• Ubuntu crash problem, need fix

  - by Brad

  Upgraded to 12.04 LTS Beta 2, on a Dimension E310. The unity Sidebar crashes while I use Software Center. The only way I can close Software center Is to either power off my computer or use force quit app on the unity side bar. Thats why I believe it's the sidebar crashing instead of the software center. But the other problem is, apport don't recognize the bug so nothing is sent. How do I file this bug? I looked in VAR/Crash and there was no crash report.

• Looking for parallel programming problem

  - by Chris Lieb

  I am trying to come up with a problem that is easily solvable in a parallel manner and that requires communication between threads for a test. I also am trying to avoid problems that require require random waits, which rules out dining philosophers and producer-consumer (bounded buffer), two of the classics. My goal is for the student to be able to write the program in less than 20-30 minutes in front of a computer not knowing of the problem beforehand. (This is to prevent preparation more than to come up with something novel.) I am trying to stress the communication aspect of the program, though the multi-threaded nature is also important. Does anyone have some ideas? Edit: I'm using Google Go for the language and testing comprehension of the goroutines/channels combo vs an actors library that I authored.

• ssh login information

  - by bob

  As the admin of my machine, I want users to be able to log into my computer with ssh, but I'm looking for a graphical way to be notified that a user is connected at the moment. If multiple users are connected, I want a list of connected users, their location, name, etc. This could be in the form of a forceCommand and 'alert' command when someone logs in, plus a icon saying how many people are connected right now in the notification bar, with the option to click on it to have more information about these users. Is there such a tool available in ubuntu, and if not, how to do it (I'm guessing it's not that difficult and could be done with under ten bash command lines) ?

• Ubuntu installation always restarts

  - by user1880405

  I downloaded ubuntu-12.04.3-desktop-amd64.iso and mounted it to USB. I restart my laptop, select Install Linux and select language, then it says I have no internet, I press "Continue", and then I click "Install Ubuntu alongside Windows 8" and click "Continue", the computer just restarts and I see the again the same Try-Ubuntu-or-install-it menu. And hence I cannot install Ubuntu. I check md5 hash for iso and it's correct. Thanks for any help. P.S. I couldn't find answer anywhere else.

• How do I recover files from U1 cloud

  - by MarkWW

  OK I have just stopped syncing a folder. This appears to have been a huge mistake. I did not realise the folder would disappear from my cloud storage. I assume (and hope) the sub-folders/files it contained still exists in the cloud. I hope they still exists in the cloud because they do not exist on my computer. I did not delete these files from the cloud (I have tried to recover deleted files - none are being recovered). Where are they and how do I get them back into My storage?

• reading parameters and files on browser, looking how to execute on server

  - by jbcolmenares

  I have a site done in Rails, which uses javascript to load files and generate forms for the user to input certain information. Those files and parameters are then to be used in a fortran code on the server. When the UI was on the server (using Qt), I would create a parameters file and execute the fortran code using threads so I wouldn't block the computer. Now that is web-based, I need to make the server and browser talk. What's the procedure for that? where should I start looking? I'm already using rails + javascript. I need that extra tool to do the talking, and no idea where to start.

• Why does IDLE continue to crash? [migrated]

  - by Dyana

  Idle keeps crashing and I can't figure it out. After restarting the computer and reinstalling Python, none of which seemed to work, I looked to my peers and was told to "install one of the Tcl/Tk". After getting another opinion I was also told that I already had this and found it to be true but decided to try it anyway since it continued to crash. Nothing has improved and I have an assignment due. Any ideas on why this continues to happen and what I can do to fix the crash? Problem details: Process: Python [1183] Path: /Applications/Python 3.3/IDLE.app/Contents/MacOS/Python Identifier: org.python.IDLE Version: 3.3.0 (3.3.0) Code Type: X86-64 (Native) Parent Process: launchd [793] Date/Time: 2012-11-05 14:10:54.124 -0500 OS Version: Mac OS X 10.7.5 (11G63) Report Version: 9 Interval Since Last Report: 181805 sec Crashes Since Last Report: 4 Per-App Interval Since Last Report: 20 sec Per-App Crashes Since Last Report: 4 Anonymous UUID: 68994A08-7FFB-4074-A553-CB60A60BB412 Crashed Thread: 0 Dispatch queue: com.apple.main-thread Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Application Specific Information: * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Error (1007) creating CGSWindow on line 263'

• Keyboard activation bug

  - by Skydreamer

  I'm using Ubuntu's last version and there's still a little problem on my installation (already on previous versions). When I start the computer and reach the login screen, I have to wait about a minute to be able to begin to use my keyboard. That's not a real problem but that's kind of annoying. I've tried some things such as a lsusb via ssh and it worked and activated the keyboard without waiting. So I've tried to put it in the crontab (with @reboot) but it doesn't really work. Has someone got an idea how to solve this bug ? Thank you in advance.

• How to select which account is logged in at system startup, or none?

  - by hippietrail

  I'm helping out some friends with a tiny hospitality business where one desktop computer has some files used by the business in one account "hotel" but it's mostly used by guests for browsing the web in another account "guest". It's low security, we're not worried about hacking or anything. But we don't want people accidentally moving our files or anything either. But the system always boots into the "hotel" account without asking for a password, even though the account has a password. We want it to boot into the "guest" account. I know a bit about computers generally and Linux but not much about Ubuntu and the ever-changing graphical environment the Linuxes are going through these days. We've looked through the obvious settings/preferences/options and I've done some Googling. I know this should be obvious easy stuff but I can't find it. (We're running 10.04 LTS on a generic aging Intel box.)

• Encryption Password help!

  - by Carlos L.

  Ok so let me summarize this up. I encrypted my Home to protect against hackers of course when I first installed Ubuntu. It loaded up the Terminal and was attempting to show me my encryption password incase it ever needed to be used. So I thought "Ehh what the heck, I can find it out later..." So I closed Terminal and went on with the (amazing!) Ubuntu life. But now I am having to install Java JDK 7.0.0.4 onto my computer to ya know, play games and such. But it is asking for my password for the encrypted Home folder but it never gave it to me... HELP!!! Does anyone remember the command for Terminal to give you you're randomly generated Encryption password pop up on the famous purple window? Please give legitimate answer and fast please!

• Can't connect to wireless without typing sudo modprobe b43 in terminal

  - by user90889

  I just upgraded to 12.04 on an old ACER Travelmate 5320 using Broadcom 4311. I wasn't able to connect to the internet through the wireless for a few days. It didn't even display wireless networks. I was finally able to make it work by following the instructions found here: http://linuxwireless.org/en/users/Drivers/b43#supported However, each time I log on to the computer I have to go to the terminal and type sudo modprobe b43 to make the wireless work. Is there somehow I can avoid this? I have used Ubuntu for many years but always relied on other people to help me with the technical stuff. The terminal is alien to me so I literally follow online forum instructions without knowing what I'm doing. Also, I tried many many things before I managed to make it work. So I'm worried I may have installed something that now conflicts with whatever the sudo modprobe b43 does. Thank you

  - by user209270

  I recently installed Ubuntu (64 bit, 12.04) on a mid-2012 Macbook Pro, and I've been having some really annoying issues. Chief among them is that my wireless doesnt seem to function properly. I've installed Ubuntu on this mac before, and again this time the drivers for the wireless card were missing. I, using something along the lines of sudo su apt-get update apt-get upgrade apt-get b43-fwcutter firmware-b43-installer A new problem I've been experiencing however is that none of the networks available in my home show up. I've been able to connect theto themm by going into "Connect to hidden networks" and typing in the network name and password, but when I restart the computer my network (let's just name it "Network1"), doesnt show up. I tried going into "Edit Connections" and it shows up in the wireless tab, but it is never connected to automatically or shows up in the drop-down menu. Any help?

• Binfmt config not persisting after booting

  - by Ishpeck

  I have the binfmt kernel module set up so I can run .NET apps as if they were native binaries. I have the /etc/rc.local file configured identically to this. If I power down my computer or boot into Windows, when I come back to Ubuntu, I can't run .NET apps without calling Mono. However, if I simply touch /etc/rc.local and restart, the binfmt configuration appears to kick in and I can run my .NET EXE's as I expect to. How do I get my configuration to stick?

• Ubuntu 12.10 64 bit Slow

  - by Patrick Skiba

  I am new to linux and was wondering why launching applications is so slow. I've tried both Ubuntu 12.10 64 bit and Ubuntu 12.04 LTS 64 bit Computer Specs: Toshiba Satellite p755 CPU: Intel core i7-2670QM @2.20GHz Ram: 8 GB Using integrated intel hd 3000 graphics When I install the first thing I do is update, which takes about an hour or so. I would assume I'd be good after that, but when launching things like the firefox, system settings, thunderbird it takes a much much longer time than on Windows 7. Please help me.

• SPARC T5-4 Engineering Simulation Solution

  - by Mike Mulkey-Oracle

  A recent Oracle internal performance evaluation for computer-based product design demonstrated that Oracle's SPARC T5-4 server running MSC's SimManager simulation software with Oracle Database 12c consolidates the work of multiple x86 servers while delivering better overall performance.   Engineering simulation solutions have taken the center stage in helping companies design and develop innovative products while reducing physical prototyping costs, and exploring a larger design space, resulting in more design possibilities. For this solution, a single SPARC T5-4 server running Oracle Solaris 11 was deployed to consolidate the MSC SimManager server, the Oracle Database 12c server, and the web application server onto a single platform. An automotive design workload was deployed to demonstrate how the SPARC T5-4 server can be used to consolidate the work of multiple x86 servers and deliver better overall performance while reducing complexity and achieving optimal product designs.  A joint Oracle/MSC Software solution brief describes this in more detail:  A Simplified Solution for Product Lifecycle Management —MSC SimManager on a SPARC T5-4 Server

• How to make Bumblebee work with HP Pavilion DV6T-7000 Quad Edition with Intel HD 4000 and Nvidia GeForce GT 650M 2GB?

