--- Comment #9 from Jeff Blake jeffblake0@gmail.com --- Tasev,
If your issue is related to mine then the corresponding debs from the 9.3~git1309201759 Sept 20th release should work :-
https://launchpad.net/~oibaf/+archive/graphics-drivers/+build/5036069 [amd64] https://launchpad.net/~oibaf/+archive/graphics-drivers/+build/5036070 [i386]
...and the debs from Sept 23rd 9.3~git1309231016 should fail :-
https://launchpad.net/~oibaf/+archive/graphics-drivers/+build/5042397 [amd64] https://launchpad.net/~oibaf/+archive/graphics-drivers/+build/5042398 [i386]
To find out which mesa packages you have installed (hopefully nothing else has a matching version string) :-
dpkg -l | grep ".*9.3~git[0-9]*.[0-9a-z]*~gd~.*"
To install the debs download the appropriate packages to /path/to/some/directory and then :-
cd /path/to/some/directory
sudo dpkg -i *.deb
You can usually find the debs from an older mesa version by looking in apt's archives :-
ls -lrt /var/cache/apt/archives/*_9.3~git[0-9]*.[0-9a-z]*~gd~*
And copy them somewhere for easy installation :-
cp /var/cache/apt/archives/*_9.3~git1309040912.644fbb~gd~* /path/to/some/directory
Hopefully you can find out which version breaks your install or at least get things working again.
