Intermittent freezes/hangs - Fedora Linux 38 on Thinkpad X280
Raw
README.md

It appears that the random intermittent freezes every few minutes where the desktop/apps/pointer is unresponsive for a second or more is not limited to Fedora or Thinkpad.

The reason is likely Intel i915 GPU.

I found a discussion on Reddit that documents a solution in parts spread out over several comments for the complete answer:

https://www.reddit.com/r/thinkpad/comments/rhbf8m/solution_thinkpad_short_freezes_on_gnulinux/

Documenting the steps/files below for next time I'm in the same situation.

Edit /etc/default/grub:

5a6
> GRUB_CMDLINE_LINUX_DEFAULT="i915.enable_psr=0 psmouse.synaptics_intertouch=1"
8c9
< GRUB_ENABLE_BLSCFG=true
---
> GRUB_ENABLE_BLSCFG=false
  • i915.enable_psr=0 to resolve the hangs
  • psmouse.synaptics_intertouch=1 to improve touchpad functionality
  • GRUB_ENABLE_BLSCFG=false to ensure Fedora boots up

Run the following commands to update grub config and reboot

sudo mv /boot/grub2/grub.cfg /root/boot-grub2-grub.cfg.bak
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
sudo reboot
