I just installed Mandriva 2007 on my comp and at first boot everything was fine until starting kdm. Login screen went blank!
After that i tried upgrade from Mandriva 2006 but there were lot of conflicts.

So I installed MDV 2007 again but same problem.

Hardware config:

AMD Athlon TB 1300
SIS 630/730 onboard 32 MB VGA

All of the hardware was detected properly.Graphic card was detected like in Windows XP (SIS 630/730 onboard 32 MB VGA). What went wrong?
