  • External USB hard-drive changing drive letter

  • Music Manager thst can properly synch song ratings with Android

    - by Sebastian
    I'm moving from Windows 7 to Ubuntu, and so far the experience has been a really good one :) However, there is something that I've used to do with Windows 7 that I can't find how to do in Ubuntu: From my Windows music manager programs (either MediaMonkey or Windows Media Player) I could set song ratings in a way that the ratings set from either program could be also read from the other one. Additionally, song ratings were visible and updated in my iPod Touch when I synch'ed my music (either manually or using iTunes). To sum up, it seems that MediaMonkey, WMP, and the iPod device use standard mp3 metadata tag for ratings. Now, using Ubuntu 12.04, and now with an Android device: Rhythmbox can't see the song rates, despite those ratings can be seen by MediaMonkey and MS Music Player when I boot with Win7. Is this an issue I can fix with some setting? Is there any program I can use to accomplish this? What do you recommend to sync my music with Android (4.0, Galaxy s2), also keeping the song ratings information updated between Android and my PC? Thanks!!

    - by Jason Fitzpatrick
    Tonight is the peak of the Geminid Meteor shower, if you don’t mind braving the cold and have a spot relatively free from light pollution to stretch out in you’ll be able to enjoy one of the more brilliant and busy meteor showers of the year. Sky and Telescope magazine reports on the Geminid Meteor shower: If it’s clear late Thursday night, December 13th, 2012, keep a lookout high overhead for the shooting stars of the Geminid meteor shower. The Geminids are usually one of the two best meteor showers of the year, often beating out the Perseids of August. And this year there’s no moonlight to interfere. Under a clear, dark sky, you may see at least one Geminid per minute on average from roughly 10 p.m. Thursday until dawn Friday morning. If you live under the artificial skyglow of light pollution your numbers will be less, but the brightest meteors will still shine through.

  • Host grub error after installing Virtualbox - Non Recoverable

    - by BiggJJ
    I have been unable to fine a resolution to my problem and I have been suffering from it for a while. I can install Virtualbox and can reboot the machine successfully straight after. Once the system is back up I can run Virtualbox ans start working towards creating a new machine. So, say I am installing an XP machine. 1 time out of 10 it will work successfully first time. If it doesn't work (i.e BSOD), I delete the machine and start again. But when the time comes to finish up and switch off my computer, but it doesn't happen gracefully. As soon as I click shutdown, The machine dies. When the machine is switched back on I get: Error: no such device grub resuce I boot up my Grub Fix Live CD, but the grub reinstaller get stuck on searching for partitions, gparted just get stuck looking for devices and even fdisk -l drops a line and displays nothing and is the same. Stuck. The only way I know how to sort it is by re-installing Ubuntu. Has anyone had this problem, or know how to fix it?

  • Unable to start lightdm but can startx

    - by wzyboy
    I am trying to make my own Live USB and I have successfully generated an ISO file with a newly installed, configured and customized Xubuntu 12.04 LTS installation. My problem is that, no matter I boot the ISO in VirtualBox or in GRUB with loopback, it just cannot start the lightdm. When booting, I can see the log messages on the screen, it stucks at Stopping System V compablities or Configuring Network security. And tty7 is frozen... If I switch to tty1, I can get a logged-in shell as ubuntu@ubuntu. The weird thing is: When I type sudo start lightdm or just sudo lightdm, it will switch to tty7 and the screen flashes. Then nothing happened. Return to tty1 and I can see lightdm running, process xxxx. But the process does not exist. It was just crashed immediately I think. (That's why the screen flashes.) However, when I type startx, I can get into the desktop! That's amazing for me. I am not very clear about the relationship between X Server and Display Manager, but I think lightdm is running when I see the desktop! Then, what's wrong with sudo start lightdm? I use this command every time I power on my laptop since I have a text parameter added in grub.cfg. It never "crashed immediately". I need to use sudo start lightdm because it gets me into "Xubuntu Session" instead of "Xfce Session", the prior is more beautiful... Could anyone help?

  • How do I create an encrypted file system inside a file?

    - by darent
    Recently i've found this interesting tutorial: http://flossstuff.wordpress.com/2011/08/07/using-a-file-as-a-storage-device/ It explains how to create an empty file, format it as ext4, and mount it as a device. I'd like to know if it can be created as an encrypted ext4 file system. I've tried using palimpsest (the disk utility found in System menu) to format the already created file system but it doesn't works as it detects the file system being used. If I try to unmount the file system, it won't work neither because it doesn't detect the device (since it's not a real device like a hardrive or a usb drive). So my question is, is there an option to create the file system encrypted from the begining? I've used these commands: Create an empty file 200Mb size: dd if=/dev/zero of=/path/to/file bs=1M count=200 Make it ext4: mkfs -t ext4 file Mount it in a folder inside my home: sudo mount -o loop file /path/to/mount_point Is there any way the mkfs command creates the ext4 encrypted asking for a decryption password? I'm planing to use this as a way to encrypt files inside Dropbox. Thanks for your time.

