Disable Compiz (change Appearance > Effects to none): No change - C+A+F1 then C+A+F7 to recover. Disable all power management (how? What do you mean by this?) Log out of X, and log into the console, and try suspend/resume (or hibernate, or whatever) from there Again, I don't know the command to suspend from the commandline, but I am fairly confident that it is X because I can C+A+F-key and fix it. Switch virtual consoles and back (alt-ctrl-f1, alt-ctrl-f7 or f8 or f9) As above, this fixes the issue.
