Have lost suspend-to-ram functionality on the laptop
Last update on .
Today was the first time I connected a projector to the new laptop. Good news: worked reasonably well, though we couldn't find the option to tell the laptop to display different values on the projector and the screen.
Bad news: something has changed in the settings such that the laptop can no longer recover from a suspend-to-ram. It comes back on and displays a bit of red "corruption" on the screen but is completely frozen (I haven't been able to determine if the keyboard is also non-functional, it seems to be, as e.g. ctrl-alt-f1/ctrl-alt-backspace doesn't refresh the screen).
I use suspend-to-ram every time I use the machine, while I use a projector *maybe* once a month, so it's a bit of a bum deal.

Try to delete your xorg.conf? It worked for me when plugging in an external monitor messed up my usual settings (haven't had problems with suspend, though).
The latest versions of Xorg should run without an xorg.conf file.

No joy there. Loads perfectly fine without the xorg.conf, but doesn't come back from the suspend.
My guess is that using the ATI Catalyst Control Center has set some value that makes the ATI kernel module no longer play nicely with suspend/resume.

Ouch, and now I seem to have lost all OpenGL support (not even software rendering).
