I just installed the latest Ubuntu and then enabled the restricted drivers for NVIDIA
Once I rebooted, the system starts but then enters some kind of graphical test pattern loop
(Blue, Black, White, Grey, and finally all colours in horizontal bars)

At this point the system does not respond to any key combinations or mouse input. Rebooting the system multiple times does not help either.


Just found this post: Ubuntu 13.04 - installation Nvidia driver

The difference being that I cannot even get into a terminal with CTRL+ALT+F1

Update 2:

By booting in recovery mode in a root shell I was able to remove the driver and then follow the instructions from the other post. Same coloured screens as a result.

  • Try CTRL+ALT+T – SimplySimon May 21 '13 at 7:42
  • What about recovery mode? – grimpitch May 21 '13 at 7:46
  • Tried that, will update the question – TimothyP May 21 '13 at 7:47

I seems to me that the display driver has been set (probably by its self!) to the wrong resolution.

On your next reboot, at the Start up options, enter image description here move the mouse cursor down to the Ubuntu Advanced options section of the menu. Click on the second At the Next Screen, choose the following option: enter image description here And finally on the third screen click on the following option: enter image description here This should allow you to boot up and adjust your screen resolution.

Hope this helps

  • let me give that a try – TimothyP May 21 '13 at 7:49
  • Actually.. what menu? All I get is grub – TimothyP May 21 '13 at 7:50
  • Also... I can't see any of the images you posted – TimothyP May 21 '13 at 18:23
  • Ok, using a VPN I was able to view the images, not it makes sense. – TimothyP May 22 '13 at 1:37

    Sorry for the delay in replying, Just had to reinstall everything as I was fiddling with the network and killed it. I am quite new to Ubuntu, and I can not think of anything else at present, but will keep looking. – SimplySimon May 22 '13 at 7:22
