Assertion `wlserver.wlr.virtual_keyboard_device != nullptr' failed.

I experienced the following error when starting gamescope:

gamescope: ../src/wlserver.cpp:984: void wlserver_key(uint32_t, bool, uint32_t): Assertion `wlserver.wlr.virtual_keyboard_device != nullptr' failed.

The problem is that a key event is received by the SDL window before wlserver_init assigned virtual_keyboard_device. The event received by SDL is always SDL_KEY_DOWN with key == 42.

The event seems not to be triggered by the user but coming from somewhere else. It was reproducible 100% until I played a bit with the gamescope source, upon which it completely stopped from occurring.

Environment: Linux 6.0.3, sway 1.7, Intel(R) Xe Graphics (TGL GT2), gamescope HEAD (2f95c0f)

I was having this issue as well. Were you by chance on xwayland-22.1.4? I have updated to xwayland-22.1.5 and I have not yet had the issue again.

[t-8ch]

Yes I was on 22.1.4. But it was also on 22.1.4 when it went away again.

This was what I was getting:

The command being run was gamescope -W 1920 -H 1080 -f -- /usr/bin/grapejuice player %u

As I said I'm no longer receiving this error.

[t-8ch]

For me it was the same except for running vkcube on Intel(R) Xe Graphics (TGL GT2)

I get this error intermittently. I am on an up to date arch install with mesa/lib32-mesa 23.0.0-rc4 installed along with gamescope-git. I normally use steam-native. Once the error starts happening it happens with plain steam too. gamescope is setup for specific games. So far rebooting fixes it for a few days. Here is a sample log (-condebug):

When it works (after a reboot) this is what follows the 'Fossilize' message:

If anyone else is having this problem on KDE Wayland, I just found out that System Settings > Applications > Legacy X11 App Support > Allow legacy X11 apps to read keystrokes typed in all apps causes the crash if it's set to something besides "Never"

[awsms]

having this on both KDE (X) and Cinnamon

[melvyn2]

Setting the KDE X11 keystroke setting did not fix the crash for me.

[Jimbleton115]

Changing the KDE X11 keystroke thing didn't fix it for me either

[Florennum]

same issue here, plasma wayland with the same specs(almost). downgrading might work? i need to test

[FlpCastilho]

Been having the same error since moving to Plasma some months back, changing the KDE X11 setting has not fixed the issue, unfortunately.

[MarcEichler]

I have the same problem running 3.12.5 on NixOS. Setting X11 keystrokes to "never" does not fix it for me either.

[walseb]

I'm getting this issue on NixOS in a plain (no plasma) xorg session. This is the error I'm getting:

wlserver: [backend/headless/backend.c:68] Creating headless backend
gamescope: ../src/wlserver.cpp:1414: void wlserver_key(uint32_t, bool, uint32_t): Assertion `wlserver.wlr.virtual_keyboard_device != nullptr' failed.

[sharkautarch]

@t-8ch @walseb @MarcEichler @kisak-valve I believe this issue should be fixed by commit https://github.com/ValveSoftware/gamescope/commit/be20af6e4f605dc159265a71b85d898643528c5e in upstream gamescope
