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:/
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_CMDLINE_
-----
Is now:
-----
GRUB_CMDLINE_
-----
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.
