I'm experiencing random freezes while using my Ubuntu installation in a MSI GF75 computer, with Windows 10 in dual boot. This kind of freezes avoids me to use any key or the mouse, and stops the sound, forcing me to hard reboot my computer, since it doesn't unfreeze after a long period of time. There isn't likely a pattern for this to occur, since I was doing different things in different freezes. I tried to check the output of
journalctl -b -1 -xe
just after rebooting, but I don't find anything suspicious. The computer comes with a NVIDIA GeForce RTX 2060, which I think has the latest drivers since I used
sudo ubuntu-drivers autoinstall
to keep them updated. Also, it doesn't seem to be a problem with temperature, since
sensors always give me a temperature below 40 celsius, and this problem doesn't happen in Windows (which is more exigent), which makes me think that is a software problem related with Ubuntu. By the same reason, I don't think that is a problem with the RAM memory or with SWAP, but I could be wrong. If you need the output of any command let me know. Thank you for your help!
