Josh Cogliati, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal as it will automatically gather and attach updated debug information to this report: apport-collect -p xorg 1398840 Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information. As well, given the information from the prior release is already available, testing a release prior to the development one would not be helpful. Thank you for your understanding.

I have two thunderbolt connected displays (one on a minidisplay port to dvi connector, and the other on a mini displayport to vga connector). If I plug only one in, it works. If I plug both in at boot up, than one of them will work randomly, and the other will not work at all. xrandr -q only shows the working one: $ xrandr -q xrandr: Failed to get size of gamma for output default Screen 0: minimum 1600 x 1200, current 1600 x 1200, maximum 1600 x 1200 default connected primary 1600x1200+0+0 0mm x 0mm 1600x1200 77.0* I am using the kernel parameter nomodeset or video does not work at all.
