I just installed ATI proprietary driver: fglrx. I can now access the Gnome login screen with any version of the kernel. I however have several problems with the multi-screen management through the Catalyst Control Center. I thus cannot use this solution permanently.
However, I think that this prove that the non-proprietary ATI driver are here the source of my trouble. Does anyone knows how to fix this ? Regards.
