Flicker and tearing and lockup when the screensaver activates none

Description Jared Smith 2020-10-28 13:57:04 UTC
Description of problem:

I have a Jetson Nano, with Fedora 33 installed.  When I move windows in Gnome desktop, or go to the Activities corner, I see strange video artifacts (which to me, look like tearing).  As the screensaver starts to kick in, there's a tremendous amount of flickering and tearing, and then the screen goes blank.  If I move the mouse, the lock screen appears, but moving the mouse or pressing keys on the keyboard have no effect.

Version-Release number of selected component (if applicable):
20.2.1-2


How reproducible:
Very


Steps to Reproduce:
1. Install F33 Aarch64 image to a microsd card using fedora-arm-image-installer
2. Mount the SD card's boot paritition and fix the "dtb" symlink
3. Boot from the microsd card
4. Go through the initial user setup in Gnome
5. Start using the system

Actual results:
Video artifacts/tearing, and video stops working correctly after the screensaver kicks in.  System is still accessible via SSH.

Expected results:
No tearing, and no lock-up when the screensaver kicks in.

Additional info:
I'll attach some video recordings to help explain.

Flicker and tearing and lockup when the screensaver activates

This is the flickering and tearing and lockup when the screensaver activates.  Note that moving the mouse or pressing keys on the keyboard after the screen has gone blank brings up the lock screen, but the mouse cursor doesn't move and pressing keys on the keyboard doesn't bring up the password prompt on the lock screen.

Comment 3 Karol Herbst 2020-10-28 18:35:01 UTC
taking the bug. This is a known issue and is probably related with how tegradrmfb and nouveau sync on completed jobs. Thierry Redding from Nvidia has a potential fix for it, but with i915 + nouveau this also just seems to work.

Comment 4 Peter Robinson 2021-06-12 15:34:45 UTC
This should be fixed when this patch set lands upstream: https://www.spinics.net/lists/linux-tegra/msg58999.html

Comment 5 Peter Robinson 2021-07-13 19:03:57 UTC
This is fixed in 5.14.0-0.rc1.16.fc35.aarch64

Comment 6 Paul Whalen 2021-07-13 19:38:39 UTC
Verified no more tearing when testing today's nightly Workstation disk image (Fedora-Rawhide-20210713.n.0).

This message is a reminder that Fedora 33 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 33 on 2021-11-30.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
Fedora 'version' of '33'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 33 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Fedora Linux 35 entered end-of-life (EOL) status on 2022-12-13.

Fedora Linux 35 is no longer maintained, which means that it
will not receive any further security or bug fix updates. As a result we
are closing this bug.
