Bug#770885: lightdm suspend issue with buster
I just installed 2 different laptops with the Debian Buster installer
(testing).
Both are using XFCE+ligthdm+NVIDIA gforce (with driver from the
nvidia-driver package).
In both laptops, if I suspend the session and try to get it back (for
example, by closing the laptop lid) all I will get is a black screen.
I have to manually restart lightdm in a tty.
I've scanned lightm/xorg/syslog/dmesg for clues, segfaults or whatever,
but I don't find anything relevant.
Please, advice, how to provide useful data related to this bug.
Anyway this was present in /var/log/lightdm/seat0-greeter.log. Not sure
if even related to the suspend mechanism:
