the bug disappears when starting the system with boot option nomodeset
The problem was caused by the kernel module mgag200 which was loaded automatically (by KMS?) and this prevented the mga driver to work (see
bugzilla.novell.com/show_bug.cgi?id=834992
).

I understood the problem. This is Java bug with some linux GUI. I do not know how to fix it in linux. In opensuse starting the system with boot option 'nomodeset' can fix it.
The root of evil in hiding of cursor pointer above mainboard and welcome-touch-module.
If to fix it is unsolved problem for you then I will give you QSystem.jar for replacing with key '-no-hide-cursor'.
Any way this key will be include in next version with italian translation.
