Desktop delay after logging in

Help

Hello everyone,
Recently, after logging in, there has been a slight delay of a few seconds during which the screen is completely black. The mouse works, and I can launch applications using SUPER+W (e.g. console or Firefox), but the rest of the desktop, i.e. the wallpaper and app dock, appear after a few seconds.

I would like to investigate the problem and the delay to understand what it might be, but I have no idea which tools and logs to use.

I use openSUSE Tumbleweed, and the last major change I made to my setup was to /etc/fstab, where I added some NFS volumes that mount correctly and without errors.

Thanks to anyone who can help me understand the problem.

You can try reverting your fstab change and see if that fixes it. To be frank, I’d put my money into exactly this. Maybe Plasma is waiting for something to open and look at your NFS volumes.

Otherwise, take a look at your journal and see if there is anything indicating the system is waiting for something to happen before the desktop shows. You can see the messages of the current boot with

journalctl -b 0

To see the messages in your user session (this is where most of your KDE stuff will run), use

journalctl –-user -b 0

If you don’t like scrolling down to the end to read the messages backwards, you can pass the -r flag to have the messages be sorted in reverse.

thanks!
you helped me fix some errors.

The other thing I did is to enable/disable

Settings > Global Theme > Splash Screen

and now looks fixed.
In the logs there are were issues related to ksplash:

Oct 07 12:34:39 localhost.localdomain systemd[1840]: Started dbus-:1.2-org.kde.KSplash@0.service.
   * Oct 07 12:34:42 localhost.localdomain systemd[1840]: Starting KSplash "ready" Stage...
   * Oct 07 12:34:42 localhost.localdomain systemd[1840]: Finished KSplash "ready" Stage.
   * Oct 07 12:35:39 localhost.localdomain plasma_waitforname[2894]: org.kde.plasma.waitforname: WaitForName: Service was not 
     registered within timeout
   * Oct 07 12:35:39 localhost.localdomain systemd[1840]: dbus-:1.2-org.kde.KSplash@0.service: Main process exited, 
     code=exited, status=1/FAILURE
   * Oct 07 12:35:39 localhost.localdomain systemd[1840]: dbus-:1.2-org.kde.KSplash@0.service: Failed with result 'exit-code'.

I guess this is the default behavior when it’s disabled.
