My dual monitor setup has been broken since upgrading 12.10->13.04 beta.
Intel Sandybridge , dvi (1920x1080) and hdmi to dvi (1280x1024) output. Attempting to login to Unity with both monitors connected results in a hard hang - the desktop appears but is unresponsive and the launcher strip has purple hue instead of background tint (gray in my case). Connecting the smaller hdmi to dvi monitor after login works, but attempting to rotate the smaller screen in system settings then results in corrupted image on the larger fixed screen. Reversing the connections (big screen on hdmi to dvi, small screen on dvi) produces similar behaviour. xrandr --verbose with both screens attached is appended Running latest 13.04 beta, amd64. This setup worked fine in 12.10 with the smaller monitor rotated or not. ** Attachment added: "xrandr.txt" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1155568/+attachment/3647412/+files/xrandr.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1155568 Title: dual monitor support broken - regression vs 12.10 Status in “xserver-xorg-video-intel” package in Ubuntu: Expired Bug description: In 13.04 dual monitor support is broken in my setup (intel graphics dell latitute e6410) with external monitor.
