  - by Jason Fitzpatrick

  We’ve seen desks with LEDs under frosted glass before, but this is the first desk we’ve seen where the LEDs serve as a sophisticated notification system. Check out the video above to see desk, designed by Michael LaGrasta, in action. The secret sauce is an array of LED modules, linked to an Arduino board, which is in turn running a tiny web server.

• Configure Dual Boot, Windows 7 and Ubuntu 12.04 with or without EFI

  - by Keroak

  I have just installed Ubuntu 12.04 on a laptop with Windows 7 but I don't get to boot from Ubuntu. First, during the installation I made these partitions (may be too many): /dev/sda1 FAT32 SYSTEM 200Mb boot (EFI boot, i guess) /dev/sda2 unknown file system 128 Mb msftres (Windows Boot Manager) /dev/sda3 NTFS OS 100 Gb (Windows 7) /dev/sda4 NTFS DATOS 315 Gb (Data partition) /dev/sda5 ext4 28 Gb (/home) /dev/sda8 unknown file system 1 Gb biog_grub (i'm not very sure why i made this one) /dev/sda6 ext4 17 Gb (/ Ubuntu 12.03 installed withou errors aparently) /dev/sda7 linex-swap 2 GB (swap) I can boot from Windows perfectly. Actually I tried to configure Windows Boot Manager with EasyBCD but it doesn't recognize any boot entry. Anyway, I added an Ubuntu Entry and it configured it automatically. Now I have boot entries the Windows 7 one that appear to work and the Ubuntu 12.04 that it prompt a "No application found" message. I re-started from a USB with Ubuntu and tried to fix GRUB from the command-line and with boot-repair. No results. As far as I understand I have to tell the Windows Boot Manager where my Ubuntu boot loader is. So I have two problems: Actually, I don't know where my Ubuntu boot loader, GRUB or GRUB2 or whatever, is. I don't know how to set my Ubuntu entry in Windows Boot Manager. I guess using BCDedit.exe as EasyBCD didn't show me the entries. Anyway, I don't know what parameters to use. I read several articles about it but i didn't find out anything useful.

• Running 12.04 on a Dell Inspiron 1545 having random system lockups

  - by Kris

  I just reinstalled a fresh 12.04 because I couldn't even get booted on my previous installation anymore. I just installed 8GB of ram on this laptop, but the problem happened even before this, and all I have installed in this run on Ubuntu is: ia32libs, Oracle JDK7 and the 32bit JRE junipernc jupiter The laptop has never been used very heavily, so could someone get back to me on this, let me know what further information you need about my machine, or files to upload. Thanks!

• Server auto-installed Decnet during dist-upgrade

  - by nixnotwin

  When I did a dist-upgrade of my ubuntu 10.04 server, it automatically installed Decnet, and it trew up ncurses based configuration wizard. I have never heard of Decnet, but I followed the instructions in the wizard, and accepted for it to be installed, and it lead to the disconnection of 2 of my internet uplinks, and the hosted website stopped responding on WAN side. Then I purged Decnet, and rebooted the server, and everything went normal. So why did my server install Decnet when I did dist-upgrade?

• set default java version

  - by Dónal

  I have been using Java 6 on Ubuntu 11.10, but now I want to update to version 7. I've installed version 7 via PPA as described here. If I run sudo update-alternatives --config java I get the following output: There are 2 choices for the alternative java (providing /usr/bin/java). Selection Path Priority Status ------------------------------------------------------------ 0 /usr/lib/jvm/java-7-oracle/jre/bin/java 64 auto mode 1 /usr/lib/jvm/java-6-sun/jre/bin/java 63 manual mode * 2 /usr/lib/jvm/java-7-oracle/jre/bin/java 64 manual mode Similarly, if I run: sudo update-alternatives --config javac I get the output: Selection Path Priority Status ------------------------------------------------------------ 0 /usr/lib/jvm/java-7-oracle/bin/javac 64 auto mode 1 /usr/lib/jvm/java-6-sun/bin/javac 63 manual mode * 2 /usr/lib/jvm/java-7-oracle/bin/javac 64 manual mode So it looks like version 7 is already the default. But if I run either java -version or javac -version The output indicates that version 6 is still the default. How can I set the default to version 7?

• Remove gradients from elementary theme?

  - by John

  I really don't like the gradients in the elementary theme, and I was wondering if there were a way to remove them, from applications like Nautilus-Elementary, Postler, Dexter, etc. I've tried commenting out the Apps/[Application].rc in /usr/share/themes/elementary/gtk-2.0/gtkrc but it doesn't work, still leaves the gradients in their place. I'm a big fan of the other controls in the theme; the scroll bar, the way it borders gedit and the buttons, and I'd like to keep these features, but I don't like the way it styles its windows. Thanks for any help, as always!

