If you 'echo 6 > /sys/modules/drm/parameters/debug' then grab the dmesg after plugging in the external monitor that would be helpful. Also please attach the output of 'xrandr --verbose' with the monitor attached.

i had to downgrade to 12.10 but I observed problems also in clean install of 12.10. it worked before. after a few tries I was able to see both monitors and it's ok, but I;m not sure if it will work with the next reboot.
attached is the output of xrandr --verbose.

Also at this point it is more useful to do driver testing on raring, then we have a chance to fix it before release.

xrandr.txt Edit (7.3 KiB, text/plain)

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.

Aha - if I switch outputs to dvi (1920x1080) and vga (1280x1024) the problem disappears......

So, a combination of hdmi and dvi dual monitor output is causing problems on this setup.
