Ubuntu freezes and logs out

[Zhivko Stoimchev]

Ubuntu FREEZES every day. Brave and WhatSie are oppened, Spotify plays in background. I have external display, and I disconnect the HDMI. Ubuntu FREEZES, and logs out. All sessions are lost, what I was doing online in Brave. If is frustrating. My display is 2880x1800, and I use fractional scaling because my external monitor is 900x600 or something like that. With 23.10 I had NO PROBLEMS AT ALL. After installing 24.04. this happens EVERY DAY.

STEPS:
- disconnect HDMI
- expecting to use only laptop screen
- ubuntu freezes and logs out

THIS IS PROBLEM.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:

1. Run these commands:
    journalctl -b0 > journal.txt
    journalctl -b-1 > prevjournal.txt
and attach the resulting text files here.

2. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

3. If step 2 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us.

Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself.

I think most likely this is bug 2050865.
