If your Numpad keys suddenly move your Cursor instead of writing numbers, try this:

System -> Settings -> Keyboard -> Mouse keys (4th tab) -> deselect "Allow to control the pointer using the keyboard".

Getting GtkRadiant to run under Ubuntu isn't that easy. First you try to follow the Compiling Howto and in the end you'll recognize that "scons SETUP=0" doesnt work.

Why doesn't it? Cause there are packages missing!
Besides the packages mentioned in the Compiling Howto, following packages are needed too:

• g++
• gcc
• libgl1-mesa-dev
• libglib2.0-dev
• libgtk2.0-dev
• libgtkglext1-dev
• libxml2-dev

And thats it! (If I missed any, please let me know.)

Now you can go on with "install:". ;)

Wenn dein Numpad plötzlich den Cursor bewegt, probier das:

System -> Einstellungen -> Tastatur -> Maustasten -> "Allow to control the pointer using the keyboard" ausschalten.

Ich habe mich sehr lange (15 Minuten) mit diesem Problem auseinander gesetzt und habe dann - Google sei Dank - das hier gefunden:
