Sorry, if this is a FAQ, but I couldn't find with a quick look.
My debian testing has X 4.1.0.1 and fades white switching from console back to X. SuSE uses 4.0.3 and is o.k. Only difference I found was : in Suse.xfree.log: (II) Open APM successful (II) Module ABI versions: XFree86 ANSI C Emulation: 0.1 XFree86 Video Driver: 0.3 XFree86 XInput driver : 0.1 XFree86 Server Extension : 0.1 XFree86 Font Renderer : 0.2 which doesn't appear in /var/log/kdm.log as well as the line ABI class: XFree86 Video Driver, version 0.3 appearing in the SusE log not in debian .. any help appreciated. thanks, tobias.
