Title:
modesetting driver unbearably slow
I saw your reference to the log from #2 and took a deeper look at it,
and saw this line:
[ 76855.829] (**) modeset(0): Option "AccelMethod" "glamor"
In my xorg.conf, I had Option "AccelMethod" "None" and hadn't thought
too hard about it because graphical acceleration worked with it set to
"None"
Hmm, maybe not. The log from the original reporter in comment #2 does
not show the same messages.

I ran into this issue as well, and switching from the modesetting driver
back to the intel driver in xorg.conf has helped tremendously. I went
from 15.10 through 16.04 (which was entirely broken for me, something
involving compiz I think) to 16.10, which worked, but had terrible

If gdm runs with user permissions how does/should Gnome Shell get access
to /dev/dri/* etc?
I assume it's not broken for everyone...

Alright then...
Does gdm let you log in to Unity7 (is it installed)? If so try that and
see if it's any smoother (which would make part of the problem the Gnome
compositor).

Is it translucent or solid coloured?