  - by user69469

  I just recently bought a HP DV6T-7000 Quad Edition. It has an Intel HD 4000 and a Nvidia GeForce GT 650M 2GB with Optimus. I read that I could use bumblebee to make optimus work, so I installed it. I also installed bumblebee-nvidia and nvidia-current from the ubuntu-x-swat/x-updates ppa. I rebooted, but when I tried to run anything with optirun, the computer would wait ten seconds or so, then do a hard shutdown. I got no log messages from bumblebee, Xorg, or optirun, either. I have purged and reinstalled bumblebee, bumblebee-nvidia, and nvidia-current. I have also set the turned off power management in the bumblebee.conf file to no avail. I am out of ideas about this, and I need both options. Any ideas would be much appreciated.

• Xubuntu and other Debian based distros slow

  - by William V

  I have a Compaq Presario SR1950NX desktop computer with the AMD64 3800+ processor and 1GB ram and it seems that Ubunutu, Xubuntu and Lubuntu are all laggy. Things seem to be slow such as clicking on menus and opening programs and the UI renders in peices. When using the browser the system slows down considerably. I ran the TOP command and I do notice that xorg hits 30 to 40 percent cpu when running the browsers. I have tried these distros on a spare P4 machine and it is even worse. As long as I don't have a several things open at one time I can manage to get around although sluggishly. I also notice that I can't get debian based distros to install in 64bit (crtc6 failure) only in 32bit. Can anyone tell me what is it that I might be doing wrong? I have an integrated Nvidia card and have tried several of the recommended drivers which sometimes result in no boot screen upon reboot. Thanks

• External monitor with NO mouse cursor

  - by Csaba Nyerges

  I am using a Fujitsu Siemens Amilo L7310 laptop computer with an external monitor. I'm wishihg to use version 10.04. The problem is, when I plug my laptop into the external monitor with my laptop screen turned either on or off, I do not see the mouse cursor on the external monitor! The mouse cursor is still there, although invisible. If I connect the external monitor to my laptop before swithing both on, the same happens. Is there any solution to make the cursor appear on the monitor?

• How to display time in the top panel?

  - by Mörre

  I thought I already had the time up there in the top bar, and it may have been so in previous Ubuntu versions (don't remember, my Ubuntu laptop is just one of three computers I use). Only that I just noticed - me being someone who never wears a watch, has the cellphone turned off 95% of the time and relying on the computer to tell the time - that there is no time being displayed anywhere, and I had expected it in the top bar on the Unity desktop. I searched around but found no obvious solution, but I'm sure someone immediately knows how I can get my time (back?) into the top bar?

• Managing a remote ubuntu server

  - by erdomester

  I hire an Ubuntu server which I access remotely and I purchased a domain for my webpage. I am totally new to this server thing and to Ubuntu as well. What applications should I install on the server? I need to transfer files to the server, I guess I would use FileZilla the same way I use it to upload files to my free website. But to have a username and password should I install an ftp server and create a user on Ubuntu? My website will send automated messages to users, so do I need to install a mail server as well? What other software should I install on the server apart from a firewall and an anti-virus? Should I partition the hard drive (3TB) and how? How partitions should I create and in what size for what applications? Btw I use Windows 7 on my computer, so I am basically a windows user.

• Ubuntu Software Center is crashing while trying to install psychonauts

  - by GonzoDark

  I am having a problem installing Tim Schafers epic platform video game Psychonauts trough the Ubuntu Software Center. I have bought the game on http://www.humblebundle.com/ and I have used the new redeem option introduced in this bundle: "redeem your bundle on the Ubuntu Software Center." When I have downloaded approximately 2.1 GB of Psychonauts then Ubuntu Software Center starts to repeatedly crash and pop-up with a new crash report dialog every few seconds (before previous ones are closed and that will crash the computer after a few min, unless I stop the download). I also have a file-size bug, where Ubuntu Software Center tells me that I have downloaded 880,2 MB out of 133,3 MB I use the new Ubuntu 12.04 LTS and Ubuntu Software Center version 5.2.2.2 (©2009-2011 Canonical <--- That is also a bug, should be 2012 I guess) I hope someone can help me.

• Cannot boot from Ubuntu Live CD on preinstalled Windows 8 laptop

  - by seferov

  I bought a Sony Vaio with Windows 8 yesterday. I want to install Ubuntu, (latest version), alongside Windows. There is an assist button on the laptop to enter the boot option menu, (otherwise, Windows 8 is booted by default. Whenever I choose the, 'boot from CD' option, it says 'No operating system found'. CD is valid since I tried it on another computer and it worked fine. I have tried both versions, 12.04 and 12.10. What is the problem, or how should I install Ubuntu on my laptop?
