Login screen doesn't show after recent update

Support Graphics & Display
1

Hi everyone, I use Manjaro with Xfce on my desktop computer and after a regular update some weeks ago, the login screen stopped showing up when I boot. So, the system is basically unusable since then.

I was able to get a command line using Ctrl+Alt+F2. From there I ran a complete update with pacman -Syyu and I also installed the newest kernel with mhwd-kernel -i linux610. However, this didn’t change anything.

I had the same problem after Manjaro update on my Samsung laptop. There the login screen also didn’t show up. But only sometimes, and after a system update, it now works again on the laptop. But as I said, doing an update didn’t help on my desktop computer.

I also tried to boot using different kernels installed on the system, but the issue is the same for all of them.

I read some seemingly related posts and tried journalctl restart lightdm. But this just gives me a black screen with an underscore in the top left corner.

Finally I also tried startx from the command line, but this quits with an error: “no screens found”.

I was able to boot from the USB stick that I used to install Manjaro. With that I was able to get a GUI, so there should be no hardware issue. From this system I was also able to get a command line for the installed system with manjaro-chroot -a. But I don’t know how this could help.

I’m not a linux expert and completely stuck. Can somebody help me to repair the system? Thanks in advance!

PS:
The desktop computer has a NVIDIA GPU. I recall reading somewhere that the issue could be related to the GPU drivers.

Hi @mts,

Well, the chroot can help because there you can find out why it’s not working. That’s what the logs are for, after all. So please provide the output of the following, when tun in the chroot environment:

journalctl --priority=warning..crit --no-pager --boot=-1

Where:

  • The --priority=warning..err argument limits the output to warnings and errors only;
  • and the --no-pager formats the output nicely for use here, on the forum;
  • the --boot=-1 argument limits the output to log messages from the previous boot. This can be adjusted to -2 for the boot before that, -3 to the boot before that, and so on and so forth.

:bangbang: Tip :bangbang:

When posting terminal output, copy the output and paste it here, wrapped in three (3) backticks, before AND after the pasted text. Like this:

```
pasted text
```

Or three (3) tilde signs, like this:

~~~
pasted text
~~~

This will just cause it to be rendered like this:

Sed
sollicitudin dolor
eget nisl elit id
condimentum
arcu erat varius
cursus sem quis eros.

Instead of like this:

Sed sollicitudin dolor eget nisl elit id condimentum arcu erat varius cursus sem quis eros.

Alternatively, paste the text you wish to format as terminal output, select all pasted text, and click the </> button on the taskbar. This will indent the whole pasted section with one TAB, causing it to render the same way as described above.

Thereby increasing legibility thus making it easier for those trying to provide assistance.

For more information, please see:

:bangbang::bangbang: Additionally

If your language isn’t English, please prepend any and all terminal commands with LC_ALL=C. For example:

LC_ALL=C bluetoothctl

This will just cause the terminal output to be in English, making it easier to understand and debug.

Hi @Mirdarthos, thanks for your answer!
I ran the command with boot=-2 and got the following output

[manjaro /]# journalctl --priority=warning..crit --no-pager --boot=-2

I’ve heard that this is fine:

But I’ve removed mine:

$ mhwd --listinstalled

Warning: No installed USB configs!

So try and remove it to see what happens:

sudo mhwd --remove pci video-modesetting

Also, while we’re at it, let’s force-reinstall the nvidia driver:

sudo mhwd --force --install pci video-nvidia

Reboot and see if it worked. If not, boot into a chroot environment, and re-run and provide the output for the logs as before:

journalctl --priority=warning..crit --no-pager --boot=-1

The second command to force-reinstall the nvidia driver failed with

Well, there’s your problem.

Linux kernel 6.7 is EOL and has been removed. I’m thinking the update didn’t even complete. Please provide the output of:

mhwd-kernel --listinstalled
9

The output is

[manjaro /]# mhwd-kernel --listinstalled
Currently running: 6.1.12-1-MANJARO (linux61)
The following kernels are installed in your system:
   * linux61
   * linux610
   * linux66
   * linux67
   * linux69
10

Why TF do you have that many kernels installed? I say remove them all except 6.1 and 6.6.

sudo mhwd-kernel --remove linux610 linux67 linux69

And then try reinstalling the driver again:

sudo mhwd --force --install pci video-nvidia
11

Is there a reason why not keeping 6.10 but the older ones? I usually get a system message “new kernel available” asking me to install it…

12

I recommended the older ones because:

  • 6.6. is the latest LTS as far as I know; and
  • 6.1. is the latest SLTS and will be maintained for 10 years:

That the thing. Just because you can do something doesn’t mean you should do it.

Unless there is a specific reason you need a newer version, like a feature or something, I say stick with the SLTS.

Of course, it is your choice, but as you can see if you stick with what you currently do, you have to be more attentive to what’s going on.

Wen you use Manjaro, kernel management becomes a thing, and you have to pay attention to them, what’s installed and what’s happening. Because it matters.

Thanks for the explanation! Then it’s a bit unfortunate that this system message goes like “please update!”, sounding like this should really be done.

14

I haven’t seen that message in more than, what, 3 years? But I don’t remember it said that. I think it only mentioned that there was an update that can be installed. Of course, I might be wrong, since I last saw it many moons ago. But to be fair, that is kernel management on your own machine.

15

It’s Manjaro Settings Manager and says: “Newer kernel available, please update.” This notification will pop up after every start unless you update. I guess this can be disabled somewhere, but I have the default… (EDIT: In Manjaro Notifier Settings)

Back to topic: The operation was a success! I reinstalled video-nvidia and rebooted - and now it worked! I got a login screen, was able to log-in, and also my GPU works fine.

Thank you so much for your help!
