Soooo about an hour ago Ubuntu started bothering me about 17 or so updates and, realizing that I wasn't really doing anything important anyways, I decided to simply install them. The install went fine, rebooted aaaaaand...
Suddenly my 1920x1080 display was using a laptop's display size. No warning, no idea what happened.
So first I began by uninstalling Nvidia, figuring that maybe the software update had a conflict with it (I did so by using sudo apt-get remove --purge nvidia -* and, with a few other lines of code, reinstated the nouveau drivers as the primary).
This did a jolly boatload of nothing, so I turned to Google and found the xrandr command.
However, whenever I'd try and re-set the resolution to 1920x1080 (although I also tired 800x600 just to try and fix it) I'd get a message of 'Can't open display'.
So then I stumbled on this thread http://ubuntuforums.org/archive/index.php/t-867506.html
Using a command listed there (sudo DISPLAY=:0.0 xrandr --screen 0 -s 800x600) I got it to stop shouting that it couldn't open the display and got it to start shoutng about how the resolution I chose was not in available modes.
I was able, after a bit of hair-ripping, to coax Ubuntu into opening the display settings (which I could barely use since 50% of the window was taking up 90% of the screen) and found that apparently it's decided my monitor is a laptop, and as such only has one laptop resolution (640x480) available.
So...any suggestions?
