Public bug reported: I'm not sure if this is in the correct package but when I upgraded to Mythbuntu 12.04 from 11.10 I lost OpenGL support for my onboard intel graphics (z68) with a sandybridge processors.
This is not limited to Mythbuntu as I found the fix here http://ubuntuforums.org/showpost.php?p=11600468&postcount=2 The fix was to run : $ sudo update-alternatives --config x86_64-linux-gnu_gl_conf $ sudo ldconfig and select the appropriate glx library because the fglrx library was selected the restart lightdm I've never had nvidia/ati cards installed or have tried to install such so I don't know why flgrx or nvidia-common was installed on my system. I posted more information while trying to trace the problem here http://ubuntuforums.org/showthread.php?t=2004577 Background: On a new system I had installed Mythbuntu 11.10 I performed daily updates through apt-get When MythTV 0.25 was released I upgraded to it. After upgrading MythTV I built the intel drivers and libva from freedesktop.org per instructions on http://www.mythtv.org/wiki/VAAPI At this point everything was working fine. When Mythbuntu 12.04 was released I did a apt-get dist-upgrade to upgrade to the new release. Right after the upgrade I no longer had OpenGL working. I had tried numerous things to get it to work including resintalling x, opengl, mesa, mythtv and more. None of those steps resulted in the linker pointing to the correct library. I don't know if it's a problem with xorg, glx, or something else in the upgrade path so please move this to the appropriate package if necessary. Prior to the upgrade everything was working fine. ** Affects: glx-alternatives (Ubuntu) Importance: Undecided Status: New ** Tags: 12.04 glx glxinfo intel mythbuntu opengl sandybridge ubuntu upgrade vaapi -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1016609 Title: upgrade to 12.04 from 11.10 caused link to fglrx instead of glx on sandybridge system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glx-alternatives/+bug/1016609/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
