Hi alltogether! On my new Powerbook G4 12" I couldn't use the nVidia framebuffer-console with kernel 2.4.23-ben1. I only saw vertical white stripes between booting and the start of gdm or a patchwork image of the X-screen when switching to tty1. The problem was the unknown PCI-ID of the graphics card. With the attached patch the problem is solved: I can use the framebuffer-console.
Together with the patch from Guido G�nther at http://honk.physik.uni-konstanz.de/~agx/linux-ppc/kernel/rivafb-blank.diff I can use fblevel to switch the backlight on/off. The patch and the one I sent before (for the detection of my PowerBook) were derived from Guido G�nther's patches at http://honk.physik.uni-konstanz.de/~agx/linux-ppc With the patch I am also able to choose between video=riva and video=ofonly at boottime if both are compiled into the kernel. Without boot parameter rivafb is chosen. Best regards, Wolfi PS: cat /proc/fb tells me 0 GeForce-FX-Go-5200 or 0 OFfb /[EMAIL PROTECTED]/NVDA,[EMAIL PROTECTED]/NVDA,D