  • Dark screen when wake / Unable to control screen brightness

    - by John
    Running Ubuntu 11.04 on Lenovo ThinkPad with an Nvida graphics card. The unit goes to sleep when the lid is shut. (The unit goes to suspend mode (not to disk/hibernate), AC gets turned off, running on battery) Upon lid-open sometimes the screen is almost too dark to read. I'm really not sure of the exact cause, (very low batt??). The only fix is a reboot. The screen brightness buttons have never worked in Ubuntu. I have messed w/ the power management preferences. No change. At one point I messed w/ the gnome settings. No change. I have tried a few cmds: echo 9>/sys/class/backlight/acpi_video0/brightness setpci -s 00:02.0 F4.B=10 xgamma -gamma .75 None of these help. Most have zero effect. I think it is and acpi thing, but that is just a guess. I'm out of idea's, and looking for suggestions. Thanks

  • Oracle Linux 6 update 3

    - by wcoekaer
    Oracle Linux 6.3 channels are now available online http://public-yum.oracle.com repositories. Both base channels and latest channels are available (for free for everyone) http://linux.oracle.com repositories. Behind our customer portal but effectively the same content. Source RPMs (.srpm) are being uploaded to http://oss.oracle.com/ol6/SRPMS-updates. OL6.3 contains UEK2 kernel-uek-2.6.39-200.24.1. The source rpm is in the above location but our public GIT repository will be synced up shortly as well at https://oss.oracle.com/git/?p=linux-uek-2.6.39.git;a=summary. Unlike some others, of course, complete source, complete changelog, complete checkin history, both mainline and our own available. No need to go assemble things from a website manually. Another cool thing coming up is a boot iso for OL6.3 that boots up uek (2.6.39-200.24.1) as install kernel and uses btrfs as the default filesystem for installation. So latest and greatest direct access to btrfs, a modern well-tested, current kernel, freely available. Enjoy. Since it takes a few days for our ISOs to be on http://edelivery.oracle.com/linux, I mirrored them on my own server :http://mirrors.wimmekes.net/pub/OracleLinux/

  • Dell xps 15z fan issue in ubuntu 12.04

    - by Paxinum
    I just updated to ubuntu 12.04 on my Dell laptop xps 15z. The trouble is that I hear a slight ticking sound every 3rd second, probably from a fan. This is a new issue in this ubuntu version. I use the recommended boot options for grub, i.e. acpi_backlight=vendor, but I do not use any acpi=off or acpi=noirq. Is there a way to fix this issue from ubuntu, by maybe controlling the fans somehow? EDIT: Notice, the sound goes away as the fan speeds up, (when doing calculations or such), so it is really a fan issue. EDIT2: I have located the issue: If I use conky 1.9, together with the command execpi for a python application, then the sound appears, and the noise syncs with the update interval for conky (NOT for the update interval for execpi!). The noise seems to be proportional to the complexity of the drawing that is needed. This is very strange, as this issue was not in the prev. version of conky I used. The solution was to increase the update interval for conky from 0.5 to 3, i.e. update every 3rd second instead of twice a second.

  • Ubuntu 11.10 power management does not recognize removal of power supply!

    - by sema
    I have a Lenovo Ideapad Z370 with Ubuntu 11.10 and the battery status indicator shows wrong information. Problem: The indicator always shows that the power supply is connected, even if it's not connected. The battery charges and discharges normally. However, the status information is wrong. When charging, the "time to charge" decreases, and when discharging the "time to charge" increases. If the power supply is connected the power statistics show: "Supply Yes" "Online Yes" If it is not connected it shows: "Supply Yes" "Online No" My trials: I tried reinstalling the indicator applet, but that doesn't help. Searching for solutions or similar problems didn't point out any help. Background: The problem occured after I switched the battery mode in Windows. (I use a dual boot system.) Lenovo drivers allow a "battery runtime mode" for maximum runtime and a "battery health mode" for maximum battery lifetime. I initially used the runtime mode, tried the health mode for some time, but switched back to the runtime mode. The problem occured after switching to health mode. Does anyone have an idea what is wrong? The problem is relevant for me as I get no information when battery status low and the computer runs out of energy without shutdown or hibernation. This is really a problem for me!

