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 Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
