Unfortunately the recent upgrade to version 1:0.2.91.7 broke X. Starting lightdm would fail, delete my xorg.conf and redirect libgl symlinks to mesa. After some debugging I fond that this was done by gpu-manager, because it incorrectly believes that my nvidia module is blacklisted. gpu- manager.log contained "Is nvidia blacklisted? yes". More debugging determined that this was happening because I have a several years old file named: /etc/modprobe.d/blacklist.dpkg-old which among other things contain the line "blacklist nvidia". However that is _not_ a modprobe config file. modprobe only uses files with a .conf extension. (See the man page modprobe.d(5)). Unfortunately gpu-manager does not have this restriction and looks in all files in /etc/modprobe.d by running: grep -G "blacklist.*nvidia[[:space:]]*$" /etc/modprobe.d/* I could work-around the bug by removing the .dpkg-old file. However this will likely break other machines as well. I found two bugs 1373968 and 1374871 about X not working after installing the latest update. However they does not contain enough information to determine if they are duplicates of this bug or not.
