Bug Description
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://
The fix was to run :
$ sudo update-alternatives --config x86_64-
$ 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://
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://
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.
