Experiencing frequent crashes on Regolith 3.2 and Ubuntu 24

[bkjohnson]

A few weeks ago I installed Ubuntu 24 as a clean install and then installed Regolith 3.2. Since then I've been getting frequent crashes, often 2-3 times a day. I haven't noticed a specific pattern to them other than it seems to happen as I'm doing something, such as typing, and when it happens the only option I have is to log out. I'm not really sure what log files would be useful but I'm happy to provide some. Right now I don't think I can predict when I'll get a crash, so I'm not sure where to begin troubleshooting.

Here is what I see when it happens - it covers the full desktop:

Same here. Any updates?

Same... I'm having some messages in my dmesg.

It seems to happen when I'm away from the laptop and session tries to lock itself

For me the trigger seems to be shutting down a rails server. I can Ctrl + c, let it gracefully shut down, but then whatever I do next will result in the crash. Even just switching to another workspace.

Sorry don't have any fixes to provide unfortunately. Often these kinds of issues can be associated with some graphics hardware/driver combo. FWIW I have found Regolith to be very stable using intel and amd integrated graphics, as well as discrete Radeon 6xxx and 7xxx cards.

Of course, your issue may not have anything to do with that, just a guess. Hopefully a solution emerges..

I'm having that issue and I have documented somethings in here: https://bugs.launchpad.net/ubuntu/+source/gnome-flashback/+bug/2086706

It happens often when the laptop is idling.

Current work around is having "caffeeine" running to prevent laptop to logout/sleep/something that triggers the crash
