Please help! I am pretty "newb" to linux and have no idea what to do. I got the message "your system must reboot to complete updates" (or similar). After rebooting I am greeted with a giant login screen and my 2nd monitor isn't showing anymore.
After logging in, I can only see a part of my desktop -- one giant folder icon. I can right click on the desktop but gives me no option to change resolution or anything.
Any help would be wonderful.
PS: I am able to get a terminal window open. Luckily that ONE folder had a terminal shortcut I had put there. So if this can help troubleshoot, please advise.
EDIT 2: This got me back to Unity working and a nice resolution and both monitors:
apt-get purge nvidia-current rm /etc/X11/xorg.conf reboot now
Unfortunately, now I guess I don't have any HW accel for my graphics card? :(
