Title:
Screen randomly turns black minutes after successfully login with GDM
Status in gnome-shell package in Ubuntu:
New
Bug description:
Hi, Daniel van Vugt asked me to fill a new bug for the problem I have
after he replied me in this old problem with GDM.
https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1705369
First, I will show the basic configuration of my desktop computer:
-Motherboard: ROG STRIX X370-F GAMING.
-CPU: Ryzen 7 1700.
-GPU: GTX 1050 2GB from MSI.
-Sound: Xonar DSX with ALC1220 of the motherboard deactivated.
Well, the problem I have ocurrs randomly and I saw it in Ubuntu 17.10
and 18.04. In the prior version I get the typical “stopping user
manager for uid” message, but in the most recent version I only see
some information about storage I always see in the system boot,
nothing apparently bad. I always use the official NVIDIA blob driver
from the Proprietary GPU Drivers PPA, but the I also saw the bug in
drivers provided by Ubuntu’s repositories.
I used Linux Mint 19 for one month and I didn’t see the bug, so I
think that origin is from Ubuntu’s stack. I suspect of two components
and three possibilities:
-GDM.
-NVIDIA Prime.
-Both combinanted.
I’m trying a workaround setting nomodeset in the file
“/etc/default/grub”. The line:
-----
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
-----
Is now:
-----
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
-----
After modify the file I executed the “sudo update-grub” command.
Until now I didn’t see the bug again, but it’s too early to make sure.
If I don’t see the bug again in two months I will declare the bug
solved for me, but this is not the "out of the box" behavior you
expect from a system like Ubuntu.
Sorry if my English is hard to understand.
