Switching to another already logged in user (Ctrl+Alt+F#) takes a long time (approx. 10 - 20 seconds).

First, the screen turns black, after some seconds the cursor appears, and then after some time the desktop appears. Sometimes the icons and text is scrambled which can be fixed by resetting Gnome (running r from Alt+F2).

How can I eliminate this annoying waiting time ??

I have Nvidia Geforce GTX 1060 TI with current nvidia driver from standard repos.

Same setup using VGA cable works fine, it is the same issue for different monitors (one is Full HD and one is 4K).

I found a similar question, but it is very old and has a different setup and it has no suitable answers.

Installed driver:

  Installed: 418.56-0ubuntu1
  Candidate: 418.56-0ubuntu1
  Version table:
 *** 418.56-0ubuntu1 500
        500 http://de.archive.ubuntu.com/ubuntu disco/restricted amd64 Packages
        100 /var/lib/dpkg/status

Output of sudo lshw -C display:

       description: VGA compatible controller

This is the output from journalctl -xe when switching: https://pastebin.ubuntu.com/p/9vYPKjG6DJ/

/var/log/Xorg.0.log doesn't print anything when switching.

I did not change anything from default settings regarding graphics.

  • Please add output of the command sudo lshw -C display to Your question. We need to know what kind of nvidia driver is in use. – Michal Przybylowicz Sep 5 at 12:46
  • @MichalPrzybylowicz I updated the question with that information. – pLumo Sep 5 at 16:21
  • Is there anything in the logs right after the switching in journalctl -xe or /var/log/Xorg.0.log ? – Michal Przybylowicz Sep 5 at 16:42
  • @MichalPrzybylowicz added output of journalctl -xe. – pLumo Sep 5 at 17:41
  • This issue is fixed for me in Ubuntu 19.10. +happy+ – pLumo Oct 23 at 15:12

From Arch Linux: Slow loading of system icons/slow GDM login

# gdk-pixbuf-query-loaders --update-cache

Running the aforementioned command may also fix repeated occurrences of the "Oh no! Something has gone wrong!" error screen and/or very slow loading and login with GDM as described in the following forum thread.

The above is a tiny fraction of the Arch Linux link and other useful tips / things to try can be found there.

  • I get gdk-pixbuf-query-loaders: command not found. Ubuntu mapage says it is provided by libgdk-pixbuf2.0-bin, but that is installed (libgdk-pixbuf2.0-bin is already the newest version (2.38.1+dfsg-1).). – pLumo Sep 12 at 15:45
  • A reinstall of libgdk-pixbuf2.0-* and a dpkg-reconfigure for these packages didn't help. – pLumo Sep 12 at 15:52
  • Actually might have to reinstall extension: askubuntu.com/questions/1154929/ubuntu-19-04-stops-working – WinEunuuchs2Unix Sep 12 at 17:32
  • That did not help – pLumo Sep 12 at 17:44

This issue is totally fixed for me after upgrading to Ubuntu 19.10.
Not sure, but it might have been related to this issue:
