Bug Description

Laptop internal display shows random looking 'static' after it's turned off and then on again. e.g. on suspend/resume, or when plugging/unplugging an external monitor.

This appeared to come after a `dist-upgrade` took the kernel from 5.11.0-44 to 5.13.0-25 (hwe).

Others are seeing this with both NVidia and AMD graphics hardware:
- https://www.reddit.com/r/Ubuntu/comments/s8c83w/laptop_shows_static_screen_after_going_into_lock/
- https://www.reddit.com/r/Ubuntu/comments/s8fit0/please_help_static_noise_display_on_ubuntu_2004/

I use i3 under gnome-flashback, but tried using default Ubuntu/Gnome both X and Wayland, and gnome-flashback/metacity. All showed the same problem.

Also tried an `apt install --reinstall xserver-xorg-video-radeon libdrm-radeon1` for luck - no joy.

Running a 20.04.3 live stick the problem does *not* occur.

The duplication of this to https://bugs.launchpad.net/bugs/1958412 is not appropriate I think.

* I do not have the symptoms described in the other bug
* The workaround described there (remove `quiet` from grub command line, plus `update-grub` of course) does not help, unsuprisingly.

Also the `[amdcpu]` addition to the title seems inappropriate since people seem to have the same issue on NVidia.

To be clear: the other issue is random display noise during boot and shutdown. I do not see that. The other bug does not mention this bug's symptom, which is an unusable display if it's ever turned off and then on again (e.g. by suspend/resume, or external monitor plug/unplug).

To be clear - the display shows static and never returns. This is not a transient issue. The display is only usable from first boot until it is first turned off, after which it only displays static.

So this is a serious bug, especially if you don't have an external monitor, your only option is a hard reset.

Good morning,

Chiming in to say that I am experiencing the issue exactly as described.

Going into lock screen or leaving the device idle (no mouse or keyboard input for about 1 minute) is enough to trigger this unique display error.

Here is a link to an unlisted YouTube video, 35 seconds long, showing the buggy display:

as OP jamesf said, the internal display can only be recovered by a hard reboot.

Happy to help test solutions, thank you

+1, I have the same issue as here, and not #1958412 (grub workaround described there doesn't fix the issue). Though maybe it is marked as duplicate if the underlying issue is the same in both cases...

James Ferguson (jamesf) wrote :

Trouble with the duplicate status is the other issue has mostly cosmetic consequences and a workaround, while this has neither of those things and it could get lost that this is a critical problem.

It does seem like more than coincidence that the new kernel has brought two (or more) screen-noise problems. I wouldn't be surprised if there is a common underlying issue.

This is almost certainly bug 1958412, which was the first to report the static noise regression on the amdgpu driver after kernel 5.13 was introduced to Ubuntu 20.04.

Also ignore all comments that mention Nvidia because GNOME and Ubuntu only uses the primary GPU for shell rendering. Never the secondary GPU.

Having just this bug separate when all the other reports of it are pointing to bug 1958412 probably won't help you.

James Ferguson (jamesf) wrote :

There may be better ways to downgrade the kernel(?), but what I've done is re-install the previous 5.11 kernel:

  sudo apt install linux-image-5.11.0-46-generic linux-headers-5.11.0-46-generic linux-modules-extra-5.11.0-46-generic

Then edit /etc/default/grub to change the GRUB_DEFAULT line to select this kernel by default:

  GRUB_DEFAULT="Advanced options for Ubuntu>Ubuntu, with Linux 5.11.0-46-generic"

and then run `sudo update-grub` and reboot. Now `uname -r` shows 5.11.0-46-generic.

This will lock you on that kernel forever (no security patches!). You should watch these launchpad bugs for changes to know when to undo it. Undo the change by returning /etc/default/grub to having `GRUB_DEFAULT=0` and re-running `sudo update-grub`. Once everything is back to normal you can then `apt purge` the packages above installed with `apt install`.

Thanks, booting into a different kernel version worked. I installed 5.11.0-46 like you said, but then when I went into advanced options in my boot menu there were three versions listed, so maybe I didn't have to do that. I also didn't bother changing my grub default. I'll just choose my kernel manually every time I restart, and when it's time to go back to normal I just have to stop doing that. Thank you for the advice!