• flash video appears blue ubuntu 12.04

  - by pst007x

  This is a duplicate, however the solution given does not work. After updating to Ubuntu 12.04 from Ubuntu 11.10, all video is now blue, whether playing in a browser or a player. I have tried to uninstall all Flash and re-installed but makes no difference. Does anyone have any ideas? Fix (work around) Issue: All web browsers flash player video is blue Chromium Google Chrome Firefox Both flash plugins causes flash video to appear have a blue overlay, so remove. Adobe - flashplugin Flashplugin - installer Solution (not as functional as adobe flash plug in but it works) Install Lightspark (plus any browser-plugins) or Install Gnash (plus any browser-plugins) FIX (Possible) Removed: Gnash-browser plugins Video Decode and Presentation API for Unix (libraries) libvdpau1 Installed: Adobe-flashplugin Re-started browser, and it worked for me.

• How can I restore a corrupted Shotwell db?

  - by Yann Dìnendal

  While I was importing photos from a SD card in Shotwell, my laptop has crashed (shutdown because of over-heating). Now, I can no longer launch Shotwell: $ shotwell ** ERROR:x86_64-linux-gnu/db/VersionTable.c:104:version_table_construct: assertion failed: (res == SQLITE_OK) If I move the .db file ~/.shotwell/data/photo.db elsewhere so it is no longer present (but backed-up), shotwell will launch, but will rebuild its library, which will be empty. I can re-import the folders shotwell creates, but I lose nearly all meta-data (most importantly the "folders", or events, and their main picture) Is there a way to repair/rebuild/restore photo.db? How can I see what's inside? how bad it's damaged? Or is there another way to get back my events and imports?

• Brand new battery is 100% charged but at 0% capacity

  - by Chris Conway

  I just bought a brand new battery to replace one that had seemingly died. I followed the instructions that came with the battery and charged it overnight, then ran my computer on battery until it was in a critical state and charged it overnight again. Now the battery appears to be 100% charged and at the same time at 0% capacity—when it's plugged in it doesn't charge and when it's unplugged the computer immediately goes into low power mode. I've taken the battery out and checked the contacts. I've rebooted the system with and without the battery. Nothing seems to help. I'm not sure if I should blame the battery, the laptop, the charger, or the power management software for this state of affairs. The obvious answer would be the battery but I bought this battery because another year-old battery exhibited similar behavior—I assumed it was dead and a Dell tech came to the same conclusion. I'm loathe to order another new battery without first exploring other explanations. What can I do to diagnose this problem? Here's the /proc info: $ cat /proc/acpi/battery/BAT0/state present: yes capacity state: critical charging state: charged present rate: 1 mA remaining capacity: 0 mAh present voltage: 9754 mV $ cat /proc/acpi/battery/BAT0/info present: yes design capacity: 6600 mAh last full capacity: 6789 mAh battery technology: rechargeable design voltage: 11100 mV design capacity warning: 660 mAh design capacity low: 200 mAh cycle count: 0 capacity granularity 1: 66 mAh capacity granularity 2: 66 mAh model number: DELL WK serial number: 4043 battery type: LION OEM info: SMP

• Gnome-Screenshot error in Ubuntu GNOME 13.10

  - by Lucas Zanella

  I recently installed Ubuntu GNOME 13.10 (it came with GNOME 3.8, but I replaced by GNOME 3.10) and after a few problems, the only one I couldn't solve was the screenshot problem. When I press the PrtSc key, nothing happens. No sound, no nothing. When I execute it via Terminal by writing "Gnome-Screenshot", it does work and saves in my Pictures folder. I have already tried to re-install the program, but still didn't work. I also tried to create a shortcut with this command line, but still nothing happend. I tried to replace the PrtSc key by another one, just for make sure the problem wasn't in the key, and it still failed. Can anyone help me?

• Should security updates 'always' be installed?

  - by kmansoor

  We are a small shop, no real sysadmin. So developers (Java EE) also try to maintain Ubuntu server 12.0.4. When I login a terminal and I see messages like: 6 packages can be updated. 6 updates are security updates. Should all security updates always be installed? can some be ignored? Should these be acted upon immediately? Or one could wait for 2:00 AM coming Sunday? Is there a way to know a 'critical' update? Is there a good sysadmin for dummies resource I should be reading?

• GNOME lock screen (screensaver) is missing music controls

  - by oleg

  I have a custom Ubuntu 12.10 configuration (started out as a minimal installation of Ubuntu 12.04 with a number of other packages such as Gnome Shell selectively installed via apt-get and then upgraded to 12.10). (Almost) everything works just fine. However, the lock screen (Gnome screensaver) does not expose a UI to control music playback. Whenever I have Rhythmbox running in the background I cannot pause music playback without unlocking the screen. Obviously some package(s) or configuration bits are not present but I am not able to figure out what needs to be added or done in order to enable playback control in the lock screen. Any idea what I might be missing? Ideally I would not like to install Ubuntu desktop only to get music controls in the Gnome lock screen.

• Do we really need a thousand Linux distributions?

