Raw keymapping of AltGr on Windows Host not working #43

Open Kjubyte opened 1 year ago

Kjubyte commented 1 year ago

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?

csarn commented 3 weeks ago

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.