Bugs mentioning or showing "Static" pattern of display at either boot or suspend, mostly on Renoir 1636

"Blinking / Flickering, rather than static reported, devices other than 1636:

#1958523: ???? [AMD/ATI] Stoney [Radeon R2/R3/R4/R5 Graphics] [1002:98e4]

#1958890: Ideapad 3 "Blinking/Flickering"; [AMD/ATI] Device [1002:164c] (rev c1)

While it has to be a strong probability it's all one issue, there is a bit of a split between static on 1636 devices and blinking/flickering on others. Note the non-1636 bug in the "static" list seems slightly different and the static occurs from different triggers, but then that's hardly surprising with a different device even if it's one issue.

I reported #1959340, and to clarify, what I see _could_ be characterized as flickering. I called it "snow" in my report to compare it to the reception from a TV with a terrestrial antenna. Each pixel on the screen seems to get constantly changing rgb values.

One thing I've noticed is that the right side of my 16:9 gets _lines_ with constantly changing rgb values.

I can catch it on video if that's helpful.

@akkartik - I assume yours was the same as my https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.13/+bug/1958591/+attachment/5555993/+files/PXL_20220119_165211771.jpg, since we have I think identical machines.

Personally I'd have assumed anything described as "flickering" to be different, since the underlying screen image is not even visible. But it could be that some of the bugs I listed separately actually saw this "static" / "colored snow" display. I think not everyone sees the vertical bars on the right that we do.

I made a experiment and I can confirm static noise after waking from suspend.

@jamesf My device model is Lenovo Ideapad 320. You can update your post.

I will copy my other post since we are tracking this bug here: When your computer boots press escape (UEFI boot) or shift (BIOS boot). You may have to try several times to press it in right time. A menu should appear. Choose option 'Advanced options for Ubuntu'. Then choose 'Ubuntu, with Linux 5.11.0-46-generic'.

Then you can follow instructions in post #15 to boot with Linux 5.11.0 by default.

James, it is common for people reporting bugs to choose their words somewhat inaccurately. "Flicker" is often used by people to describe graphical bugs that are not flicker.

I have an external monitor plugged in all the time, that means after the display manager starts, the internal monitor is unusable (showing "snow" and lines).

fixed this temporarily by booting 5.11 kernel instead of 5.13

I also have this issue on a Thinkpad T14s, AMD Ryzen 7 PRO 4750U.

The issue is not present with kernels 5.9.10 or 5.15.23. It is present with the default kernel from the most recent KDE Neon (5.13).

Here's a short video, it's the same pattern (static and vertical lines on the right) as the other video in this thread:
https://twitter.com/tlhunter/status/1493107390731874305

The pattern is reminiscent to an HDMI desync issue but the vertical lines do make it distinct.

It appeared to affect the laptop screen but not an external display. The static appeared after the screen went to sleep and woke back up, though I don't believe the system went to sleep.

The issue appears with the kernel linux-image-5.13.0-1022-oem when is waked up from sleep.
The issue is not present with older kernel version. Downgrading to an older version solves the problem.
The laptop becomes useless without an external display.

Excellent - also confirming - current kernel that came through in normal updates fixes the issue. Thank you devs.

    $ uname -r
    5.13.0-30-generic

I posted one option for fixing the machine on 5.11 kernel in comment #15. To undo that:

0. update your packages
1. Restore /etc/grub/default to have the line `GRUB_DEFAULT=0`, then run `sudo update-grub`.
3. Reboot and then confirm the with `uname -r` that you are on 5.13.0-30-generic and the issue is fixed.
4. If all is well, to remove the 5.11 packages so they're not on your system forever: `sudo apt purge --autoremove linux-image-5.11.0-46-generic linux-headers-5.11.0-46-generic linux-modules-extra-5.11.0-46-generic`.

Changed in linux-hwe-5.13 (Ubuntu):
status: Confirmed → Fix Released
tags: removed: rls-ff-incoming

That didn't fix the bug in my case. Should I create new bug report?

I am seeing this static since kernel 5.13.0-28 and even now after today's update to kernel 5.13.0-35 the static still appears for a while while rebooting / shutdown.

The issue is same, "Laptop internal display shows random looking 'static' after it's turned off"

This is ASUS Laptop with AMD Ryzen 7 3750H with Radeon Vega Mobile Gfx
