Hello!
Well, I edited my lilo.conf like this
boot = /dev/hda
vga = 788
read-only
menu-scheme = Wg:kw:Wg:Wg
lba32
prompt
timeout = 80
message = /boot/message
image = /boot/vmlinuz
label = linux
root = /dev/hdc5
initrd = /boot/initrd
append = "video=vesa:ywrap,mtrr"
The two lines with vga and append are important.
Furthermore you need to run the app as root (well, so do I).
Go to the gtk homepage and follow the link to DirectFB. There are some
hints how to run a directfb-app. This should also work with plain
fb-apps.
Ciao,
Olaf
