Hi dear,
I have a Omen core i7 running manjaro linux with plasma 5.26.5, with a hybrid GPU, Intel UHD 630(mesa video drivers) and Nvidia GeForce 1650 mobile. When I activate a dual screen with any kernel (5.10, 5.15, 5.19, etc.) the primary screen flickering a lot, after several tests the system only work with the kernel 4.19, any idea why? i can´t upgrade the kernel because the flikering issue comes up, if anyone can help me to fix this issue i will appreciatte a lot,
regards…

Hello,

Try to boot those kernels using ibt=off kernel boot parameter and see if the issue persists.

Hi, Thanks a lot for your response.
I added the ibt=off line to the grub bootloader with no luck, the issue persist, any other idea?

try adding this parameter:
sudo nano /etc/default/grub
and inside this line: GRUB_CMDLINE_LINUX_DEFAULT inside the quotes add this parameter:
i915.enable_psr=0
dont remove anything, just add it to existing parameters, save the file with ctrl+x, press ‘Y’, then enter and update grub:
sudo update-grub
reboot and test
