Ubuntu 8.10
Dell 24
GeForce 8600 GT
DVI KVM switch
Two days ago, the screen froze. I could log in remotely and run anything from
command line except I could not shutdown and eventually had to do a hard reset.
Today the same thing happened, except this time there was a message on the
(blank) screen:
out of range signal - cannot display this video mode
change computer display input to 1920x1...@60hz.
I switched to the other computer on the KVM, logged in remotely, everything
working fine in shell. I switched back, and suddenly I have Gnome back again.
Hardware problem?
The only resolution available (System -> Preferences -> Screen) is
1920x1200x50hz
Perhaps the incorrect refresh is the problem? Perhaps the KVM is getting in the
way (installed 2 weeks ago).
I've checked xorg.conf but it is entirely generic about monitor settings. Are
they stored elsewhere now?
Suggestions appreciated.
David.
