For the past week or so, Ubuntu 20.04 randomly freezes (3 or 4 times a day) on my Dell XPS Developer Edition laptop. All I can do is hold down the power button to manually turn off the machine and then restart.
There are no logs in /var/crash
and running
journalctl -b -1 -e
doesn't reveal any logged info - the last logged item is about 10 minutes before the crash.
I also installed sensors and was monitoring the temp yesterday while working. When a crash happened the temperature was normal (about 40.0°C on all cores).
All software is up to date.
Each time it crashes I'm doing something different. The only common program I (probably?) have open is Chrome though I'm not completely sure, it's just a guess because I almost always have it open.
Any help is appreciated. 18.04 rarely crashed and 20.04 was fine at first but several months after upgrading here I am...
