Black screen after gnome-login with cursor (only sometimes!)

DeutscheGabanna · 2024-03-07 19:05:55

Hi,

if this error was occuring every time, it might be easier to reproduce. But the black screen after logging in on gnome, with just an X cursor visible, occurs once per maybe 10 boots.
First - I obviously keep my packages up to date by running `sudo pacman -Syyu`.

Here's the `journalctl -p 3 -xb` from 3 past boots that includes one black screen occurence.

What might be the problem?

up to date by running `sudo pacman -Syyu`

Don't. Check the pacman manpage, understand what the second "y" actually does and how this can harm you and stop using it unless you *REALLY* mean to.

Here's the `journalctl -p 3 -xb`

Isn't really helpful.
The "p" is priority, it doesn't control the boot age, -x is flat out spam - never use this in support requests and while that looks like a system journal, run journalctl as root unless you're in the wheel or adm groups.

Please post your complete system journal for and affected boot:

sudo journalctl -b -3 | curl -F 'file=@-' 0x0.st

for three boots ago (if that was the intention)

Disable dhcpcd (though that's hardly the problem)
The journal has only one login into a gnome X11 session that ran for ~25m and has FF and steam running, so I assume that wasn't a "black screen" session?

remove /etc/X11/xorg.conf to not hav e it gloss over problems.

You're running nvidia 550xx w/ apparently nvidia_drm modeset=1 fbdev=1 (you're not using the kernel parameter but the simpledrm device isn't to be seen anywhere)
Try to add the "nvidia_drm.modeset=1" kernel parameter and remove fbdev=1, its status is currently inconclusive.

I encountered the same problem

"Activation request for 'org.freedesktop.nm_dispatcher' failed."
This is my last failure, I currently uninstalled networkmanager and continue testing

I did try that. Setting the modeset to 1 caused flickering issues in games. I suspect it may be because the games started running in Xwayland mode and my Nvidia GPU does not work well in this mode. Returning to X11 and no modeset removed this problem.

Removing the fbdev=1 proved to be harder. I cannot find for the love of me any file that sets it. I searched in /etc/modprobe.d/ and there is no mention of it:

$ cat /etc/modprobe.d/*
blacklist nouveau
options nvidia NVreg_PreserveVideoMemoryAllocations=1
options snd_hda_intel power_save=0

A kernel parameter is never set in modprobe.d but in the configuration of your bootloader: https://wiki.archlinux.org/title/Kernel_parameters

I stumbled on the problem once again and have prepared two journalctl files - one with a successful boot & login and the other where there's a black screen.

Successful: http://0x0.st/XoWc.txt
Failed: http://0x0.st/XoWT.txt

That's the SIMPLYDUMB device, enable https://wiki.archlinux.org/title/NVIDIA … de_setting - use the "nvidia_drm.modeset=1" kernel parameter (modprobe.conf won't do!)
