Hello all,

I had ubuntu 11.04 on my laptop (Samsong R525) working fine, until I upgraded to 11.10. During upgrade process everything was normal and after final reboot, I got a black screen instead of user login screen. I see grub menu but when it reach login, the screen is black.
The CPU is a kind of AMD with an ATI graphic card ( Radeon HD 6630M, ATI Mobility Radeon HD 4250)

Is there any fix for this problem?

I appreciate your comments.
Thanks,
Ali
