• Supertuxkart not able to start

  - by subeh.sharma

  Was working fine before i played around with NVIDIA drivers and ended up with this problem. I tried running it through the terminal and i see these messages: subsharm@subsharm-ThinkPad-T61:~$ supertuxkart Irrlicht Engine version 1.7.2 Linux 3.0.0-15-generic #25-Ubuntu SMP Mon Jan 2 17:44:42 UTC 2012 x86_64 [FileManager] Data files will be fetched from: '/usr/share/games/supertuxkart/' [IrrDriver] Creating NULL device Irrlicht Engine version 1.7.2 Linux 3.0.0-15-generic #25-Ubuntu SMP Mon Jan 2 17:44:42 UTC 2012 x86_64 [IrrDriver] Trying OpenGL rendering.

• `power/persist` file not found in USB device sysfs directory

  - by intuited

  The file /usr/share/doc/linux-doc/usb/persist.txt.gz mentions that the USB-persist capability can be enabled for a given USB device by writing 1 to the file persist in that device's directory in /sys/bus/usb/devices/$device/power. This is said — if I understood correctly — to allow mountings of volumes on the drive to persist across power loss during suspend. However, I've discovered that the device I'd like to enable this facility for — a USB hard drive — does not have such a file in its corresponding directory, and that attempts to create it are rebuffed. Is there perhaps a kernel module that needs to be loaded for this to work? Do I need to build a custom kernel? I'm running ubuntu 10.10.

• How to stop fan running always on Asus P8P76LE motherboard with ATI Radeon HD6900

  - by Chris Good

  I'm using Ubuntu 12.04 LTS. I'm not sure if it is the CPU (i7) fan or the video card fan. I've tried using lm-sensors & fancontrol sudo sensors-detect Now follows a summary of the probes I have just done. Just press ENTER to continue: Driver `w83627ehf': * ISA bus, address 0x290 Chip `Nuvoton NCT6776F Super IO Sensors' (confidence: 9) Driver `coretemp': * Chip `Intel digital thermal sensor' (confidence: 9) To load everything that is needed, add this to /etc/modules: # Chip drivers coretemp w83627ehf Like many people, I'm also getting error: /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed Here is the output of sensors: # sensors radeon-pci-0100 Adapter: PCI adapter temp1: +71.0°C coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +44.0°C (high = +80.0°C, crit = +98.0°C) Core 0: +44.0°C (high = +80.0°C, crit = +98.0°C) Core 1: +40.0°C (high = +80.0°C, crit = +98.0°C) Core 2: +43.0°C (high = +80.0°C, crit = +98.0°C) Core 3: +42.0°C (high = +80.0°C, crit = +98.0°C) I'm hoping some-one has already solved this for my configuration because this seems to be a problem for many people and there are many different suggestions.

• Add Custom Launcher in 11.10

  - by sayth

  I started by searching guides. I found this guide but neither of the main methods works anymore in 11.10. The first solution, I have created the desktop file, however the file location given as .gconf-> desktop-> unity-> launcher -> favourites no longer exists. I can get to /home/sayth/.gconf/desktop but there is no longer a unity folder. The second solution described right-clicking the desktop and creating a launcher. Right-clicking the desktop no longer produces a "create a launcher" option. I manually installed geany 0.21 as the one in the repo's is outdated. It's installed and working correctly, and is executing from /usr/local/bin/geany. How can I add it to the launcher?

• Jupiter seems to break multimonitor setup

  - by Philippe

  If Jupiter is in the startup my multimonitor setup will fail. Instead of two separate desktops the monitors will be mirrored, one over the other with the smaller notebook-desktop in the larger screen: After each new log-in I have to reset the Display settings in the "System Settings..." dialogue to two not mirrored screens, the changes don't seem to be saved. Given the the entry from xsession-errors /usr/lib/jupiter/scripts/resolutions: line 42: /var/jupiter/available_resolutions_LVDS: Permission denied I assumed that it's coming from Jupiter. Infact, if Jupiter is removed as startup application the desktop settings are fine. Any idea how to solve that issue?

