No external monitors after upgrade to 10.10

[Lee Colleton]

Binary package hint: xorg

My system now displays "Monitor: Unknown" for the main LCD and will not detect external monitors correctly. I have tried with both an external monitor and a projector which were previously working before the upgrade from 10.04

I am also unable to enable mirrored or external only display using the Fn+F7 toggle.

thank you for your bug report, can you configure your screens correctly using the xrandr command line option?

Please reopen this bug. It is still applicable after upgrading to 11.04

xrandr reports that only one display is available, I can't get the external display to work:

$ xrandr -q
xrandr: Failed to get size of gamma for output default
