[Linux-fbdev-users] rivafb results in black screen

[Sebastian M. <ins...@gm...>]

Hello,

I have a Geforce Ti4200 with a LCD attached to the DVI-Connector. My
computer is running Debian with kernel 2.6.10. I compiled the =
rivafb-driver
into the kernel. But when I boot, I see only a black screen.

debian:~# dmesg | grep rivafb
