| 1. | How can I disable framebuffer in the kernel without recompiling the
kernel ?
|
| You would boot using the following boot parameter:
vga=normal
The kernel will then boot in text mode instead of the frame buffer.
Simply put the above into the "append="
line in /etc/lilo.conf and rerun
lilo.

| 2. | How do I turn on the graphics in the background of the boot messages ?

-
First, you need the following packages installed:
-
Second, make sure the following is enabled in /usr/src/linux/.config
CONFIG_FBCON_SPLASHSCREEN=y
It's located under the kernel config section
Console drivers
|
+->Frame-buffer support
|
+->[*] Use splash screen instead of boot logo
If it's not selected, you'll need to recompile the kernel to enable splash
screen support.
-
Finally, you'll need to enable the splash screen with mk_initrd and lilo
(where -s represents the desired resolution):
mk_initrd -k "vmlinuz vmlinuz.suse" -i "initrd initrd.suse" -s 1024x768
-
add the following line to your
/etc/lilo.conf
vga=791
-
Then, reboot and enjoy the purty pictures.
