I have the same problem, but I think I think the real problem here is not suspend/resume but VT handling. using the suggestion to remove "add_parameters --quirk-no-chvt" works for me -- but only I have have only one user logged in.
If I have more than one user logged in (= more than one X server running), than one of the Xorg processes hangs and uses 100% of one CPU core. Swiching to that user's Xserver/VT (via alt+ctrl+fX or using the graphical session switcher) hangs the system. If that happens, I have to ssh into that machine and kill -9 the Xorg process - than at least the other users session can live on. If I add "add_parameters --quirk-no-chvt" again and resume from sleep with two users logged in than I have to press alt+ctrl+f1, alt+ctrl+fX and have a 50% chance of going to the "good" Xorg that is not hanging. If I hit the "bad" Xorg that hangs at 100% cpu, I have to ssh and kill -9 the Xorg process to make the system usable again.... -- [lucid regression] random graphics effects after resume from suspend to RAM https://bugs.launchpad.net/bugs/510004 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
