos.mirror.nac.net * updates: mirror.cogentco.com addons | 951 B 00:00 addons/primary | 202 B 00:00 base | 2.1 kB 00:00 base/primary_db | 1.6 MB 00:01 epel | 3.7 kB 00:00 epel/primary_db | 2.8 MB 00:01 extras | 2.1 kB 00:00 extras/primary_db | 188 kB 00:00 git | 1.2 kB 00:00 git/primary | 155 kB 00:00 http://www.kernel.org/pub/software/scm/git/RPMS/i386/repodata/primary.xml.gz: [Errno -3] Error performing checksum Trying other mirror. git/primary | 155 kB 00:00 http://www.kernel.org/pub/software/scm/git/RPMS/i386/repodata/primary.xml.gz: [Errno -3] Error performing checksum Trying other mirror.

• Win7 Ultimate 64bit not finding my SSD, any ideas?

  - by Jakub

  So I am trying to install Windows 7 Ultimate 64bit on my new SSD (Kingston SNVP325-S2/64GB) and I have unplugged my other drives (for the install only). The SSD is detected by BIOS, I am running the latest Firmware for my motherboard P5N-E SLI (775 socket). Upon getting the Windows 7 install screen, it gives me a 'no drives detected'. I have tried Load Driver and downloding nForce drivers (latest for Win7 64bit signed WHQL) results in a message of (something like) "To continue please click Load Driver and load 32-bit and signed 64-bit drivers... blah blah" ... basically it does NOT accept my nForce SATA drivers, nor my 2ndary SATA drivers (JMicron? can't recall the exact name now). I have tried F8 at loading to 'disable driver signing' in hopes that it was an unsigned driver, however nothing works. The SSD is not detected by the Windos 7 installer. I wasted 4 hours on this last night, and gave up, and got nowhere. Anyone heard / ran into this issue before? How can I get the drive detected? Some more details: - Kingston SNVP325-S2/64GB V+ SSD - ASUS P5N-E SLI MOBO - 8GB RAM A-DATA (memory is checked out and fine)

• PC runs very slowly for no apparent reason

  - by GalacticCowboy

  I have a Dell Latitude D820 that I've owned for about 2.5 years. It is a Core 2 Duo T7200 2.0GHz, with 2 GB of RAM, an 80 GB hard drive and an NVidia Quadro 120M video card. The computer was purchased in late November of 2006 with XP Pro, and included a free upgrade to Vista Business. (Vista was available on MSDN but not yet via retail, so the Vista Business upgrades weren't shipped until March of '07.) Since we had an MSDN subscription at the time, I installed Vista Ultimate on it pretty much as soon as I got it. It ran happily until sometime in the spring of 2007 when Media Center (which I had never used except to watch DVDs) started throwing some kind of bizarre SQL (CE?) error. This error would pop up at random times just while using the computer. Furthermore, Media Center would no longer start. I never identified the cause of this error. I had the Vista Business upgrade by this time, so I nuked the machine, installed XP and all the drivers, and then the Vista Business upgrade. Again, it ran happily for a few months and then started behaving badly once again. Vista Business doesn't have Media Center, so this exhibited completely unrelated symptoms. For no apparent reason and at fairly random times, the machine would suddenly appear to freeze up or run very slowly. For example, launching a new application window (any app) might take 30-45 seconds to paint fully. However, Task Manager showed very low CPU load, memory, etc. I tried all the normal stuff (chkdsk, defrag, etc.) and ran several diagnostic programs to try to identify any problems, but none found anything. It eventually reached the point that the computer was all but unusable, so I nuked it again and installed XP. This time I decided to stick with XP instead of going to Vista. However, within the past couple of months it has started to exhibit the same symptoms in XP that I used to see in Vista. The computer is still under Dell warranty until December, but so far they aren't any help unless I can identify a specific problem. A friend (partner in a now-dead business) has an identical machine that was purchased at the same time. His machine exhibits none of these symptoms, which leads me to believe it is a hardware issue, but I can't figure out how to identify it. Any ideas? Utilities? Seen something similar? At this point I can't even identify any pattern to the behavior, but would be willing to run a "stress test"-style app for as long as a couple days if I had any hope that it would find something. EDIT July 17 I'm testing jerryjvl's answer regarding the video card, though I'm not sure it fully explains the symptoms yet. This morning I ran a video stress test. The test itself ran fine, but immediately afterward the PC started acting up again. I left ProcExp open and various system processes were consuming 50-60% of the CPU but with no apparent reason. For example, "services.exe" was eating about 40%, but the sum of its child processes wasn't higher than about 5%. I left it alone for several minutes to settle down, and then it was fine again. I used the "video card stability test" from firestone-group.com. Its output isn't very detailed, but it at least exercises the hardware pretty hard. EDIT July 22 Thanks for your excellent suggestions. Here is an update on what I have tried so far. Ran memtest86, SeaTools (Seagate), Hitachi drive fitness test, video card stability test (mentioned above). The video card test was the only one that seemed to produce any results, though it didn't occur during the actual test. I defragged the drive (again...) with JkDefrag I dropped the video card

