[PROBLEM] Sometimes hangs(stuck) when booting on the splash screen after login (login screen appears twice)

The described problem appeared not so long ago. After installing the 5.9 kernel, I noticed that sometimes the system doesn’t boot and the boot process freezes on the splash screen.

Sequence of actions:

  • turn on the laptop
  • when loading, select the kernel 5.9
  • I see lines of text appear on the black screen
  • a password entry window appears
  • I enter my password and press Enter
  • again I see lines of text appear on the black screen
  • the login and password window appears AGAIN
  • I enter the password AGAIN and press Enter
  • the SplashScreen appears
  • the system doesn’t respond to anything else
  • sometimes the mouse cursor appears, but the system also does not load further than this screen

The Ctrl+F2 key combination works and I can log in, but it doesn’t help.

If I press Ctrl+Alt+Del, a choice of actions appears - restart, turn off, and so on. But this screen with a choice of actions does not look like a normal one - it does not have a background image and the buttons are on a black background. In addition, the buttons on the screen do not respond to the keyboard and mouse.

The problem only occurs on the 5.9 kernel.

there ares theses links topics
https://bbs.archlinux.org/viewtopic.php?id=257449
https://wiki.archlinux.org/index.php/NVIDIA_Optimus#Use_NVIDIA_graphics_only

be careful with kernel5.9 and nvidias drivers ,
can this working with 450xx series ?

#5

I don’t want to make such changes (use Nvidia only), it might cause problems, and I need my laptop for work.
What could be the problem? Maybe I should issue a bug report for KDE or SDDM or smth else?

#6

can you provide

sudo mhwd -li

this point in log is to good

I plan to try going back to the 450 driver and see if the login problem remains. Should I do this?

#9

or try with 450xx series

#10

I reinstalled SDDM and 455 Nvidia driver … so far, the problem has not appeared again, I hope that this helped. If so, then it’s some kind of magic :smile:

#11

It didn’t help. The problem appears even on the 450 driver and the 5.9 kernel. And after last SDDM update too. But now it just freezes after entering the password and pressing Enter.

I created an issue for SDDM: Hang on login screen · Issue #1330 · sddm/sddm · GitHub

Any other ideas?

#12

sometimes I have the same problem, look at this Login screen freezes, could not connect to display startx works for me.

#13

I installed Manjaro today and am having the same problem. During the black screen I get

Failed to start Load/Save Screen Backlight Brightness of backlight:acp_video0

&

Failed to start Load/Save Screen Backlight Brightness of backlight:amdgpu_bl1

and on the second login screen I get to splash screen where it loads and gets stuck and my cursor is on screen and can be moved. Using safe mode worked for me though

#14

I had the same problem with kernel 5.8.
I installed kernel 5.4. LTS and this problem didn´t occur anymore.

#15

Got tired of it, I did a fresh install, just updated system, install programs, and so far it’s working ok. It seems like its a kernel problem, just like Keruskerfuerst said . We’ll have to wait unil 5.10 becomes stable, 5.4 doesn’t work with my laptop.

#16

Unfortunately, my laptop will not work properly on kernel 5.4.
Let’s hope that this bug will be fixed soon.
Could it be a KDE problem?

#17

Have you tried this? Problems when using nvidia non-free driver I did that change in the grub, and the failed to start doesn’t appear anymore.

#18

I don’t think so, I had xfce the first time I commented the previous post.

#19

Ah, ok.
Thanks, @guillopacheco ! I had already changed this line before (acpi_backlight). But I used the ‘vendor’ value, now I put ‘video’. I updated the grub and the system booted normally.
Let’s see what happens. The problem doesn’t always show up, I’ll test it.
