Dmesg

I'm no longer able to select 16:9 resolutions (I was previously)

I've tested this on both modesetting xf86-video-intel

Here's the output of xrandr:

I'm not sure how long this has been broken for - I don't change resolutions often, but I did notice I couldn't change to 1080p or 720p on the new Unigine Superposition benchmark

Comment 4 Mike Lothian 2017-04-18 06:48:27 UTC 
Re-reading what I've posted above, xf86-video-intel and xf86-video-modesetting are giving different results
Comment 5 Mike Lothian 2017-06-20 13:46:31 UTC 
xf86-video-intel gives the correct resolutions the built in xf86-video-modesetting (xorg-server 1.19.3) gives a different set of resolutions. There has also been "flashing" when using this ddx