• Postfix mail forwarder

  - by Andrew

  Hello, I just bought a dedicated server and I'm trying to install a webserver on it. The server is Ubuntu 10.04. I installed ftp, nginx, php, mysql, bind and now I have to install mail server. For the mail server I'm using Postfix, because it's recomended on ubuntu. I installed Postfix with apt-get install postfix but mail() function from php wasn't working. After a little debug I found the way to solve this : I created an empty file /etc/postfix/main.cf and it worked good. I do have a mx record like this mail 5M IN A xxx.xxx.xxx.xxx example.com. 5M IN MX 1 mail.example.com. After that I wanted to forward all e-mails to my GMail address. So I googled for it and I found in the official docs Virtual Domain Host Forwarding I added these lines in main.cf virtual_alias_domains = example.com virtual_alias_maps = hash:/etc/postfix/virtual I created map file and I placed this line in it @example.com [email protected] I run in terminal postmap /etc/postfix/virtual postfix reload The result: I can send e-mail from php with mail() function, but when I send an email to [email protected] that e-mail isn't forwarded to my Gmail. How to solve this? -Andrew I also tried this but not working http://rackerhacker.com/2006/12/26/postfix-virtual-mailboxes-forwarding-externally/ It works now! But I don't know what the problem was. I just installed "Mail Server" from Tasksel and after that it worked fine. Can anyone tell me what Tasksel installed or that it changed ?

• Errors in Homebrew on OS X Lion

  - by Bo Tian

  I just ran the Homebrew script as described in the installation page. I then ran brew doctor in Terminal, and it returned several errors. I'm not sure how to fix those errors, please help. brew doctor Error: Some directories in /usr/local/share/man aren't writable. This can happen if you "sudo make install" software that isn't managed by Homebrew. If a brew tries to add locale information to one of these directories, then the install will fail during the link step. You should probably `chown` them: /usr/local/share/man/de /usr/local/share/man/de/man1 Error: You have Xcode 4.2, which is outdated. Please install Xcode 4.3.

• OS X borked; need to backup outside of Time Machine

  - by rlbgator

  Quick Background: iMac G5 (the white one; 4 years old?) Running Leopard 10.5.something. Time Machine started failing on me; and every time I touch the Finder, things beachball like crazy. Booting from install disk then using Disk Utility to "Repair Disk" also fails. I'm left with the conclusion that I have a corrupt file somewhere important, that's (i) keeping TM from working and (ii) messing with basic functionality. I am not (yet) savvy enough in OS X to know what logs to look in, or how to decipher them - but 'corrupt file' seems to be the likely case, based on my readings of apple.com forum threads. So I think I need to backup, outside of Time Machine, then install fresh OS X on a new drive (or maybe SpinRite the current drive?). I'm able to put a (non-Time Machine) external USB drive on, so I dragged all 3 Users' folders to that... am I done backing up? Am I going to have a massive Permissions problem, trying to put things back together after a re-install? Thanks for reading.

