I have an Ubuntu laptop that stops responding when booting up. It will change between consoles with ctrl-alt-FN but pressing enter in the console would not even enter a blank line. The last printed line when booting up in recovery mode was "Skipping EDID probe due to cached edid". Any ideas what might be wrong?

Pressing ctrl-alt-del successfully rebooted it when in that mode. Another symptom is that GRUB stopped booting automatically, not sure if related (I doubt it).

Can you select rescue mode in GRUB's boot menu? It has some options for trying to fix your X config. –  Marius Gedminas Dec 23 '10 at 14:42
    
Can you tell us what kind of graphics hardware you have -- Intel, ATI, NVidia, something else? –  Marius Gedminas Dec 23 '10 at 14:43

Same problem with ubuntu 10.10. Partial solution might be pressing Ctrl + Alt + F1 when Bootsplash appears and then pressing enter. Works for me..

It turned out to be an upgrade that wasn't finished. I started in rescue mode and run the command to finish the upgrade. Then it worked.

Sometimes the problem might be with the window manager. Try getting into the shell without the GUI.

Can you explain, for the OP, how to do so? –  hexafraction Aug 16 '12 at 23:01
