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?

to solve the first problem you just need to delete the xorg.conf file easily this way (as root):

sudo rm /etc/X11/xorg.conf

the system should generate a new one automatically if not used the default one and you probably should install your nvidia card's driver.

*always make a backup of a file before deleting it (copy contents and save with different name or tag like xorg.conf.backup .e.g) *

for the second problem, it happens with nvidia usually if you didn't install the driver or you are using too much desktop effects while you have nvidia card

currently i believe ubuntu 11.x is unstable with nvidia cards so don't pressure it with lots of graphics , 10.X was more stable unfortunately i think i'm gonna switch back to 10

  • if you need me to explain the steps of installing nvidia driver i'll be glad to help good luck

Ubuntu 11.10 doesn't boot sometimes correctly, showing the user a black screen. I don't know how to prevent this, but I know how to get the graphical shell back when it happens.

CTRL+ALT+F1 then:

  1. enter user name
  2. enter password
  3. sudo restart lightdm ; exit
  4. enter password

I know this is a old question, (8+ years) Although; hopefully if someone in the future has the same problem, this may help:

Copy pasted from my own answer:

sudo apt update
sudo apt upgrade
sudo apt autoremove

sudo apt remove ubuntu-desktop
sudo apt autoremove
sudo apt install ubuntu-desktop

or

sudo apt-get install ubuntu-gnome-desktop

Ubuntu boots to black screen with cursor after upgrade (from 18.04 to 20.04)
