[ubuntu-uk] Notebook Problems

[Matthew Wild]

Hi,

If it is not a power saving problem, it sounds like X (the graphical
display manager) is crashing.

Do you use desktop effects/compiz, or similar? They are enabled by
default in Gutsy, it could be worth disabling them just to test.
You'll find the options under System->Preferences->Appearance.

Do you have a screensaver enabled? Set it to blank for testing purposes, if so.

When in this state, does Ctrl+Alt+F1 do anything? Ctrl+Alt+F7?
Ctrl+Alt+Backspace?

When rebooting from this state, you may be doing this with a hardware
reset button or similar. See if the laptop responds to the key
sequence in section 4 of this post:

Hope this helps, if not fix, then diagnose the problem :)
