I have Intel(R) UHD Graphics (CML GT2) and using i915 driver.
Added below lines to grub:
i915.enable_dc=0 intel_idle.max_cstate=2
No luck.
Then changed it to:
i915.enable_dc=0 intel_idle.max_cstate=4
as per some suggestions
Also no luck.
I experienced the issue a few years back. Can't remember the Ubuntu version then. After adding above lines it was OK. Then after a kernel update it was all fine even without adding the above lines.
Now, after upgrading to 24.04 the problem came back.
It happens randomly for a coupe of seconds every an hour or so.
It affects me as well.
