Manjaro KDE: Can't login, loging in tty works, no error displayed

tokr · 27 April 2022 15:46

Hi everyone,

today I have tried to log in to my Manjaro KDE laptop and got stuck in the login loop. After putting in my password I get a short glimpse of black screen and then I am back in login screen again. I can’t start any desktop session (wayland or X) or any other WM.

I am running Manjaro KDE on a laptop with nVidia 2060 graphics card. Yesterday, everything was running fine. I did not perform any update.

I have been making some changes to my .bashrc file yesterday. I have reverted that, but that didn’t lead to resolving my issue.

I am sure I am entering my password correctly. I have been looking around this forum for a solution to my problem, but didn’t found anything specific.

I can use Ctrl + Alt + F2 to access tty.

I have no idea how to resolve this issue. Any tip on what to do would be a tremendous help!

Furthermore, creating a new user and attempt to log in doesn’t fix the issue, so the root cause shouldn’t be a user configuration.

Any ideas?

in TTY run this command:
startx

tokr · 27 April 2022 16:42

I got in!

Now, how do I fix my situation to prevent repeating it?

brahma · 27 April 2022 16:43

try rebooting first and see if it happens again and select x11 instead of wayland in the log in screen

tokr · 27 April 2022 16:48

Both X11 and wayland sessions lead to the login loop.

Only way I can use my computer is to avoid SDDM, by going into tty, loggin in there and runing startx.

so it did happened again? probably a graphic driver issue… provide formated output from:
mhwd -l
mhwd -li

tokr · 27 April 2022 17:02

It happens to me every time I reboot or turn off my laptop.

Output of mhwd -l

Side note: I am using accessibility option to display desktop notification in KDE when I turn on the Caps-lock key. These notification have randomly an oversized window. also, my chromium browser in which I am writing this froze a few times, probably because of that. without caps lock it seems to hold.

you could try reinstalling your video drivers:
uninstall first nvidia drivers with:
sudo mhwd -r pci video-hybrid-intel-nvidia-prime
im not sure if you need video linux, but i have it installed and have the same setup as you, so try installing it:
sudo mhwd -i pci video-linux
reboot and check if you can boot without black screen

EDIT: if you using optimus manager dont run these commands!!!

tokr · 27 April 2022 17:10

I am not using optius manager. I have stopped using it after some other issues (not sure what they were to be honest).

I am using the DRI_PRIME env var whenever possible.

Does this have a influence on proprietary vs opensource drivers or not?

EDIT: Also, you are suggesting removing some drivers. Should I install them back again afterwards?

brahma · 27 April 2022 17:14

yes were reinstalling them, youll install them back again … but first provide also info from:
mhwd-kernel -li

tokr · 27 April 2022 17:19

i already ran sudo mhwd -r pci video-hybrid-intel-nvidia-prime

got probably a little unexpected output:

The following kernels are installed in your system:
   * linux515

is this ok? i was surprised by the nvidia-prime dependency … what should I do now? do the sudo mhwd -i pci video-linux, restart ad see how it goes?

brahma · 27 April 2022 17:22

well well, yes install the video-linux, reboot and see if you get stuck

tokr · 27 April 2022 17:27

After

sudo mhwd -i pci video-linux

and reboot the situation is still the same.

Can’t login through SDDM into both X and wayland.

brahma · 27 April 2022 17:29

ok so can you check logs with:
journalctl --boot -0 --no-pager

tokr · 27 April 2022 17:38

the output is extremely long. I put it in pastebin: dub 27 19:25:35 tomaskrulis-nitroan51554 kernel: microcode: microcode updated ea - Pastebin.com

I noticed something about sddm exit code 127. could that be something?

brahma · 27 April 2022 17:42

ok so you have these errors:
pcieport 0000:00:1d.5: AER: Corrected error received
i dont say thats what is causing your black screen, but it needs to be fixed… so first turn on your wifi and open the ksystemlog application and check if you have logs spamming there…

tokr · 27 April 2022 17:46

i have these

27.04.22 19:44	kernel	alx 0000:07:00.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, (Receiver ID)
27.04.22 19:44	kernel	alx 0000:07:00.0:   device [1969:e0b1] error status/mask=00000080/00002000
27.04.22 19:44	kernel	alx 0000:07:00.0:    [ 7] BadDLLP

and these:

27.04.22 19:44	kernel	alx 0000:07:00.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, (Receiver ID)
27.04.22 19:44	kernel	alx 0000:07:00.0:   device [1969:e0b1] error status/mask=00000080/00002000
27.04.22 19:44	kernel	alx 0000:07:00.0:    [ 7] BadDLLP

they are red and yellow (first time i am using this application so please bear with me). is that relevant or should i look for something specific?

edit: it runs ok, lot of spamming, if that was in question.

brahma · 27 April 2022 17:48

thats ok… and are there many of these messages in there?

tokr · 27 April 2022 17:49

Yes, roughly every second, in the default (no filtering) view.
