Bluetooth freezes keyboard
Thanks for the reply. I have actually reinstalled Linux and it is working fine. I won't try to install the Rapoo Keyboard this time. However, it was strange. None of the normal keys (letters, figures, etc) functioned, but if I pressed Strg, Alt and F1 together, that worked and I entered a command line which accepted input. I suspect that the problem lies with the Bluetooth drivers. I can usually figure out and solve problems in Windows, but I am completely new to Linux and as yet have no experience in solving problems. Thanks anyway for the offer of help.
