Yesterday the set of packages below [1] was updated. I shut down, booted this morning and found out that I was not shown the lightdm login screen: I was stuck at the purple screen that precedes it (into which I enter my disk encryption password). Now the funny thing is that I could hear the lightdm startup sound and could actually login by typing my password (disk activity and started processes verify I am actually logged in), but I can't see anything: I'm still stuck at the puple screen. Uninstalling the nvidia drivers solved the problem: I'm typing this in a browser window using the nouveau drivers. I atttempted switching to nvidia-304, but that doesn't work either. Using those drivers I am shown the lightdm login screen, but after logging in I'm stuck with a screen showing only the background image. Nothing else is available, no keyboard or mouse trickery will reveal any menu, dialog or terminal to gain access. Since nouveau doesn't support a multi-monitor setup, it would be great if I someone could tell me how to get the nvidia drivers working again.
