Title:
Xorg does not detect displays in rootless mode on nvidia proprietary
drivers (GNOME)
Status in NVIDIA Drivers Ubuntu:
New
Status in mutter package in Ubuntu:
Confirmed
Status in xorg package in Ubuntu:
Confirmed
Bug description:
There are two bug reports in LP: #1559576, LP: #1632322 and also LP:
#1666664, where GDM does not start on proprietary nvidia drivers. As
it turned out, the reason for that was Xorg starting in rootless mode
and apparently not initializing everything properly, which was causing
gnome-shell/libmutter to crash.
Installing xserver-xorg-legacy did partially fix those issues.
Enabling modesetting for nvidia driver however still causes the
problem.
Here are some parts from log:
