Public bug reported:
Tried doing a fresh install of Ubuntu 16.04 on my rig outfitted with an
HD 7850, and it crashes on boot due to my AMD card installed. When I
removed the AMD card I was able to boot into Ubuntu. AFAIK, the drivers
with Ubuntu should support this card even though it is older, and even
I'm incorrect and it isn't supported, xorg should probably fail more
gracefully than a segfault, thus the bug report.
Note that I wasn't able to even install Ubuntu in the first place
without modifying grub to set radeon.modeset=0 due to the black screen
issue. I believe this modeset might have been set when the crash
occurred. This issue is reproducible every time.

Thanks for your time in looking into this. Note that if the debug information
says intel graphics that's because I needed to remove my card in order to write
this bug report.
