Issue with getting passed login screen. Stuck in a loop

Support KDE Plasma
1

Good morning community.
I am experiencing an issue where when the system boots up and I get to the login screen, once entered the password, and this is correct, when I press enter it seems to go back to requesting the password and this happens endlessly.

The workaround to successfully log in is to open a tty2 by pressing CTRL+Alt+F2 and login in from there and then typing startx.

This successfully logs me in and I have do this every time.

Output below from:

Hello,

Make sure that in the Session option field you have X11 session selected and not the Wayland session. That can create that loop password with SDDM with Nvidia drivers and GPU …

Hi thanks for coming back to me. Running the following I get:

loginctl
SESSION UID USER SEAT TTY
2 1000 robin seat0 tty2
4 1000 robin seat0 tty2
c2 962 sddm seat0

following that I ran:

loginctl show-session c2
Id=c2
User=962
Name=sddm
Timestamp=Sat 2022-03-19 08:13:12 GMT
TimestampMonotonic=63846783
VTNr=1
Seat=seat0
Display=:0
Remote=no
Service=sddm-greeter
Scope=session-c2.scope
Leader=1204
Audit=4294967295
Type=x11
Class=greeter
Active=no
State=online
IdleHint=no
IdleSinceHint=0
IdleSinceHintMonotonic=0

Also results from info centre show the following in OpenGL (EGL)

EGL_EXT_platform_x11 EGL_EXT_platform_device EGL_KHR_platform_wayland EGL_EXT_platform_wayland EGL_KHR_platform_gbm EGL_MESA_platform_gbm EGL_NV_robustness_video_memory_purge EGL_WL_bind_wayland_display EGL_WL_wayland_eglstream Wayland platform: EGL_NV_robustness_video_memory_purge EGL_WL_bind_wayland_display EGL_WL_wayland_eglstream EGL_NV_robustness_video_memory_purge EGL_WL_bind_wayland_display EGL_WL_wayland_eglstream

So I am king of confused as it seem that the sddm session is using x11. Do I need to remove Wayland all together.

Apologies I am kind of a noob :slightly_smiling_face:

Thanks in advance

Hi @Deadlyhydra, and welcome!

Please provide the output of:

find /etc -name '*.pacnew'

Tip:

To provide terminal output, copy the text you wish to share, and paste it here, surrounded by three (3) backticks, a.k.a grave accents. Like this:

```
pasted text
```

This will just cause it to be rendered like this:

Portaest sed
elementum
cursus nisl nisi
hendrerit ac quis
sit
adipiscing
tortor sit leo commodo.

Instead of like this:

Portaest sed elementum cursus nisl nisi hendrerit ac quis sit adipiscing tortor sit leo commodo.

Thereby improving legibility and making it much easier for those trying to be of assistance.

Please edit your post(s) accordingly.

Hi thanks for coming back to me.

I am not entirely sure what happened on the last post and why it didn’t apply the outcome from the terminal as per 1st post.

Will keep you posted as soon as I able to run the cmd. (Currently in the middle of house work) :laughing:

That should not be necessary at all, just make sure the SDDM session is set to X11 in case you also have installed plasma-wayland-session.
Also, if you still have the .xinitrc in your home directory, it should have
DEFAULT_SESSION=startplasma-x11
hence also try from TTY with startplasma-x11 instead of startx … but see if sddm service is started.
When you got the time, provide the info requested here too

Much obliged!

Does this need to be run as Sudo by any chance?

It would clear the errors, yes. So please do:

sudo find /etc -name '*.pacnew'
10 
sudo find /etc -name '*.pacnew'                                                             
[sudo] password for robin: 
    ~ 

Should I expect for something to happen?

11

No, it looks fine. I just had similar thing some time way back when, and I read something that unmerged .pacnew files could cause it. But yours look fine to me, so I don’t know what else can cause it.

12

So, even after latest update, the issue is still persisting?
