Booting the system with both displays attached shows only the working monitor in the display settings.
When booting the system with only the non-working monitor attached actually shows the desktop on the non-working display, but in a wrong resolution - and the display settings application does not show any monitor at all (see screenshots). ** Attachment added: "display settings with the broken monitor attached only" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/914437/+attachment/2682246/+files/2012-01-19%20display%20settings%20no%20monitor.png -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/914437 Title: Second display not recognized anymore; "EDID checksum is invalid" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/914437/+subscriptions _______________________________________________ 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
