Comment 2 for bug 361903

I've found the solution by the Nomachine website.

The reason why this happen is the newer XServer 1.6

When you use 2 diffrent NX Systems (a older one with V 2.) on e.g. ubuntu 8.04 and a newer one V3.x - or even a V2 one on a newer XServer 1.6 (e.g. ubuntu 9.04) then this cursor keys are mapped incorrectly to the V2 NX Server.

The solution is either - if possible - update the V2 Server to a V3 Version , or if not possible add on your NX CLIENT Side the following lines into the /etc/x11/ xorg.conf file :

Section "ServerFlags"
 Option "AutoAddDevices" "false"

Note : Adding this will disable local country keyboard support, the keyboard is then set to US/English

To enable locale keyboard support again, you must write the following :

Section "InputDevice"
 Identifier "Keyboard0"
 Driver "kbd"
 Option "XkbLayout" "de"

For Example this will enable german = "de" keyboard support.

After adding this a restart of the X-Server is required.