• Failing Windows Updates with Error Code 800719e4

  - by Kev

  On a number of Vista machines I have now come across the same error - when installing updates everything works fine, until it after it reboots and the rolls back during step 3. On all occasions (where a simple retry hasn't worked) the error code has been 800719e4. On my own laptop I have so far tried the following:- Installed the updates one by one manually - I started on the smallest and one by one have worked towards the largest one which has left me with "Security Update for Windows (KB2286198)" that refuses to install. Renamed all the files in "C:\Windows\Logs\CBS" to "xxx.old" where xxx was the original name with windows update turned off - no change Renamed all the folders in "C:\Windows\SoftwareDistribution" in the same manner - no change Attempted to install it manually "Windows6.0-KB2286198-x86.msu" - no change Tried to un-install IE8 - doesn't work, rolls back at the end (Installing the IE9 Beta when it launched was what alerted me to the issue on this laptop) Ran a "Fix It" thing from the Microsoft Website - no help (Can't find the link now). Tried to recover from the disk - but alas my laptop only has a recovery partition (and was unservice packed original). Ran with nothing running on startup, and only MS services - again no change. Google is being useless with a load of posts trying to get me to call a telephone number with letters in (presumably an American number) The error code appears to mean error log full but no one has any idea which log! The WinUpdate log does indicate the following is the error point though :- 2010-10-23 13:54:48:230 1240 738 Handler WARNING: Got extended error: "POQ Operation SetKeyValue OperationData \Registry\machine\Schema\wcm://Microsoft-Windows-shell32?version=6.0.6002.18287&language=neutral&processorArchitecture=x86&publicKeyToken=31bf3856ad364e35&versionScope=nonSxS&scope=allUsers\metadata\elements\HKEY_CLASSES_ROOT_lnkfile_shellex_DropHandler_defaultValue, @default, , ewAwADAAMAAyADEANAAwADEALQAwADAAMAAwAC0AMAAwADAAMAAtAEMAMAAwADAALQAwADAAMAAwADAAMAAwADAAMAAwADQANgB9AAAA" Has anyone any idea how to fix this once and for all - reinstalling laptop after laptop from scratch is mildly annoying at work where Office and Firefox are the only extras, but even more annoying at home - I don't fancy going through the palaver of reinstalling everything yet again.

• Puppet&Hiera: $variable is not an hash or array when accessing it

  - by txworking

  I wrote a puppet module and the content of init.pp was: class install( $common_instanceconfig = hiera_hash('common_instanceconfig'), $common_instances = hiera('common_instances') ) { define instances { common { $title: name => $title, path => $common_instanceconfig[$title]['path'], version => $common_instanceconfig[$title]['version'], files => $common_instanceconfig[$title]['files'], pre => $common_instanceconfig[$title]['pre'], after => $common_instanceconfig[$title]['after'], properties => $common_instanceconfig[$title]['properties'], require => $common_instanceconfig[$title]['require'] , } } instances {$common_instances:} } And the hieradata file was: classes: - install common_instances: - common_instance_1 - common_instance_2 common_instanceconfig: common_instance_1 path : '/opt/common_instance_1' version : 1.0 files : software-1.bin pre : pre_install.sh after : after_install.sh properties: "properties" common_instance_2: path : '/opt/common_instance_2' version : 2.0 files : software-2.bin pre : pre_install.sh after : after_install.sh properties: "properties" I always got a error message When puppet agent run Error: common_instanceconfig String is not an hash or array when accessing it with common_instance_1 at /etc/puppet/modules/install/manifests/init.pp:16 on node puppet.agent1.tmp It seems $common_instances can be got correctly, but $commono_instanceconfig always be treated as a string. I used YAML.load_file to load the hieradata file, and got a correct hash object. Can anybody help?

• Monitor displays at 1024x768; scrolls screen for higher resolutions

  - by Matt

  I have a dual monitor setup. Normally, they both display at 1680x1050. They have been setup this way for about a year. I'm using Windows XP Professional 2003 x64 SP2. Today, out of nowhere, one of the monitors kicked back to a lower resolution. I was not playing with any configuration at the time.. in fact all I had done was close a window (maybe a browser). But the thing is that the resolution is still preserved partially by the fact that the screen will scroll when you move the mouse. So it's like looking through a 1024x768 window into a 1680x1050 world. The monitor itself does not appear to be damaged, because I also have it connected to my netbook (via KVM) and higher resolutions work fine. I tried uninstalling/reinstalling the drivers to no avail. System restore doesn't help either. I'm unsure of the exact ATI card I'm using.. Device Manager lists it as "Radeon X300/X550/X1050". There is no Catalyst Control Center software installed. I tried to install it, but there doesn't seem to be a way to install it by itself ... it forces you to install another driver, which breaks both of my displays, forcing me to go into safe mode and run system restore again. Any ideas? Thanks

• Missing MB on a GPT partioned SSD

  - by pisswillis

  I recently installed Arch Linux on an Intel 40GB SSD. I used GPT for partioning (via GNU parted) and created the following partions: /dev/sda1 : 1 MB, no FS, flag=bios_grub /dev/sda2 : 30MB, /boot, ext2, flag=boot /dev/sda3 : 20GB, /home, ext4 /dev/sda4 : ~20GB, /, ext4 After struggling to install grub2 from the livecd environment (which I finally did via grub-install /dev/sda --root-directory=/mnt/ --no-floppy --force) I got a working system. However, when I was inspecting disk usage with df I noticed that my home partition had around 170MB of used space on it. This surprised me because the only things on /home were one users .bashrc, .bash_history, and .lesshst. du confirmed that there was only a few KB of space being used on /home. Why does df report approximately 170MB being used when du does not? Is this space "gone forever", or can I regain it by repartioning and/or reinstalling? When I installed grub2 it said something along the lines of "your embed area is too small", and that I could "use BLOCKLISTS, but BLOCKLISTS are UNRELIABLE". In the end the only way I could get a system booting from the SSD was to use blocklists via the grub-install --force flag. Is this related to the mysterious missing 170MB? Thanks

• What is the 'best practice' for installing perl modules on Solaris/OpenSolaris?

  - by AndrewR

  I'm currently in the process of writing setup instructions for some software I've written that is implemented as a set of Perl modules. Having done this for various flavours of Linux, I'm now doing the same for Solaris/OpenSolaris (v10 only). Part of the setup process is to make sure that dependent Perl modules are installed. This has been pretty easy on Linux as the Perl modules I require tend to be within the distro's packaging system (eg yum install perl-Cache-Cache). This is not the case on Solaris so I'm working on setup instructions that use the CPAN module to fetch dependent modules (eg perl -MCPAN -e 'install Cache::Cache'). This works ok but there are known problems with modules that require things to be built with a C compiler. The problem is that the C Makefile generated assumes you're using Sun's compiler and uses command-line options not understood by gcc, which you may be using instead. Consulting teh Internetz has thrown up a number of solutions to this: Install and use Sun's compiler Use the perlgcc wrapper script Edit the makefiles by hand (yuk) All of these work. My question to those more familiar with Solaris than me is: Is one of these the 'best' or 'most commonly used' method?

• Edubuntu video playback and apt-get

  - by asdasd

  They had installed some modified edubuntu's at school... So i have some questions about setting some things up: How we can play HD videos ? They are made for windows machines and are in .wmv format but we need to play them on our multimedia class but don't know how - which player, which codecs etc. How to edit properly the /etc/apt/sources file ? Anything we try to install via apt-get it just says that E:\ is not available. Please tell me which repositories to put in there so we could be able to install some tools. Where are usually viruses/trojans put in ubuntu ? I mean in which directories ? Because our computers are behaving really slow and we need to check for some malware manually - we are not even allowed to install any kind of AV software. So tell me the usual directories and places for hiding such files, how are they hiddem, how to recognize them etc. Any others nice tricks/tips that we need to know. Thank you very much in advance.

• How can visiting a webpage infect your computer?

  - by Cybis

  My mother's computer recently became infected with some sort of rootkit. It began when she received an email from a close friend asking her to check out some sort of webpage. I never saw it, but my mother said it was just a blog of some sort, nothing interesting. A few days later, my mother signed in on the PayPal homepage. PayPal gave some sort of security notice which stated that to prevent fraud, they needed some additional personal information. Among some of the more normal information (name, address, etc.), they asked for her SSN and bank PIN! She refused to submit that information and complained to PayPal that they shouldn't ask for it. PayPal said they would never ask for such information and that it wasn't their webpage. There was no such "security notice" when she logged in from a different computer, only from hers. It wasn't a phishing attempt or redirection of some sort, IE clearly showed an SSL connection to https://www.paypal.com/ She remembered that strange email and asked her friend about it - the friend never sent it! Obviously, something on her computer was intercepting the PayPal homepage and that email was the only other strange thing to happen recently. She entrusted me to fix everything. I nuked the computer from orbit since it was the only way to be sure (i.e., reformatted her hard drive and did a clean install). That seemed to work fine. But that got me wondering... my mother didn't download and run anything. There were no weird ActiveX controls running (she's not computer illiterate and knows not to install them), and she only uses webmail (i.e., no Outlook vulnerability). When I think webpages, I think content presentation - JavaScript, HTML, and maybe some Flash. How could that possibly install and execute arbitrary software on your computer? It seems kinda weird/stupid that such vulnerabilities exist.

• Dell Driver Support for Latitude E6320 Windows 7 Enterprise

  - by IamPolaris

  I recently did a reinstall of Windows 7 Enterprise on a Dell Latitude E6320, which is a 64 bit system. After the install process, and doing typical Windows Update stuff, I looked at my Device Manager and found that I had devices which were missing drivers. My missing drivers: After going to the Dell Support site and looking at the files, and doing some sleuthing I found the following support document: http://downloads.dell.com/utility/Latitude%20E-Family%20%20Mobile%20Precision%20Re-Image%20How-To%20Guide%20-%20A03%20Rev%203%200.pdf This document hints in appendix C that the Broadcom USH is the Control Point Security and the Unknown device is Micro freefall sensor. The network controller is my wireless, as I cannot connect wirelessly, and the final missing driver I am not sure. Attempting to install the control point security exe on the support page will not work. After downloading, I am given the message that I am attempting to install a 32 bit driver on a 64 bit machine EVEN THOUGH I selected the win7 64 bit option from the support page. Beyond that, some of the drivers (Which are confusing to read and hard to understand what they do) and the system utilities which are supposedly supposed to make this process simpler will either a) not run because they are 32 bit exe's or b) the support page cannot find the file attempted to download. Is there anything I can do to get (at the very least) my wireless running, but idealistically all of my drivers. A solution which assumes Dell is completely incompetent would be ideal. :P Some forums have said that I should download the chipset driver, others say to get the system utility file (DSS_UTIL_WIN_R282536.EXE). I have had no luck as of yet...

