Hi,
I installed the system on a new desktop computer but now can't enter it, as it requires password entry at the point when my Bluetooth keyboard is not yet hooked up. Ended up ordering a USB keyboard anyway, but I thought I should report this issue here.
AN UPDATE: I bought a USB keyboard and used it to enter the installed OS for the first time. After that, I set up the Bluetooth keyboard again (the first time was during installation), and now it is initialized without a problem in the login dialogue. This means the problem only exists when OS is run for the first time.
In my view, adding a virtual keyboard option in the login dialogue could be a solution.
