Warning: Unsupported high keycode 372 for name <I372> ignored

[GuillaumeSeren]

Hello,
since a few weeks I have been getting this new error:

Warning:          Unsupported high keycode 372 for name <I372> ignored
                  X11 cannot support keycodes above 255.
                  This warning only shows for the first high keycode.

Maybe it come from my setup, but since it is new I think it might affect others too.

Maybe link to the bug https://gitlab.freedesktop.org/xorg/xserver/issues/260 (originally open in 2007 at https://bugs.freedesktop.org/show_bug.cgi?id=11227). They say:

wayland uses 32 bit keycodes, so it doesn't have the same limitation.

Therefore maybe try with Wayland.

I havn't installed Lafayette, because I want use it in computers without root privileges. Therefore I launched it with command xkbcomp -w9 /opt/lafayette_linux_v0.6.xkb $DISPLAY) and I have a lot of warnings like that

For Lafayette Version : https://github.com/fabi1cazenave/qwerty-lafayette/blob/master/releases/lafayette_linux_v0.6.xkb
I have

Warning:          Unsupported high keycode 372 for name <I372> ignored
                  X11 cannot support keycodes above 255.
                  This warning only shows for the first high keycode.

@fabi1cazenave you said me, If I recall, that this sort of warnings was not printed under Ubuntu 12.04, but is printed in current version of Ubuntu. I havn't noticed any limitation, it's just a warning, maybe not important.

Hey @JulioJu
thank you for the quick reply.

I havn't installed Lafayette, because I want use it in computers without root privileges. Therefore I launched it with command xkbcomp -w9 /opt/lafayette_linux_v0.6.xkb $DISPLAY) and I have a lot of warnings like that

I use lafayette wihtout root 😈
I keep the source somewhere and then load it in my xsession with xkalamine --apply~/src/lafayette/layout/querty.yaml.

The layout still works great and I think it is just a warning,
so let's close this.
