The machine started normally and I was presented with the login window. But when I entered my password, the screen went black for a few moments and then the login screen came back. + +Since I'm using an [NVIDIA GeForce GTX 750](http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-750), which Ubuntu's Nouveau drivers don't support, I previously needed to install the NVIDIA graphics drivers. + +By entering Ctrl + Alt + F3, I was able to drop to a shell. When I checked `/var/log/Xorg.0.log`, I found a message stating that the NVIDIA driver had failed to load the GLX module, despite earlier messages that it had been loaded. The message also recommended reinstalling the NVIDIA driver. + +In the same shell, I ran: + +``` +$ wget http://us.download.nvidia.com/XFree86/\ + Linux-x86_64/349.16/NVIDIA-Linux-x86_64-349.16.run +$ chmod u+x NVIDIA-Linux-x86_64-349.16.run +$ sudo service lightdm stop +$ sudo ./NVIDIA-Linux-x86_64-349.16.run +``` + +After that, restarting my computer cleared up the issue. -- cgit v1.2.3
