Linux Mint Cinnamon 22 fresh install screen issues (SOLVED)

Linux Mint
22

Thank you Howard!
I’m testing out the recommended Grub change now.
I changed /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT=‘quiet splash’
to: GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash i915.enable_psr=0 i915.edp_vswing=2”

We’ll see…

Thanks again!
Jim

ps. the second new parameter came after testing i915.enable change and still having the problem.
I found on your link: Linux Mint 22 screen flickering - Linux Mint Forums
and this:
For a flickering laptop display, you can try the turning off the panel self refresh by adding the kernel parameter i915.enable_psr=0 to grub. You can use the following information How to add a kernel parameter to temporarily or permanently add the parameter. When you add it temporarily, it adds it only for that current boot cycle, so if, for any reason, it seems to cause issues or it does not work, all you need to do is reboot to clear it. If you need more details than that topic provides, just let us know.

The second part of my change above came from:

These changes have NOT corrected the problem. :cry:

Have you tried what @easyt50 found?

intel_iommu=igfx_off

re-posting this link for convenience - very end mentions it
https://forums.linuxmint.com/viewtopic.php?t=426140

Scroll close to the end (#54-#56)- they have same solution until kernel is patched.

Still testing (it seems like a random, intermittent occurrence to me) but, I found this from the links that Howard and Joel sent and some other websites…
It appears to be a bug with Intel i915 and kernel 6.8.

Well, it’s been about 3 hours and the patch seems to be working great!!!

Here’s what I did (if someone doesn’t want to try to follow all of the links above):
Open etc/default/grub (as root).
Change the lines as I have below:

‘# GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash” modified by Jim 08/13/24’
GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash intel_iommu=igfx_off”

Save and close the grub file.
In the terminal:
sudo update-grub
( I did sudo update-grub2 also because I don’t know which one is really being used)

Shut down and reboot.

SPECIAL THANKS TO EVERYONE WHO LOOKED AT THIS!!!
This is a GREAT community!! You’re all my heroes!
Best, Jim

ps. (I’ll continue monitoring for awhile and if the issue doesn’t pop up again, I’ll mark this SOLVED! :grin:

Well, it’s been about 5 hours and I’m thrilled to report that both laptops are now free of the screen issue!! I’m marking this SOLVED!
THANKS AGAIN AND AGAIN TO ALL OF YOU!!!