• Virus cleanup; Windows Automatic Updates service crashes in esent.dll

  - by quack quixote

  Background I'm doing system recovery on an old WinXP SP1 system brought to me on suspicion of virus infection. After taking preliminary backups, I used MalwareBytes to detect and clean the infection. I might've even gotten it all. In the process, I've discovered (a) the system drive is showing signs of impending failure, and (b) the owner has been using the system's old crusty IE-6 instead of the up-to-date Firefox I've provided for him. So naturally, thinking I had a relatively stable system, I tried to hit the Windows Update site to install IE-8, in case further training doesn't stick. The update site told me it needed to update the installer, and I started that process. Soon after, wuauclt.exe started crashing, reporting addresses in module esent.dll. There's a Microsoft KB (910437) on a problem with that DLL, so I downloaded the hotfix and installed. The crashing did not stop. I attempted to install SP3 from the offline installer, but that didn't fix the issue either. The system is reporting a few hard drive / IDE controller errors, but they don't correlate to the crashes, so they aren't the direct cause. I've also attempted to rollback to the time between the infection removal and the first crashes, but that doesn't help. Question The hotfix I tried to install dealt with problem in transaction logs of the Extensible Storage Engine (ESE) database. I suspect this issue is similar, but that the database itself (whatever the ESE database is) is corrupted. Is there a way to clean or clear this database so that system operation returns to normal? Can someone enlighten me as to what the ESE database actually is, and where it resides? Can I just locate some files and delete them to bring this under control?

• Setting up xpra for client use in OS X

  - by Jonathan

  I've been trying to get xpra to run on OS X for the last few days to connect to my Ubuntu server. Note that there's a GUI for it called shifter, but that (at least on OS X) is still far too buggy. For those who don't know what xpra is, if you know what screen is, it's like screen for GUI X Windows apps tunneled over ssh. You can render a remote X app locally so it's faster than sending a series of compresses screen shots (like VNC), but with xpra you can disconnect and reconnect on different computers. To get the basic functionality you can just type "ssh -X server.location" and any GUI app you open from the command line will open locally. I've been able to get xpra to build by doing the following: Download pari-all-0.0.6.tar.gz from the xpra site listed under upstream and untar it. Issue the following Mac Ports command (Dependencies thanks to RogBlog): sudo port install python25 python26 py26-pyrex py26-gtk xorg-libXtst py25-gobject py25-gtk py25-nose py26-nose xorg-libXdamage xorg-libXcomposite xorg-libXtst xorg-libXfixes In the upstream list of v0.0.06 patches (NOT 0.0.8pre!) on the xpra site listed above, download mswindows-conditional-pyrex.patch. Open the patch with your favorite text editor and change the single occurrence of "win" in it to "darwin". Apply the patch to setup.py. Run do-build in the command line. Now where I'm stumped: how do I run xpra? The build produces a sub directory called install/bin in which xpra is located, but when I try to run it I get the following error: Traceback (most recent call last): File "./xpra", line 4, in import xpra.scripts.main ImportError: No module named xpra.scripts.main There is a file called main.py under xpra/scripts, but I don't know any python and I'm not sure if this is what it's looking for, and what to do with it even if it is. My goal is to set up xpra so I can install it into /usr/bin (or some other common path for executables) and execute it whenever I please. What do I do next?

• Windows is very slow with my new SSD

  - by Maksym H.

  I have a laptop HP probook 4520s with Core i5 M480 @ 2.67Ghz, 4Gb RAM, 640 GB HDD Radeon HD 6370m 1GB video card. It would seem like a good stack for work, right? But My HDD has crashed after everyday walking with laptop about 1 year. After buying my new SSD (Patriot memory - Torqx II 128 Gb SATA II) and installing new Windows 8 from scratch - it was amazing fast. But I had only install windows updates, and I feel that the speed become the same as my old HDD, after install other software for my work, it becomes so slow, so when I use my PC with old lower configuration and it really works better than my awesome laptop... I checked that TRIM and AHCI mode are turned on. So why's that? I asked for help in Patriot Memory support, they suggested to send them ATTO test results, done, sent. Here is the response: "Thank you very much for the attached results. Looking at the results, I can see that your SSD speed is a lot lower than it should be. Can you tell me your system specs?" Until they checked my email, I re-installed Windows 8 to Windows 7 and it was again perfect, but the story repeats it becomes slower and slower after every installing new software. Check out some screenshots.. (sorry for the screenshot with russian TaskManager, I hope you will recognize those parameters accordingly with your english or other lang TaskManager) So the main issue that something everytime loads the disc on 100% and the response time is jumping around 1000-3000 ms. Why am I asking about Windows? Because I tried to install Linux Mint (x86) and It just flies. So great performance independent on how many programs I have installed. Only Windows (any 7 or 8) has this problem. So guys, I appreciate any ideas about how to fix that and may be answers of main question - "why is it so.?" Thanks!

