Why is this bug against ubuntu-drivers-common then? Since downgrading it didn't help, and your description mentions installing various updates, the problems could be caused by any of them right?
You can find out what packages was upgraded when by looking in dpkg log files: /var/log/dpkg.log*. Then you could downgrade the packages. If your system then works again, you would then install one upgrade at a time, to find out what package breaks your system again. This might not be the easiest way to troubleshoot your issues, but it is probably what I would do. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ubuntu-drivers-common in Ubuntu. https://bugs.launchpad.net/bugs/1373968 Title: GUI does not work after update Status in “ubuntu-drivers-common” package in Ubuntu: Confirmed Bug description: After logging into PC today and running the software updater, various system updates were downloaded. I was promped to restart, which I did. At reboot, the system would get as far as displaying the login screen. After I entered my password, the system appears to hang, with no disk activity. I have a dual monitor system, but only the left monitor is active, in that it displays a purple Ubuntu splash screen, without the login box. I have tried restarting a number of times, but the result is always the same. I can log in by using the advanced options and drop into the root console.
