I have just upgraded via the update manager from 11.04 to 11.10 and have a problem in that after rebooting I have no visible screen, just an extremely thin line along the top of my monitor. As I am running on AMD64 with an Nvidia card I tried the solution outlined here as regards renaming my xorg.conf file via a 11.04 live CD, but this has not worked.
According to GRUB my new updated kernel is 3.0.0-11 (Development Branch) and I must say that I was unpleasantly surprised that a distribution upgrade via the update manager on release day would upgrade me to a development release. Can anyone offer any advice as to how I can solve this problem?
EDIT - update on problem
After perusing many forum entries, entry #27 for 64-bit here actually worked. After "sudo reboot now" I got into the GUI and everything seemed OK. Then went to update manager and found I had 700MB plus of updates to still install. Started installing them, and while update manager was running in the background I attempted to open Firefox. The screen immediately went to a multi-coloured "sandstorm" and everything froze - neither the mouse or keyboard had any effect. All I could do was reboot by pressing the reset button, and since that the system only boots into tty1. What now?
