  - by jwdinkc

  After last weeks flash update Hulu desktop no longer works on my Dell laptop though it still works on my HP Desktop. Here's what CLI tells me on the Dell: Inspiron-1564:~$ huludesktop Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory I tried: sudo apt-get install libvdpau_nvidia.so but got E: Unable to locate package libvdpau_nvidia.so and E: Couldn't find any package by regex 'libvdpau_nvidia.so' Hulu does work through the browser and through XBMC. XBMC just doesn't seem to match the video quality of the Hulu Desktop. I don't really know why a nvidia.so is needed for my Intel graphics that comes on Dell Insiron 1564's. anyway. So, do you guys have a solution?

• Unity Launcher missing and Terminal shortcut stopped working

  - by Diana

  When I restarted my Ubuntu after it being updated, I found the Unity launch bar was gone. I tried looking up several solutions online, blindly typing in the commands that others suggested, and I found after the umpteenth time rebooting after typing in another foreign command, I found I couldn't even open up the terminal with the Ctrl+Alt+t shortcut either and I have no idea how to fix this. This was the last set of instructions I remember following before terminal stopped opening. Install CCSM sudo apt-get install compizconfig-settings-manager And then run it in terminal (Ctrl+Alt+t) ccsm Then search for "Ubuntu Unity Plugin". If it's not checked, check it. If it is checked you may have another issue. Try restarting compiz: kill -9pidof compiz` This will kill it, it should start up again, if it doesn't, CTRL+ALT+F2 and then type: sudo service lightdm restart to restart the window manager. Go back to the terminal and run: unity --reset

• How to create and maintain patch on Debian package?

  - by ???

  I want to patch on Trac package. I know how to patch and rebuild the package, but there are some things I don't understand very well. My patch is something dangerous and not likely to commit back to the community. So, let me just say, it's a very private patch. But, I want my patch keep working when the Ubuntu packages upgrade. (Should I apt-get source trac and move my patch to the new version of source directory each time the Trac upgrades?) I see there is a patch/ directory (many using quilt I guess) in debian/, but I don't know how to use it? Will debuild automatic apply all patches in the patch/ directory? And what about dpkg-buildpackage? Is there some environ variables to control the selection of patches to apply?

• HD 6770M low graphics mode after update (AGAIN)

  - by Pihkal

  I have Ubuntu 12.04 LTS (re)installed on this laptop: I've also installed the fglrx-drivers for my ATI card (using apt-get),it appeared to work fine,that is until i updated my distro. Once again i got the "low graphics mode" error when i booted into the new kernel,booting in the old kernel works fine however. When i look into the logs i see "no screen found". This is the second time i install Ubuntu and the second time i run into problems with my graphics. Reinstalling isn't a solution since the problem keeps comming back. My question now is: does anyone know a REAL solution for this issue ar at least knows what's causing it? Any help would be greatly appreciated.

Like it was installed via apt-get?

• cryptsetup partitions not detected at boot

  - by Luis

  I installed a fresh 12.04 and tried to mimic what I had for 10.04. swap should be encrypted with a urandom key and there's another partition that will contain home and other directories. # cat /etc/crypttab | grep -v '^#' | grep -v '^$' cryptswap /dev/sda5 /dev/urandom swap encriptado /dev/sda6 # grep -e 'cryptswap' -e 'encriptado' /etc/fstab /dev/mapper/cryptswap swap swap defaults 0 0 /dev/mapper/encriptado /encriptado ext4 defaults 0 0 I also apt-get install cryptsetup When I boot, the system says (try to translate) that either the partition is not found or is not ready. I should wait, press M for manual or S to jump over. What am I missing here?

• Installing ImageMagick for C(++) on Ubuntu 12.10

  - by user167747

  I'm having a hard time installing the ImageMagick software for Ubuntu 12.10. So, I want the C and C++ API, not much more. Now when I go to imagemagick.org, they have a binary package for unix, namely an rpm. When I download and launch it, RPM complains that firstly I should be using alien, and secondly there are like 10000 missing dependencies. If I use alien to create a deb file, and the install it via the software center, the package does indeed install, but only the command line interface - no includes, anything. Same with apt-get imagemagick. (BTW - wtf, they don't have support for ubuntu?) I tried compiling from source (which I shoudn't be doing anyway - I'm not expecting much customization am I?), and then the includes are present, but the programs won't compile complaining about "undefined reference" and then a list of everything that isn't pure C (and I'm using the command imagemagick.org told me to use, namely cc -o wand pkg-config --cflags --libs MagickWand wand.c) so clearly I'm doing something wrong. Any help would be much appreciated.

• Connect to a VPN from a Virtual Machine

  - by kaharas

  I am running an Ubuntu ditro inside a VMWare virtual machine with a bridged connection on a windows 7 host. What I am trying to do is to have the virtual machine connect to a VPN, but I'm not having much success. At first, the system was using wicd, but I replaced it with network-manager who's supposed to have OpenVPN support. The problem is, even tho i've purged the wicd installation, there're connections shown in the network manager, and still, I'm able to access the net. I've also added the openvpn data in the network manager tab, but it's shown as never used. PS: when I try to stop and start the NetworkManager service, an error message pops up telling me that there's not such a service, but apt-get tells me i've already installed it...

• Steam not opening or responding at all

  - by user109409

  The steam client won't open nor does it display any error message. I have tried right click > Games. I ran steam steam://open/games command, but the client just does not respond. Removing it with apt-get remove steam, deleting the Steam directory & the .deb file and reinstalling it, did not work either. This problem only occurred after I used killall steam.sh to force quit it, it was working fine before. I'm running 12.10 on a 64bit laptop with no additional drivers installed. Anyone else have this problem and a possible workaround? Thank you

• Is there a ppa or repository where we can update LibreOffice to version 3.6?

  - by josircg

  On http://www.libreoffice.org/download/ there is only RPM version - when great majority of Desktop Linux users are using systems based on APT... ppa:libreoffice/ppa seems to be very outdated with version 3.5 It's frustating to see several fixes on Windows version and Ubuntu versions so outdated... People generally reply as: we don't update due to security/stability reasons, etc example 1 example 2 why don't you compile yourself ? For those easy answers, I generally reply: let me decide which version to use at my own risk. I just want to try a newer version and I trust on LibreOffice devs. I understand that update a core lib is very dangerous but Libreoffice is an user application and it don't just break the whole system. Why don't I compile ? Because I am a regular user and don't have time to learn it. I would love to have this time but unfortunately, I don't have. Red Hat/Fedora guys have the same concerns but they update their LibreOffices...

• Ubuntu Server 11.10 AMD64: Installation of graphical desktop changes kernel!?

  - by MindGap

  I've a Ubuntu Server 11.10 amd64 installation that needed a graphical desktop to execute some visual apps. While searching for the correct way to achive this, I noticed that there was a lot of people saying that invoquing the gnome desktop installation (apt-get install ubuntu-desktop) would switch from server to desktop kernel. Is this true!? I've checked and the kernel seems to remain unchanged after the install. I need to be sure of this because the desktop flavoured kernel doesn't seem to support the ServeRaid 8K controller sitting on my IBM server and I have no ideia on how to enable support for it. (I'll be grateful if someone could point me a good guide on how to install ubuntu when the storage controller is not detected) Any comment on this matter will be greatly appreciated! Good linuxing!

• Ubuntu 11.10 Gnome 3 shell doesn't have the Activities menu or launcher

  - by Kelly

  I installed it from apt-get and it only has Applications and Places instead of the Activities menu, it also doesn't have the dock or launcher. Using the super key does nothing, as neither does mousing to the upper left corner. I have also installed the tweak tool, but it looks like all the settings are not being applied to the UI. Am I missing something. I have never used Gnome 3 before as I recently upgraded from Ubuntu 10.4, which I believe was Gnome 2 for the shell. I have been reading the documentation on the Gnome site and it says there should be an Activity menu and other items that aren't there. Thanks

• Software Center won't take into account my changed OpenID name: any idea?

  - by Pascal Av

  Failing to install IntelliJ from the Software Center, I realized my login is wrong in the /etc/apt/auth.conf entry that the install process generates. In this file, I see my original OpenID, that's the one which got automatically generated when signing up on Launchpad. It contains my last name so I changed it. I purged conf and binaries for Ubuntu One, reinstalled, deleted all listed "Devices" from app, all "Applications" from Launchpad. Deleted ~/.cache/software-center/, reboot, but still: When installing IntelliJ, the auth.conf file receives my original OpenID, not the modified one Problem is that the commercial subscription, for IntelliJ private PPA, uses my modified OpenID, so authentication attempt fails. I can't remove nor modify this subscription, even by changing back my OpenID into Launchpad. Any idea to solve this?

  When I try to install a software using Ubuntu Software center I get: Failed to download repository information Check Your Internet connection When I try to do a apt get-install something, I get: 407 Proxy Authentication Required I use a proxy server that requires a user-name and a password. I have set my systems proxy manually, by plugging in the required numbers in the Networks proxy and applied it system wide. I guess the problem now is plugging in my user-name and password.
