Comment 17 for bug 1357804

A 29-inch LG 29um67-p with an on-board piece of legacy Radeon Sapphire 6670, don't work all together.

Ubuntu 16.04, max resolution in settings is 1920x1080. I try to manually include a 2560x1080 mode via xrandr, but after I apply a mode in terminal, the screen turns weird just like if I picked random digits for the resolution. Completely impossible to work.

Sad to see a bug was submitted almost 2 yrs ago, and seems no result yet. :/
