I have a Dell G7 15 7590 laptop. I recently installed Ubuntu 20.04.

Now one to two times a day the computer freezes. Sometimes it comes back and sometimes I think a full restart is required.

cat /var/log/syslog shows:

Each time it freezes there are similar messages in /var/log/syslog

There almost are are messages from iwlwifi before and after the crash whcih makes me wonder if that is part of thie issue.

I tried every suggestion in this thread and nothing worked.

I see other issues have been raised here on Launchpad and here on the Arch Linux forums

There are no issues with this laptop when running Windows and the laptop is brand new so I do not think it is a problem with the thermal paste or hardware issues.

I am almost always running the Chrome browser, but it does not seem tied to anything specific (i.e. CPU intensive tasks or GPU intensive tasks) and it has happened when I am not running Chrome as well.

Does anyone have any suggestions for me to try?

I have tried to run this with the nVidia 440 driver and the Nouveau driver and it happens in both circumstances.

For more information, I looked and noticed that there was no thermal-conf.xml in /etc/thermald

I created that file with contents from this post but the server seems to be freezing (just less often).

Can somebody tell me:

  • What settings would help thermald
  • Why there was no configuration file and what I can do to make it work correctly?

I'd like to avoid this throttling and crashing at all costs.
