[Solved] Issue : qemu virtio/keyboard libinput sway/wayvnc

Hi !

I'm making an Arch Linux VM with qemu/kvm with virt-manager running headless sway through waynvc.

I configured the ps2 input keyboard :

input '0:0:wlr_virtual_keyboard_v1' {
    xkb_layout "fr"
    xkb_model "pc105"
}

But my first issue was that AltGr is mapped to ISO_Level3_shift keycode.

I tried to add a virtio keyboard with virt-manager. It's listed with libinput (as root) but not when I try to access it with swaymsg IPC (as my user)...

Thanks for the help !

[EDIT] : I've found the solution for my AltGr key.
The issue was wayvn keyboard layout config which is needed (in addition to sway-input config).
And the ISO_Level3_Shift is correct.

Below my systemd/user services units :

/etc/systemd/user/sway_homed.service :

[Unit]
Description=Headless Sway service for %u

[Service]
Type=simple
Environment=WLR_BACKENDS=headless
Environment=WLR_RENDERER=pixman
Environment=WLR_LIBINPUT_NO_DEVICES=1
Environment=XKB_DEFAULT_LAYOUT=fr
ExecStart=/usr/bin/sway
Slice=session.slice

[Install]
WantedBy=default.target

/etc/systemd/user/wayvnc_homed.service :

[Unit]
Description=Remote desktop service (wayvnc) for %u
After=sway_homed.service
BindsTo=sway_homed.service

[Service]
Type=simple
Environment=WAYLAND_DISPLAY=wayland-1
ExecStart=/usr/bin/wayvnc --keyboard=fr

[Install]
