Hi,
Our client is not able to use her Numeric Keypad.
The only option is to switch NumPad Off, which switches in On.
Ie NumLock key works in opposite way.
I tried the same with my X2Glient, and NumLock works as it should.
Server: Ubuntu 4.5.0-1042-azure
Deskop: Mate
Client: v. 4.1.2.1
Client keyboard: HP KU-1156
The only difference seems to be the keyboard model.
