Alt remaps do not work on GTK apps on GNOME under Wayland.

[denysonique]

When using the simple below example config Xremap does not perform the select all action on Gedit.
In the same GNOME session it works for Kate under XWayland.
For KDE Wayland it also works with no problem.

keymap:
  - name: Emacs bindings
    remap:
      M-a: C-a

gnome-shell: 42.5
Kernel: 5.19.0-41-generic #42~22.04.1-Ubuntu

I suspect you might be using the x11 binary instead of gnome one. You're supposed to use the gnome xremap if you use GNOME under Wayland.

If you're not using it yet, please install https://extensions.gnome.org/extension/5060/xremap/ first, and then install the gnome xremap.

I am using v0.8.5 from xremap-linux-x86_64-gnome.zip

$ md5sum xremap
2b3485585081e20c2d348ac2fe4a8ce9  xremap

I do also have the extension installed

$ gnome-extensions list --enabled | grep xremap
xremap@k0kubun.com

I also tried the cargo install xremap --features gnome version to no avail

After inspecting what events get sent etc I realized a delay may be helpful and It appears that keypress_delay_ms: 20 seems to help.

Oh, I see. Thank you for finding a workaround. We've seen a similar report before, but the event sequence generated by xremap was correct and the same thing just worked for X11. So I currently blame Wayland for not handling delay-less sequences properly.

We should probably build an evdev-only repro of this issue and report it upstream, but in the meantime, please consider using the keypress_delay_ms workaround.