• How to configure permanent autologin?

  - by DanielGibbs

  I'm trying to set up an Ubuntu 12.04 machine as a kiosk and I would like it, on boot, to automatically log in as my kiosk user "kiosk", and start the appropriate display manager, in this case blackbox. I have configured /etc/lightdm/lightdm.conf as in this question and have an appropriate /usr/share/xsessions/blackbox.desktop to launch blackbox. I managed to get initial autologin by using the dbus-send method in this question, however if I right-click and select "Exit" from blackbox, then I am taken back to the login screen. How can I configure lightdm/ubuntu to always autologin as "kiosk" instead of displaying the login screen? Or, failing that, how can I configure blackbox to not display a menu when I right-click?

  Running Precise. I am tweaking the ambiance theme to my taste.

• Do Not Uninstall Flag on Apt?

  - by Daniel C. Sobral

  Does the Debian/Ubuntu package infrastructure has some way of marking packages so that they never get uninstalled, no matter the pinning of other packages? My problem is that, sometimes, packages installed by Puppet (coming from non-standard repositories, of course) cause other packages to get uninstalled -- in particular, openssh-{server,client}. The way this happens is that package A and B depend on different versions of package C. If A is installed and one asks to install B, then the version of C changes. The new version of C is incompatible with A, so A gets uninstalled. The funny thing is that the process is then reversed, as, on the next run, Puppet notices that A is not installed and tries to install it. So, basically, I want to make sure A never gets uninstalled, which would prevent B from getting installed. That would be reported as an error, making me aware of the issue. If anyone cares, Puppet uses the following command to install packages: /usr/bin/apt-get -q -y -o DPkg::Options::=--force-confold install <package>

• Why can't I use Unity 3D on a ATI Mobility Radeon HD 4200 Series with FGLRX drivers?

  - by user88257

  With a brand new install of 12.04 on my Dell Inspiron M5030, Unity 3D appears to load everything but the icons in the top left, and I am unable to click on anything. Unity 2D seems to works fine however. I have done nothing except install Synaptic Package manager and follow this guide to install FGLRX Drivers under Settings ? Additional Drivers, the driver shows as installed and functioning. Also after running: /usr/lib/nux/unity_support_test -p, I get this: OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: ATI Mobility Radeon HD 4200 Series OpenGL version string: 3.3.11653 Compatibility Profile Context 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 am unsure as to what the problem is. I have tried the non-proprietary drivers, I could not get them to work either, but I would be willing to try again.

• Allow sudo on specific file from active directory group

  - by tubaguy50035

  I have an Ubuntu Server 12.04 box that has active directory integration running on it. I want to allow a certain active directory group access to execute a script as sudo. I want to do something like this: %programmers ALL=NOPASSWD: /usr/local/bin/createSambaShare.php When I log in with my active directory user and issue groups I do not see the group programmers, but I am a part of the programmers group within active directory. I've set up the group under the Unix attributes tab and given it an id of 1000 and added my user to it. My first thought was that I needed to add the group to the Ubuntu box. When I tried to do that, it told me that the programmers group already existed. What am I missing here?

• Add autorandr before kdm starts

  - by Serge Tarkovski

  I want to add autorandr before kdm starts. Autorandr works well within KDE, however, in kdm I still have ugly 1024x768 resolution when my external monitor is connected. I tried adding autorandr --change to /etc/kde4/kdm/Xsetup: #! /bin/sh # Xsetup - run as root before the login dialog appears #xconsole -geometry 480x130-0-0 -notify -verbose -fn fixed -exitOnFail -file /dev/xconsole & /sbin/initctl -q emit login-session-start DISPLAY_MANAGER=kdm /usr/local/bin/autorandr --change >> /tmp/autorandr echo "Xsetup finished" >> /tmp/xsetup-finished A debug message in /tmp/xsetup-finished appears correctly. /tmp/autorandr is empty (so it seems autorandr runs without errors). I also tried to move autorandr --change line before /sbin/initctl -q emit login-session-start DISPLAY_MANAGER=kdm with no effect. P.S. Of course, autorandr profiles I created under KDE session, are in my home folder, but Xsetup script runs under root, so I created a symlink from my ~/.autorandr to /root/.autorandr.

