Question for GNOME3 users

[pjsf]

Last week on Manjaro I got a whole stack of updates to GNOME and some system packages. After rebooting, both gdm and GNOME give me black screens with cursors, journalctl /usr/bin/gnome-shell gives me a bunch of errors: 

Code:

Failed to open gpu '/dev/dri/card0':        
GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Operation not permitted

Installed Budgie a little earlier to get another DE going, and to see if it'd run since it shares a lot with Gnome. It runs without any issue.

Have any other GNOME3 users experienced similar issues from the most recent updates?

You can try adding yourself to the video group:

Code:

sudo usermod -aG video USERNAME

then restart.

Nah, doesn't do it.  I've also had a go at a fresh install of the new 20.02 image which does suggest video as one of the default groups, still no kind of Gnome.
