Hi - Installed OpenSUSE Leap 15.4 from scratch. While I can’t confirm the exact order, I believe the initial graphical login after install was fine. However, I then used Yast to install the proprietary NVIDIA driver for my older laptop. That went fine. However, while I can’t be certain the issue started after this, I think after this the first time I login graphically my password is accepted but eventually without starting the desktop ,it returns me back to the graphical login window. I simply enter my password in again and then all is fine after that. I then noticed in my Xorg.0.log.old the following suggesting there is at least on the initial login a problem with the NVIDIA driver. Here’s the relevant lines from the log file. Any ideas? Thanks.

If the proprietary NVIDIA driver is segment faulting on your older Laptop then, that’s it.
Fatal server error:
36.369] (EE) Caught signal 11 (Segmentation fault). Server aborting
- A quick explanation – a “Segment Fault” occurs when something (often a driver) attempts to access memory which is not available – either the memory address is out of range or, the protection on certain parts of memory has denied the attempted access.
In your particular case, there is memory associated with the GPU which, for the case of an older Laptop, may not be sufficient for the newest proprietary driver.
- What happens if, you were to use the open source “nouveau
” and “modesetting” drivers?
Thanks very much for the response. WIth Leap 15.3, I had poor performance with Nouveau and so went with NVIDIA proprietary driver and had much better success and it was stable. Since my initial post, ,I discovered that if instead of logging in graphically, if I go to another character based window and login in as myself and then run “startx” it comes up immediately and is fine. I the exited out, rebooted and I no longer have the issue with the graphical login. Very strange but I’m happy. I though it might be a one off so rebooted and tried directly logging in from the graphical login and again, it works fine. And I had rebooted numerous times before this and it always failed the first time. No idea why that resolved it but it does seem to now be resolved. Thanks again for the offer to help.
Well, I was wrong. The issue had nothing to do with startx. The problem will again occur on the graphical login. The issue appears to occur when I have the second monitor plugged in. Accessing KDE works fine if I login from one of the tty windows (ALT-F1) and run startx. All is well. If I log off (not even reboot) and then login via the graphical login (ALT-F7), it will fail as described above the first time. It then returns to the graphical login window and if I do nothing but enter my password again, it logs in successfully. If I keep the second monitor unplugged while doing the graphical login until after the kde screen appears, then I can plug it back in and all is well again. This setup used to work perfectly on LEAP 15.3 utilizing the NVIDIA proprietary driver. The change was I went to Leap 15.4 and now I have this minor (but annoying) issue. Any more ideas? Thanks.

Those “Multiple” lines apparently result from some process that doesn’t know how to not count symlinks and the files they point to twice. /opt/kde3/share/config/kdm/ is symlinked to /etc/kde/config/kdm/ for admin convenience.
Two equal Nvidia mobile video cards in a laptop?! Without Intel or AMD builtin GPU?!
Is it possible?
Try to debug it with using LiveISO or installing OS on another drive.
