External Display Hard Lockup

External Display Hard Lockup

Opened this issue 2 months ago · 7 comments

Describe the bug
I have plasma6 enabled with Wayland on NixOS and have tried the following on Solus Linux as well. This issue does not occur on X11 plasma 6 or plasma 5.

The below steps causes a full hard display lockup that requires a hard reboot (press and hold power button). I've observed that the processes continue running in the background (e.g. audio from video continues playing) even while the display, mouse, and keyboard (not even caps/num lock work) are completely frozen. Sysrq commands also do not function in this state.

To Reproduce

Use wayland. This does not occur in x11.
Install kzones kwin script
Attach external display to laptop. I am using an HDMI cable.
Disable all other displays in kde using "Display Configuration"
Unplug HDMI cable from laptop.
Plug HDMI cable back in. (You may need to repeat steps 5 and 6 up to 2 times especially if this is done right after boot)
Attempt to drag an existing window or open a new window and drag it. Specifically dragging the window is what causes the hard lockup.

Expected behavior
No hard lockup

System information (please complete the following information):

KZones version: 0.9
Plasma version: Tested across the following versions 6.0.5, 6.1.5, 6.2.0
Wayland or X11: Wayland only issue

Additional context
Initially reported as a KDE bug. Ref https://bugs.kde.org/show_bug.cgi?id=494619

Answer 1 · 2024-10-19T10:40:36.000Z

I can confirm that I'm experiencing the same issue. The system locks up completely when attempting to drag a window after reattaching the HDMI cable, and a hard reboot is required to recover.

System Information:

Distro: Fedora 40
Plasma Version: 6.2.1
Graphics Platform: Wayland
KZones Version: 0.8

Answer 2 · 2024-10-19T10:58:53.000Z

Does anyone have any logs they can share?

Also, a user plugin should never be able to crash the desktop environment in my opinion, but it can, and I had to add a lot of workarounds in the past to prevent crashes like these on Wayland. But in this case I don't have any idea what could be causing this.

I don't have have a second monitor to test, so all help is welcome!

Answer 3 · 2024-10-19T15:22:53.000Z

Unfortunately, its hard to obtain logs because the system is in a completely frozen state. Where would the logs be? I may be able to see if ssh server still works during the lockup.

Answer 4 · 2024-10-19T16:35:43.000Z

Here are the journal entries from the moment the HDMI cable for the external monitor was detached and reattached, and a window was dragged, causing the DE to freeze completely.

Oct 19 17:30:32 kwin_wayland[2679]: kwin_wayland_drm: Pageflip timed out! This is a kernel bug

Answer 5 · 2024-10-20T09:42:21.000Z

In the journal, this line

kwin_wayland_drm: Pageflip timed out! This is a kernel bug

suggests it being a kernel bug, so I searched around and found this relevant bug report Window drag causes "Pageflip timed out! This is a kernel bug" , which eventually leads to kwin_wayland_drm: Pageflip timed out! This is a kernel bug.

At this point, it seems like an upstream issue to me, but the people there are still investigating, so not 100% sure

Answer 6 · 2024-12-04T16:38:57.000Z

Hi, any updates?

Answer 7 · 2024-12-23T16:56:31.000Z

Just adding that I am experiencing this as well. I am on CachyOS. I have similar logs as posted by @asmj1108 right before the freeze there are a bunch of these repeating:
Dec 23 11:34:44 siren kwin_wayland[1387]: kwin_scene_opengl: 0x502: GL_INVALID_OPERATION error generated. Dec 23 11:34:44 siren kwin_wayland[1387]: This plugin does not support setting window masks Dec 23 11:34:44 siren kwin_wayland[1387]: This plugin does not support setting window masks Dec 23 11:34:44 siren kwin_wayland[1387]: This plugin does not support setting window masks

More info:

I am not on a laptop, but I do have 2 displays connected.
one of my displays is not always on and enabled in kde display settings. but either way, this will seem to occur, I will try to track more closely now that i know it is this script.
The lock up seems to always occur when I go to grab a window with the mouse. The pointer freezes and whole system freezes, and I have to hard reboot.

Hopefully this can get fixed! This is an absolutely excellent script and precisely what i was looking from after moving to Gnome from KDE. I used the TilingShell extension, and this one you've made is super close to that. Assuming this issue gets fixed, I have a few feature requests I can drop here, and also happy to support (as I did TilingShell!)
Thank you!
