LinuxQuestions.org - [SOLVED] Debian Wheezy: OpenGl suddenly stopped working

- Debian (https://www.linuxquestions.org/questions/debian-26/)

- - Debian Wheezy: OpenGl suddenly stopped working (https://www.linuxquestions.org/questions/debian-26/debian-wheezy-opengl-suddenly-stopped-working-908428/)

Code:

cd /etc/X11

mv xorg.conf xorg.old

Reboot, test for the problem.

Code:

cd /etc/X11

mv xorg.old xorg.conf

Code:

aptitude remove libtxc-dxtn0

Check for the problem (you shouldn't need to reboot or restart x for that one)

Code:

aptitude install libtxc-dxtn0

etc

I honestly don't think it's the absense of libtxc-dxtn0, as that only provides s3tc in an external lib, which opengl does not require. As far as I know none of the programs you listed require it, it's only needed/used by some games.

The DRI permissions problem is the more likely one. I've always set up an xorg.conf with at least those contents, so I can't say if that's always the case when it's missing.

Yes, that was my impression as well. I'll try the experiment of removing xorg.conf when I have a free moment.
