Hi, I seem to be having a problem with X11 on my Chromebook C201 Parabola system.

I was playing around a bit with some of the X11 drivers yesterday, which included updating mesa. Now, lightdm won't load up properly and I am seeing the following in my /var/log/Xorg.0.log:

It seems that glamoregl is failing for some reason ('couldn't get display device'?). Any ideas how I can fix this? I have tried re-installing mesa, xorg-server, libglvnd.