  • Search SSIS packages for table/column references

    - by Nigel Rivett
    A lot of companies now use TFS or some other system and keep all their packages in a single project. This means that a copy of all the packages will end up on your local disk. There is major failing with SSIS that it is sometimes quite difficult to find what a package is actually doing, what it accesses and what it affects. This is a simple dos script which will search through all packages in a folder for a string and write the names of found packages to an output file. Just copy the text to a .bat file (I use aaSearch.bat) in the folder with all the package scripts Change the output filename (twice), change the find string value and run it in a dos window. It works on any text file type so you can also search store procedure scripts – but there are easier ways of doing that. echo. > aaSearch_factSales.txt for /f “delims=” %%a in (‘dir /B /s *.dtsx’) do call :subr “%%a” goto:EOF :subr findstr “factSales” %1 if %ERRORLEVEL% NEQ 1 echo %1 >> aaSearch_factSales.txt goto:EOF

  • What partition to use to keep data files in Ubuntu?

    - by Martin Lee
    I have been using Ubuntu for a few years and usually my partition set up was the following: Ext3 or Ext4 partition for the system itself (20 GB); A 10 GB swap partition; a big FAT32 partition to store movies, photos, work stuff, etc. (depends on the capacity of the disk, but usually it is what is left from Ext3+Swap, currently it is more than 200 GB). Does this setup sound right? I am considering to switching to one big Ext3 partition now, because the problem with Fat32 in Ubuntu has not gone anywhere: for example, right now I can access my 'big' partition with a 'Data' label only through /media/_themes?END. Pretty strange name for a partition, isn't it? some Linux software fail to read/write on this partition. For example, if I want to play around with rebar and build/make/compile things on this FAT32 partition, it will always complain about permissions and won't work (the same goes for many other kinds of software); it is not stable, I can not refer to some files on this FAT32 partition, because after the next reboot it will be called not '_themes?END', but something else. On the other side I usually begin to run out of space on the Ext3 partition after a few months of usage. So, the question is - what is the best setup of partitions for an Ubuntu system? Should a FAT32 partition be used at all?

  • Trouble installing Pokerstars on a Live USB without Persistence through WINE

    - by Ricky Foster
    I need to install any form of Texas Hold Em' on a Lubuntu Live USB that doesn't have persistence. I was able to download PokerStars.net by emulating the .exe (a windows type file) using WINE for Linux (Lubuntu). But, when I try to install, I have no room. The only place on the Live USB is in the root folder which is set to read-only. Is there any way I can change the read only properties of the Live USB while it's in use? So, to recap. I am running Lubuntu 13.04 and can't start in Persistent mode. When I start normally everything worked fine. I proceeded to Chromium and successfully downloaded Wine and the Pokerstars.exe. I right clicked the downloaded fiel then clicked Wine, the installer loaded fine. There are about 8 different disk icons and only the one containing system files is active. Is there any way I can use the terminal to install it to Root. Thanks in advance for your answer/alternate method (without having to buy another USB to install it to).

  • How to make pulseaudio and ubuntu detect the same audio device as alsa driver

    - by Kiwy
    I use Ubuntu 14.04 x64 and I use gnome-shell on my laptop. I have a Bose companion 5 (which is basically a USB sound system) and a HDMI port, both does work perfectly when I just boot with the cable plugin. However, when my laptop go to sleep or get unplugged from those two outputs, if I plug back the device, I end up without any hardware detection (only the built-in speakers) from pulse and gnome-shell sound output selector while if I use alsamixer, the device look up and ready. gstreamer-properties allow me to select and test effectively any device but while alsa recognize any device on the run, pulse is not capable of handling things correctly, my question is then: How can I make pulse detect and use the same hardware as alsa, or how to remove completely and gracefully pulseaudio (meaning volume applet running in gnome shell) I don't mind if the project implies to recompile half gnome shell if it implies those audio outputs work all the time. Pulse does not list my soundcard when I use command pactl list cards while the module plug&play for sound card is loaded in pactl list modules. I really don't know what to do, the behavior seems pretty random.

  • Laggy Graphics After Upgrade to Ubuntu 13.10

    - by John bracciano
    I noticed some issues concerning the graphics after I upgraded from Ubuntu 13.04 to 13.10. More specifically: Dash tends to be more "laggy" than it used to be. When I switch desktops you can clearly see the screen going frame by frame. Menu bar is also "laggy". When I open GIMP, the menu bar is useless after a while - it takes seconds to refresh. The problems seem to appear after some seconds of use. When I boot the system everything works fine, until some more graphics-intensive program starts (Firefox, GIMP, etc). /usr/lib/nux/unity_support_test -p reports: OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Mobile OpenGL version string: 3.0 Mesa 9.2.1 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes I use an Asus Zenbook UX31A with: Intel® Core i5 Ivy Bridge Integrated Intel® HD Graphics 4000 Intel® HM76 Express Chipset Thank you in advance for any answer!

