Description dmrickert 2015-06-16 17:17:08 UTC 
When changing the resolution from the native display, the screen goes black and does not revert to the last setting.  At this point, a reboot is required to fix it.

I have tested on multiple Macbooks, if it does not have an NVIDIA graphics card than there is no problem.  I'm booting 14.04 off of a USB stick and using the Nouveau drivers.  I've seen this with both the 3.16 and 3.19 kernels.

Steps to Reproduce:
-On a MacBook Pro with hybrid graphics, boot into a fresh Ubuntu 14.04 installation with kernels 3.16 or 3.19.
-System Settings > Displays > Pick a new resolution

Also happens if you use xrandr from the command line.

Additional Information:
