Bug Description
[Impact]
GLX is missing. gnome-shell visible latency is very high with Xorg 2:1.20.4-1ubuntu1. And reinstalling the previous version (2:1.20.3-1ubuntu1) seems to fix it.
[Test Case]
$ glxinfo
Expected: Lots of information
Observed: An error
- or -
1. Log into a gnome-shell Xorg session ("Ubuntu").
2. Drag a window around in circles by its titlebar.
Expected: The mouse pointer to be somewhere near the titlebar
Observed: The mouse pointer is a long way away.
[Other Info]
Crucially, my patches to mutter's clutter-
[Workarounds]
* Install Xorg 2:1.20.3-1ubuntu1 instead; or
* Use Wayland sessions only.
