Hi, first of all: Awesome work! Thank you. I'm using waynergy for a few months now but there are two things that I couldn't get to work. One thing is the mapping of the AltGr key from ISO keyboards from a Windows host to Linux KDE using raw keymaps.

When I press AltGr (ISO_Level3_Shift) Windows is sending two different button presses: Left CTRL (0x1d) and Right Alt (0x0138), but there are some differences in the mask. See Debug Log from Barrier.

On Linux they are translated to CTRL + Alt and not AltGr.

Barrier Log Left CTRL:

This is one of the the weaknesses of the KDE protocol at the moment. Within waynergy there's not much that could realistically be done, as unlike wlroots there's no control over the higher level layout to treat this combination appropriately. Does KDE have the ability to set xkb options for the virtual input device?

Any news here? Did the KDE protocol improve since this ticket was opened? I'm experiencing the same problem, with waynergy 0.0.17 on Plasma 6. On a german layout, there's just too many important symbols reachable via ISO_Level3_Shift to accept that key not working.

Being still annoyed by this bug/missing feature, I started wev to look at what keystrokes are actually received on AltGr.
It is a combination of both Control_L and ISO_Level3_Shift.
So I tried a workaround: Press the actual left control key, then AltGr, then release the control key.
This works! It is still annoying, but way easier than copy/pasting the necessary characters from somewhere.
