Description:

I'm receiving internal errors caused by xkbcomp not able to find newer symbols:

For example, using xvfb:

# xvfb-run -e /dev/stderr true
The XKEYBOARD keymap compiler (xkbcomp) reports:
> Internal error: Could not resolve keysym XF86FullScreen
Errors from xkbcomp are not fatal to the X server


Additional info:

* package version(s)

xorg-server-xvfb 1.20.7-1
xorg-xkbcomp 1.4.3-1
xkeyboard-config 2.29-1
xorgproto 2019.2-2


* config and/or log files etc.

* link to upstream bug report, if any

Similar to previous bug: https://bugs.archlinux.org/task/62449
Where it is suggested to recompile xkbcomp after updating xorgproto and xkeyboard-config.

Steps to reproduce:

Start any command using xvfb with stderr enabled. For example:

xvfb-run -e /dev/stderr true
This task depends upon

Recompiling xorg-xkbcomp and even xorg-server(-xvfb) doesn't fix that error here.

Yes, I was going to comment on the same!

The `xkeyboard-config` package introduced the new keysym `XF86FullScreen` in the recent `2.29` version via this merge request: https://gitlab.freedesktop.org/xkeyboard-config/xkeyboard-config/-/commit/d121a0aa5cc1de22778e2ac39929fecbe5b50623

However this symbol has not been yet added to the `libxkbcommon` package, more precisely to the file `/usr/include/xkbcommon/xkbcommon-keysyms.h`. This because the new symbol has not been added to the `xorgproto` package.

The error is temporarily fixed by reverting `xkeyboard-config` to `2.28` because this version does not have the new keysym. The proper fix should be to add the missing symbol to `xorgproto` and `libxkbcommon` and recompile everything that depends on them.

Is there something broken and not starting or is this just an error reported and as stated not fatal?

No, programs are not broken and errors are not fatal indeed. They are just annoying to see.

At the time of opening I thought it was a packaging bug but after the discovery of yesterday perhaps this task can be closed as it is actually a bug in upstream.
