Comment 62 for bug 1879633

Hi,

I installed Ubuntu 20.04.1 LTS on my XPS9310.

Enabled developper updates:

with
deb http://ch.archive.ubuntu.com/ubuntu/ focal-proposed main restricted universe multiverse

and then followed these instructions:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1879633/comments/43

after reboot the wifi was detected.
Unfortunately this is not stable and crashes either immediately or after a few minutes of usage.
And usually the laptop freezes after a while and becomes very very hot.

Here the kernel logs