  - by nebukadnezzar

  Pointed from an answer to a (possibly related) question, I came across this graphic, and I'm shocked how many linux distributions currently exist. However, it seems that most of these distributions are forks of already popular distributions with minimal changes, usually limited to themes, wallpapers, buttons, the kind of stuff most people probably wouldn't see as a reason to fork a Linux distribution. Of course, someone will always say "Opensource is also about the freedom of choice", and while I wholeheartedly agree, I do not believe that this is a valid reason to fork an already perfectly working Distribution into a new one, which might possibly result in less security/stability due to smaller group of developers. There's another problem: Those, who want to switch to Linux, are confronted with a neverending list of Linux distributions, and wonder rightfully which they're supposed to chose (infact, I was facing that problem before I've discovered Ubuntu). There might be (very few) valid reasons to fork a distribution: Specializing on a particular topic (FOSS Only, work-related topic (i.e., for a Hospital), etc) An exceptional architecture, that requires a special set of software Use of non-FOSS, propietary technology, and such But even with these points in mind, it would still seem easier to create a subdistribution with the required changes, such as XUbuntu with XFCE4, KUbuntu with KDE4, Fluxbuntu with Fluxbox, etc. So, why exactly do we need so many distributions?

• Lubuntu: neither shut-down nor restart works

  - by Rantanplan

  aI have a freshly installed Lubuntu 14.04.1 (installed with forcepae option on a laptop with Pentium M processor). The only problem that I have found so far is that I cannot shut-down or restart the laptop. It always continues showing "Lubuntu" and some dots. Pressing Esc it says wait-for-state stop/waiting * Stopping rsync daemon rsync [OK] * Asking all remaining processes to terminate… [OK] * Killing all remaining processes… [fail] ModemManager [597] : <info> Caught signal, shutting down… ModemManager [597] : <info> ModemManager is shut down nm-dispatcher.action: Could not get the system bus. Make sure the message bus daemon is running! Message: Did not receive a reply. Possible causes: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. * Deactivating swap… [OK] * Will now halt The cursor remains blinking but the only way to switch it off is to hold the power-off key pressed for some seconds. I tried sudo shutdown -h now, sudo halt and sudo poweroff resulting in the same problem. I also tried to add acpi=force in GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" in /etc/default/grub and run sudo update-grub; then, using the taskbar's shot-down button lead to a direct stop of the laptop equal to holding the power-off key pressed for some seconds. Next I followed the answer http://askubuntu.com/a/202481/288322. Now, I directly receive some messages during shut-down starting wait-for-state stop/waiting * Stopping rsync daemon rsync [OK] * Asking all remaining processes to terminate… [OK] [ 240.944277] INFO: task kworker/0:2:24: block for more than 120 seconds.

ModemManager [576] : <info> ModemManager is shut down * Deactivating swap… [OK] * Will now halt [ 600.944276] INFO: task kworker/0:2:24: block for more than 120 seconds.

Then, nothing more was coming during the next 5 minutes. If you know where can I find relevant error information, I will be happy to search for them.

• Problem with webcam after changing camera input to my iPhone's camera [closed]

• How to get the Ubuntu look back after installing lubuntu-desktop

  - by Wauzl

  I have a fresh install of Ubuntu 13.10. I wanted to try out Lubuntu, so I installed the package lubuntu-desktop. Everthing worked fine, I can do Lubuntu sessions now, as well as normal Ubuntu sessions with unity. I realized that I liked unity better. Unfortunately, since I installed lubuntu-desktop my login screen and my notifications look different. How can I revert this and get my old Ubuntu look back? I already removed the package lubuntu-desktop, but it did’t help. Also, when I installed it, it came with a lot of packages that weren’t removed when I removed lubuntu-desktop

• Android device unable to obtain ip address connecting to AP created with Hostapd

  - by user114392

  I have a wired internet connection that works behind an authenticated proxy server. I followed the steps mentioned here and managed to create a hotspot which my google nexus 7 detects. However, it seems stuck at "obtaining an ip address" and is not able to connect to the internet. I initially received the following error message when running the script in the terminal: dnsmasq: failed to create listening socket for 127.0.0.1: Address already in use [fail] I figured it is because of a conflict with the network manager, I commented out the "dns=dnsmasq" line in the nm configuration file. After a network-manager restart, the first error doesn't show up but I get the following: Configuration file: /etc/hostapd.conf Failed to create interface mon.wlan0: -23 (Too many open files in system) Try to remove and re-create mon.wlan0 In both cases, however, the hotspot is created and is detected by my android device. only that it cannot "obtain an ip address" and connect to it. Is it because my eth0 connects via a proxy server? Or could there be something wrong with the dnsmasq config? Any help would be appreciated.

  I want to change the upload_max_filesize = 2M to 50M, then I started edit on php.ini, but when try to save it, it displays error message below Could not create a backup file while saving /etc/php5/apache2/php.ini gedit could not back up the old copy of the file before saving the new one. You can ignore this warning and save the file anyway, but if an error occurs while saving, you could lose the old copy of the file. Save anyway?
