Good day,
Thanks for the tip @Munchausen. I just installed barrier (not that I like this procedure though), and it does work on Haiku and Windows. Keymap is messed though. So need to figure out how to fix it…
Seems in my case I have to modify the config file to this: (shared with windows) Ah, and mousewheel has its own… behavior…
enable = true
server = 192.168.1.101
server_keymap = "AT"
So it seems that this is the only way to go for now if I want to use Haiku at office without hitting the power button each time I switch. Thanks for the links.
(hope the ticket gets solved though 
as I rather use physical than logical stuff for peripherals as these)
Regards,
RR
