I'm commenting to explain my solution for the posteriority: - It seems that watching a video from tv-out in Windows (dual boot) screwed up my monitor ( acer al2216w ). I started getting the "bad edid checksum" errors from X.
- The problem appeared simultaneously on Ubuntu 9.04 and Debian "Lenny" (yes, I have 3 operating systems on my hard drive). - I solved it by "rebooting" my monitor - that is I unplugged it for a while, and reconnected it. This should definitely be tried before any other tweaks. - Even without monitor reboot, the windows drivers worked fine; it was the Ubuntu drivers that required it. -- [hardy] NVIDIA driver doesn't work after upgrade from 7.10: invalid EDID checksum https://bugs.launchpad.net/bugs/221808 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg 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