  • Cannot restart Ubuntu after replacing Unity with Gnome and purging lightdm

    - by OtagoHarbour
    I am running Ubuntu 11.10. I used the directions here to replace Unity with Gnome. It seemed to work fine until the end of step 2 when I rebooted the computer. When I chose the default option, I just got a black screen. When I choose the restore option and then "Restore normal boot" I get Starting load fallback graphics devices [fail] Starting GNOME Display Manager [ok] Starting Userspace bootsplash [ok] Stopping GNOME Display Manager [ok] Stopping Userspace bootsplash [ok] Starting web server apach22 [fail] (among a lot of OKs) It finally gets to Stopping System V runlevel compatibility [ok] where it hangs. I left it overnight and just had a blank screen when I checked it in the morning. I can "Drop to root shell prompt" and "Drop to root shell prompt with networking". I did see here that one should be able to fix the problem by choosing remount and then doing apt-get install lightdm I tried this as root shell with and without networking and got the message Err http://us.archive.ubuntu.com/ubuntu/ oneric-updates/main lightdm i386 1.0.6-0ubuntu1.7 Could not resolve 'us.archive.ubuntu.com/ubuntu' What is the best way to resolve this problem?

  • Ten Classic Electronic Toys and Their Modern Equivalents

    - by Jason Fitzpatrick
    Whether you’re looking to relive the toy exploits of your youth or pass your love of tinkering and electronics onto the younger generation, this list highlights ten great electronic toys of yesteryear and their modern equivalents. Courtesy of Wired’s Geek Dad, the description for the all-in-one electronics kit seen here: What is was: Arthur C. Clarke has said that any sufficiently advanced technology is indistinguishable from magic. As a kid in the midst of an increasing technological revolution, electronics were at the heart of that. Learning electronics was made easy through the Science Fair Electronic Project Kits found at Radioshack. Through the project guides, kids could construct various ‘experiments’ by attaching wires to terminal springs that make circuits. The terminal springs would wire in components such as LED segment lights, photo sensors, resistors, diodes, etc. While it was fun getting the projects to work, the manuals lacked in depth explanation as to what was happening in the circuit to produce the project’s result. Why it was awesome: First, it was a simple buy for parents. Everything you needed to get your child interested in electronics was right in the kit. You didn’t need to breadboard or solder. I remember a distinct feeling of accomplishment making a high-water alarm or a light-sensor game with the realization that the bundles of wires springing up from the kit were actually doing something! Modern equivalent: You can still pick up variations of the 100-in-1 kits, but their popular replacement seem to be Snap Circuits by Elenco. All of the components are mounted on a plastic base with a contact on either end which interconnect with each other and the plastic base that projects can be mounted to. Each component also has the electrical diagram symbol for that component drawn on it so it can help you read schematics. For that reason alone, I like these better.

So i uncheck: Added by software-center; credentials stored in /etc/apt/auth.conf https://private-ppa.launchpad.net/commercial-ppa-uploaders/xojo/ubuntu GPG error was gone. But then again I found myself at the beginning of the problem.STUCK at '0% [Working]'. 'Xojo' is the only application that I can't install.Any explanation why is it like that?

  • What features are helpful when performing remote debugging / diagnostics?

    - by Pemdas
    Obviously, the easiest way to solve a bug is to be able to reproduce it in-house. However, sometimes that is not practical. For starters, users are often not very good at providing you with useful information. Customer Service: "what seems to be the issue?" User: "It crashed!" To further compound that, sometimes the bug only occurs under certain environmentally conditions that can not be adequately replicated in-house. With that in mind, it is important to build some sort of diagnostic framework into your product. What types of built-in diagnostic tools have you used or seen used? Logging seems to be the predominate method, which makes sense. We have a fairly sophisticated logging frame work in place with different levels of verbosity and the ability to filter on specific modules (actually we can filter down to the granularity of a single file). Error logs are placed strategically to manufacture a pretty good representation of a stack trace when an error occurs. We don't have the luxury of 10 million terabytes of disk space since I work on embedded platforms, so we have two ways of getting them off the system: a serial port and a syslog server. However, an issue we run into sometimes is actually getting the user to turn the logs on. Our current framework often requires some user interaction.
