[SOLVED] My screen flickers sometimes

Framework Laptop 13 Linux
1

Sometimes, every few seconds my Framework screen flickers when I boot into any Linux kernel 6, but in kernel 5 it all works fine.

Details:

  • Linux Mint 21.1
  • I have removed all Cinnamon extensions
  • I have a dock (through a USB C) that has with one external monitor plugged into it
  • I have another external monitor plugged into the HDMI port
  • Neither of my external monitors flicker. Only the laptop screen flickers.
  • I’m currently running kernel 6.0.7-060007-generic
  • 12th gen Intel core processors

If I unplug a monitor and plug it back in, the flickering might stop.

Thanks.

First of: Welcome to the forums!

As for your issue, you can try this:

Screen flickering

Panel Self Refresh (PSR), a power saving feature used by Intel iGPUs is known to cause flickering in some instances FS#49628 FS#49371 FS#50605. A temporary solution is to disable this feature using the kernel parameter i915.enable_psr=0.

Yay! That fixed it. Thanks Anachron!

For the record, this is what I did:

  • I edited /etc/default/grub using “sudo nano /etc/default/grub” and added “i915.enable_psr=0” to the end of the GRUB_CMDLINE_LINUX_DEFAULT line.
  • I ran “sudo update-grub” to apply those changes.
  • I rebooted
  • I verified that

That’s it. Now I’m happy! :slight_smile:
