Today I installed the daily updates and then a funny thing happened... I was playing Morrowind on Wine, and in the game I tried to navigate to the video settings menu to adjust the brightness. I had done this before many times with no problem. As soon as I clicked "video", the game silently crashed and returned me to my desktop. The funny part was that my second monitor, which normally remains "signaled" with a black screen, while playing Morrowind, was now showing signs of "no signal". A quick check in nvidia-settings showed that my second monitor stopped being detected. I thought... ok, no big deal, I'll just restart and everything will be OK... WRONG. Upon restarting, X would not start because the NVidia driver compiled for 3.5.0-18-generic went missing, as in, it was not shown in
lsmod. The monitor that had disappeared also did not come back. So I thought, ok, I must have gotten a new kernel, maybe now I have to reinstall the driver. Sure enough,
uname -r showed
3.5.0-19-generic, one tick newer. So I
sudo apt-get remove --purge nvidia-current-updates and then
sudo apt-get install --reinstall nvidia-current-updates. The files downloaded and the module compiled successfully with no warnings or errors.
At this point, the lightdm login screen works fine across both monitors, but after logging in, I only get my desktop background image. No Unity or desktop icons. The strange thing is, the X log has no errors. After a few restarts, I finally got the second monitor to come back online after physically removing my GPU and putting it back in.
I'm pretty puzzled about this whole thing, whence I ended up here. Any one have any clue what's going on? I just want my desktop back :/
