Recently my laptop (details below) running Ubuntu 24.04 has started logging me out without warning The screen freezes for about 30 seconds, then goes blank, and finally I'm shown the login screen. It's happened when running IntelliJ, or Audacity, or just browsing with Firefox Sessions can go on for hours, or end after less than 30 minutes What can I do to trace this issue?

There's three files in the /var/crash/directory

  • usr_bin_gnome-shell.1000.crash (51MB binary file)
  • _usr_bin_gnome-shell.1000.upload (empty)
  • _usr_bin_gnome-shell.1000.uploaded (37k text file - "ba98a3b4-182d-11ef-8b80-fa163ec8ca8c")

uname -a gives this

Linux my-laptop 6.8.0-31-generic #31-Ubuntu SMP PREEMPT_DYNAMIC Sat Apr 20 00:40:06 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

lsb_release gives this

No LSB modules are available.

** Update ** This is happening again. I can reproduce this every time with the latest release of eclipse. If I open Eclipse, and move a tab, then the screen freezes, eventually goes black, and then the login screen is displayed So far, this is the only application that causes the logout

    Please edit your question and add details about your hardware (CPU, RAM, free space on the partition Ubuntu is installed on) and add details whether your system has a swap file - if yes, which size - or not.

  • Look in /var/crash for .crash files that match the times of these desktop crashes (logouts)

    @JosephMcCarthy : sorry for the confusion - it should say "... so this should not be the reason". I forgot the write the "not" in my previous pst.

    My ubuntu 24.04LTS XP64 Gateway laptop will occasionally suddenly freeze, go to black screen for a few minutes, then ends up at login screen - seems to happen if I don't let it 'stabilize' before over-tasking it like at boot up... have to give her extra time to 'settle-in' before zooming off w/browser. I'll watch HDD access light and wait until it finishes it's wake-up ~ play nice ;-)

Reset to default

I made a workaround changing the Exec attribute from my eclipse.desktop to this:

Exec=env GDK_BACKEND=x11 /my/home/to/eclipse/executable
