What's wrong with this case? Virtual machine reports invalid key codes to the guest? You need to have the proper layout in Windows, as (virtual) hardware only reports key codes.
A few months have passed and I might not remember everything correctly, but there was a series of problems:
- I use several symbols as Greek letters (α, β, γ…) and mathematical operators (×, −, ·, ∂…), and after much digging I found that the only way I could make keyd work with them was to choose a US keyboard layout. So, I had to write a configuration file for keyd to remap not only the special characters listed above, but every character of the Italian keyboard (è, é, ò, à, ù…). This extensive remapping required then an exception for Espanso to prevent `keyd` from intercepting its virtual keyboard output.
- However, this forced US-layout setup created a conflict with VirtualBox that I was unable to solve. When I installed Windows and selected the Italian layout inside the VM, the guest OS received the raw key codes corresponding to a US physical keyboard (due to the keyd remapping layer). Since the guest OS expected Italian key codes, all the standard Italian keys (like è, à, ò) stopped working correctly. Without keyd enabled, the standard Italian layout worked perfectly in the VM.
- The attempts to create application-specific exceptions (e.g., to disable keyd for the VM window) using tools like keyd-application-mapper did not function correctly in my KDE environment because of known issues in these tools.
- Finally, introducing new hardware like my Corsair keyboard added another layer of complexity, as its Linux driver (ckb-next) was incompatible with the active keyd remapping layer. This was the point when I decided to revert to X11.
I should definitely collect all these details and write a blog post about it…
