Thx , it works ....
the tread "RH9...Kernel...Nvidia..." was very helpfull....
for all who get the same problem:
download the src.rpm from kernel...
rpm -ivh k_athlon-2.4.20-100.src.rpm
it works !!!!
Well i guess i downgraded the kernel because after i runned yast online update it patched my kernel, but the was not a problem after i installed the nvidie driver
after i patched, than the kernel and Nvidia driver it still works
Thx all for help !!!
