Bug #271
Error After Upgrading NVIDIA Drivers Causing Window Manager to Crash
Description
After installing Steam on one of my Linux boxes, I decided to try out a one of the flagship games for Linux on Steam. When I launched Steam I got a message saying that it is recommended to use the nvidia-304-updates driver. I ran jockey-gtk and chose to install the nvidia-304-updates and then rebooted the system. After the reboot the normal login screen did not show up and instead an error showed up:
NVIDIA: API Mismatch: The number of created screens does not match the number of detected devices
The problem was with conflicting drivers being installed, I checked this by running:
sudo dpkg -la | grep nvidia
nvidia-304 nvidia-304-updates
In order to fix this problem, I ran:
apt-get remove --purge nvidia-304 apt-get autoremove apt-get clean reboot
