Could you try below command to see if it fixes your issue

thidau,

Here is the test kernel which should fix this issue, could you give it a try?
https://people.canonical.com/~acelan/bugs/lp1875254/

BTW, the kernel version is the same as yours, so you have to remove the installed image before installing the test kernel.
sudo dpkg -r --force-all linux-image-5.4.0-26-generic

Okay, I built another older version of the kernel for testing.
https://people.canonical.com/~acelan/bugs/lp1875254/
BTW, 5.4.0-28 is just released today, maybe you could install that new kernel and then try the test kernel to make sure you have a working kernel installed.

The test kernel on my XPS 13(2020) fixed the same issue as you described and doesn't introduce any regression. The patch applied on top of 5.4.0-21/5.4.0-26 is below commit which also could be found in the directory with the test kernel.

Subject: [PATCH] drm/i915: Limit audio CDCLK>=2*BCLK constraint back to GLK
only

Revert changes done in commit f6ec9483091f ("drm/i915: extend audio
CDCLK>=2*BCLK constraint to more platforms"). Audio drivers
communicate with i915 over HDA bus multiple times during system
boot-up and each of these transactions result in matching
get_power/put_power calls to i915, and depending on the platform,
a modeset change causing visible flicker.

GLK is the only platform with minimum CDCLK significantly lower
than BCLK, and thus for GLK setting a higher CDCLK is mandatory.

For other platforms, minimum CDCLK is close but below 2*BCLK
(e.g. on ICL, CDCLK=176.4kHz with BCLK=96kHz). Spec-wise the constraint
should be set, but in practise no communication errors have been
reported and the downside if set is the flicker observed at boot-time.

Revert to old behaviour until better mechanism to manage
probe-time clocks is available.

The full CDCLK>=2*BCLK constraint is still enforced at pipe
enable time in intel_crtc_compute_min_cdclk().

The main status for this bug is 'Invalid' which doesn't sound right. Can someone fix that up?

That's a series holder, we're going to fix this issue on focal, so focal status as "in progress".
If "linux (Ubuntu)" is not invalid, it kind of affects the script to determinate if we solved this issue on all series.

Note that we're required to ensure fixes are in groovy before focal, so it really should be tracking groovy and not 'Invalid'.

Hi Acelan Kao
I've give a try to your test kernel and I confirm it resolve the display blackout. Great !
Unfortunately I've found a bug while I close the session. Just closing the session freeze the desktop during at leat 2 minutes; when I shutdown it take also a long time with just black screen and underscore before closing.
Hope that's help

Hi AceLan
Just another data point on Dell XPS 9300. I had the exact same problem and your test kernel fixed it.

Thanks

Daniel,

This commit is backported from v5.6-rc1, so groovy is not affected.
It'd help to clarify other flicker issues with "ice-lake-flicker" if those bug reporters could try this test kernel.

Thidau,

It looks like you encountered other issues, please file another bug report if you could reproduce it regularly.

Hossein,

Glad to hear it works for you.

Hi,

I am strugling with the issue of flickering as well on ubuntu 20.04.
When login it keeps flickering the screen.

I've tried both version of the kernel mentioned before:

`https://people.canonical.com/~acelan/bugs/lp1875254/`

unfortunatelly issue persist.

Only fix working for me is mentioned before:

```echo on | sudo tee /sys/bus/pci/devices/0000:00:1f.3/power/control```

but it doesnt solve it always on the first time so sometimes I have to keep running it for until it kick in.

I am using using laptop Dell xps 15.

Could you let me know if there will be any patch released for that or if I can try some other method.

P.S. I was trying as well this:
https://kernel.ubuntu.com/~kernel-ppa/mainline/drm-tip/current/

but didnt succeed with applying patches (i was getting some errors that I could not resolve)

Just to give you an update from my case.
- Updated Kernel for latest - didnt work
- Ubuntu to 20.10 (daily build) issue keep persist

Decided to go hard way - backed up all my data and installe fresh 20.10
All works fine

I am thinking the problem could be that I had installed workspaces-grid on 20.04 and that was causing the issue. Didnt show from the beginning only when did one of the updates on 20.04 so I thought one of those updates broke it but moving to 20.10 and having same issue made it clear was not any of the updates. This is only my suspissions reg workspaces-grid - I am not installing it anymore tho.