• How to share text, pictures and video to restricted set of users

  - by joaoc

  I want to share pictures and videos of my kid growing up but I don't want it to be open to the public. I just want me and my wife to be able to add material and then share with grandparents and friends who would be given a username/password or some other solution that authenticates them. This content would preferably be available remotely over the internet or downloaded periodically to the allowed viewers computers. The second option most likely means they would have to install a client, which I am not too fond of doing (I would have to ask them to install it, help configure for different platforms, ...) I'm at the start but I would like software that also allows export of the data (if one day I want to migrate to a different solution). Folder sharing I don't know if Windows folder sharing is reliable, robust and safe enough to share over the internet. Dropbox could be a software solution, but it's limited to 2GB and requires receivers to also install and configure software. A folder is just a collection of files, so it would be harder to keep them organized with text describing the pictures/video Email I could email the content every now and then but videos are almost always too big to go as attachments This would also not provide a history of updates to anyone just recently joining in Are there other solutions to achieve this? NOTE: I also thought that software to run a local or remote blog could be an option but we aren't allowed to ask those questions on superuser because one admin doesn't like cloud-computing questions. But if you do think it's the best approach and can suggest a solution, do state it in the answers anyway!

• ubuntu 9.10 installer doesn't recognize the hard drive

  - by dan

  I downloaded Ubuntu 9.10 x86_64 and am trying to install it on a fairly modern system with a Gigabyte GA-MA770-UD3 motherboard. Ubuntu 9.04 installed fine and still will when I stick that disc in, but 9.10 doesn't see my hard drive (western digital 250GB). If I boot from the disc, I can install gparted and it does recognize the drive, but when I try to start the install process from the live disc, Ubuntu again doesn't recognize the hard drive. I checked /var/log/messages and see this: Nov 12 17:28:08 ubuntu activate-dmraid: Serial ATA RAID disk(s) detected. If this was bad, boot with 'nodmraid'. Nov 12 17:28:08 ubuntu activate-dmraid: Enabling dmraid support Nov 12 17:28:08 ubuntu activate-dmraid: ERROR: either the required RAID set not found or more options required. Nov 12 17:28:08 ubuntu activate-dmraid: ERROR: either the required RAID set not found or more options required. Nov 12 17:28:08 ubuntu activate-dmraid: ERROR: either the required RAID set not found or more options required. Nov 12 17:28:08 ubuntu activate-dmraid: no raid sets and with names: "nvidia_ciiajheb-0" Nov 12 17:28:08 ubuntu activate-dmraid: ERROR: either the required RAID set not found or more options required. I checked my BIOS, SATA is enabled and is set to IDE mode, so there shouldn't be software RAID, but nonetheless, I added nodmraid to the boot line and tried again. It still doesn't recognize the drive. I checked /var/log/messages again and now see this: Nov 12 17:49:38 ubuntu activate-dmraid: Serial ATA RAID disk(s) detected. If this was boad, boot with 'nodmraid'. Nov 12 17:49:38 ubuntu activate-dmraid: Enabling dmraid support Nov 12 17:49:38 ubuntu activate-dmraid: WARNING: dmraid disabled by boot option Nov 12 17:49:38 ubuntu activate-dmraid: WARNING: dmraid disabled by boot option Any ideas on things to try? I've tried all of the various BIOS settings for SATA. IDE,RAID, etc. Nothing seems to work.