• Unable to change the launcher icon size

  - by takeshin

  After upgrading to 11.10 I can't change the launcher icon size to smaller. I've tried to change it using ccsm, like described in How can I configure Unity, but the changes take no effects (restarted, tried sudo - still big icons). In the previous version of Ubuntu this solution worked. How can I change the icon size? (BTW, how can I know which Unity (2D vd 3D) I'm running and switch between?). Edit: Looks like I'm using Unity 2D and have some problems with graphics: me@my-laptop ~ $ /usr/lib/nux/unity_support_test -p Xlib: extension "GLX" missing on display ":0.0".

• Is LightDM is broken? Autologin works

  - by Ben

  I recently upgraded my Mythbuntu box to 11.10. LightDM worked for a while and then I configured autologin on my user account. After some time, I've removed some packages to lean down the system. Now when I log out (from either Unity or Gnome Shell) I lose the X session, LightDM doesn't start back up. If I disable autologin through /etc/lightdm/lightdm.conf I get no login screen & no X. As I said, autologin works and gives me a Ubuntu Classic desktop. This is the only reference in dmesg to lightdm; [ 17.351023] type=1400 audit(1329530135.420:19): apparmor="STATUS" operation="profile_load" name="/usr/lib/lightdm/lightdm-guest-session-wrapper" pid=1097 comm="apparmor_parser" Can anyone help?

• AWStats: cannot access /var/log/apache2/access.log

  - by Joril

  I installed awstats on my new Ubuntu Lucid server, but when cron tries to run it as user www-data, it complains that cannot access /var/log/apache2/access.log: Permission denied. In /usr/share/doc/awstats/README.Debian there's this paragraph: By default Apache stores (since version 1.3.22-1) logfiles with uid=root and gid=adm, so you need to either... 1) Change the rights of the logfiles in /etc/logrotate.d/apache so that www-data has at least read access. 2) As 1) but change to a specific user, and use the suEXEC feature of Apache to run as same user (and either change the right of /var/lib/awstats as well or use another directory). This is more complicated, but then the logs are not generally accessible to the server (which was probably the point of the Apache default). 3) Change awstats.pl to group adm (but beware that you are then taking the risk of allowing a CGI-script access to admin stuff on the machine!). I'd go with 1, but what are the recommended permissions to grant?

• OpenOffice doesn't work

  - by dn.usenet

  I installed OpenOffice on 12.04, and set it as the default utility for spreadsheets, but it doesn't run at all. While trying to troubleshoot, I read that it is not recommended to install it alongside LibreOffice. I am about to uninstall OpenOffice because I don't know how to get it working, and LibreOffice is opening my spreadsheet just fine. But just out of curiosity, I also read that I should try deleting .openoffice.org folder; but from where? I don't see it under /usr/lib, nor under my /home.

• Creating symlink for Postgres

  - by Edwin

  As a developer, I often ssh right into my local database, just to test my application before pushing my code. However, I find that every time I want to access Postgres, I have to type in postgres@ubuntu:~$ /usr/local/pgsql/bin/psql test whereas on my work machine, all I have to do is type postgres@ubuntu:~$ psql --dbname=test --username=user I tried creating a symlink, which was successful, but whenever I try connecting to it through this shortcut, I get the following error message: psql: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"? How do I get this to work? In case it makes any difference, I'm using a self-compiled version of the 9.1.x series.
