Description Grzegorz Halat 2021-02-04 21:32:13 UTC
Description of problem:
An external display connected to laptop is not working on KDE Wayland session.

Version-Release number of selected component (if applicable):
Fedora-KDE-Live-x86_64-Rawhide-20210203.n.0.iso

How reproducible:
Always

Steps to Reproduce:
1. Boot Rawhide Fedora KDE Live ISO

Actual results:
External display is black(it is enabled in Display Configuration) and it is not usable.
It is powered-on but applications are not being rendered, the only thing which works is the mouse cursor.

Expected results:
External display should work. 

Additional info:

GPU:
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)

Laptop:
Lenovo ThinkPad P50

Disabling and re-enabling the display crashes KDE shell.
The internal display works as expected.
The same issue can be reproduced with Fedora 33.

Comment 1 Grzegorz Halat 2021-02-05 14:33:31 UTC
The same issue can be reproduced also on KDE Neon Live ISO.
Version: neon-unstable-20210131-0327.iso

Comment 2 Ben Cotton 2021-02-09 16:19:32 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 34 development cycle.
Changing version to 34.

Comment 3 Alessandro 2021-03-24 22:49:18 UTC
Same problem on Fedora.34 beta with 2 gpu (nvidia + Intel) and GNOME 40.

Nvidia screen works while Intel stays gray with only mouse working.

Using GNOME on xorg secondary screen on Intel card works fine

The problem is experienced only in Wayland

Comment 4 Alessandro 2021-03-24 22:53:51 UTC
Sorry to add this note

Mine installation is not a laptop: it is PC

Intel card is logic board integrated card

Nvidia card is addictional

I hold on kernel 5.10 due to mouse rendering bug in kernel 5.11 Kepler cards

Comment 5 Alessandro 2021-03-25 11:16:05 UTC
kernel-5.11.9-300.fc34.x86_64 fixes the issue on Gnome

Comment 6 Ben Cotton 2022-05-12 15:36:07 UTC
This message is a reminder that Fedora Linux 34 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 34 on 2022-06-07.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained.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
'version' of '34'.

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

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 34 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 Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Comment 7 Ben Cotton 2022-06-07 22:26:07 UTC
Fedora Linux 34 entered end-of-life (EOL) status on 2022-06-07.

Fedora Linux 34 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.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release.

Thank you for reporting this bug and we are sorry it could not be fixed.
