Possible Workaround for intel UHD 6xx graphics: Switch to Wayland from
X11
When I compared package listings between my screen tearing / glitching

install I noticed that the latter had additional wayland packages.
This gave me
I still experience screen tearing / glitching after upgrading my
computer with intel UHD 630 graphics from Kubuntu 22.04 to 24.04.
However, if I perform a fresh install of Kubuntu 24.04 (in a separate
partition) there are no screen display issues.
I wonder what the difference is?
Ideally I would
I'm using 24.04 LTS.
Upgrade to 6.11.0-17-generic did not resolve the flickering screen.
It still occurs when my mouse cursor is in the lower part of the screen.

This bug was originally reported for older Intel HD 5xx graphics and was
fixed some time ago in both 6.8 and 6.11 branches.
Judging by the reports above, some owners of Intel UHD 6xx are still
reporting issues. I am not sure if the issue they are having is related
but If your machi
Hi!
I am using Ubuntu 22.04.5 LTS now.
If I upgrade to 24.04.2 LTS (6.11 kernel version) will it work without a
workaround?

I also experience flickering/glitches with my Intel i7-10700k.

I would like to assist.
However, if you really want me to test the new kernel, I need more detailed
instruction.
I gave it a try, but my update manager crashed several times.
As yet, I leave testing the new kernel to the Ubuntu experts.

Thank you Douglas Gilbert, I welcome the news that there is a fix in
kernel 6.11. Still, I prefer using a LTS release. I am eagerly waiting
until Ubuntu 24.04 LTS will get a kernel that solves this annoying long
term bug.

My suggestion is to try 24.10 and use kernel 6.11. That fixed all my
problems with flicker.

I'm experiencing severe flickering when the mouse cursor is in the
bottom quarter of the screen. It stops when I move the cursor.
The proposed workarounds do not work for me.
I tried all suggested alterations to grub line GRUB_CMDLINE_LINUX_DEFAULT.
No luck.

I tried to use both kernels in my Latitude 5440:
linux-image-6.8.0-51-generic
linux-image-6.11.0-1010-oem
Both have the flickering problem.
The option intel_iommu=igfx_off make the flickering less often but do not solve
the problem.
intel_idle.max_cstate=2 i915.enable_dc=0 make it worse.

@burger.ga — This looks like a different problem, as far as I can tell.
I suggest asking on Ubuntu Discourse for some help to diagnose and fix
this.

I certainly does not look like my case, where it happens during x
session and the whole screen truns off for some time (like several
seconds) and then turns on.

Disabling PSR2 doesn't do anything for me... Also testing 6.11 doesn't
do anything to solve the issue. I'm starting to think I may have a
separate issue.
Could someone check https://photos.app.goo.gl/at33cQcpw6wrvAqW7 to see
if this is a separate problem? Somewhere in the boot process the screen

First, since linux 6.8.0-48 I consider the bug to be fixed at least on
the hardware it was reported on.
Second, I see bots adding requests for testing obscure kernel versions

to react to this. Can some one with auth
