KVM: Vial on Linux (AppImage) not detecting Keyboard via KVM

[SHU-red]

Similar to #237 but placed on Linux

If i connect my 3w6 keyboard via my KVM extension it does not get detected
If i directly attach it to my PC (which is placed on another level), it gets detected

Would be very handy if i would not have to move my keyboard around for configuration

Vial 0.7.1

Python 3.6.15
Qt 5.9.3
