FBSplash for Gentoo

For the logs and Google (I use FBSplash for quite a while already):

(Inofficial) Gentoo FBSplash Howto
(Inofficial) Gentoo FBSplash in 5 steps Howto

Upgrading a FBSplash kernel once you’ve already installed one (procedure for a laptop/desktop or workstation -> you don’t want to use fbsplash on a server, do you?):

1. # emerge -u gentoo-dev-sources

2. # cd /usr/src/linux-{your new gentoo-dev-sources}

3. # make mrproper (just to make sure everything is clean)

4. # cp ../linux-{your previous gentoo-dev-sources}/.config .

5. # make oldconfig

6. verify the new kernel config (if required): # make menuconfig

7. # mount /boot

8. # make && make install modules_install

9. adjust /boot/grub/grub.conf to boot the new kernel. keep the old section as a fallback. a valid section for my box (with a 1400x1050 screen) would look like (don't copy this as it probably won't work for you. just take it as an example. note that the "kernel /boot/vmlinuz .. theme:emergence" line is very long.):

default 0
timeout 5

title=Gentoo Linux 2.6.8-r4 (new fbsplash)
root (hd0,1)
kernel /boot/vmlinuz root=/dev/hda4 video=vesafb-tng:ywrap,pmipal,1400x1050-32@60 splash=silent,theme:emergence
initrd /boot/fbsplash-emergence-1400x1050

10. adjust the /usr/src/linux link:
# rm /usr/src/linux
# ln -s /usr/src/linux-{your new gentoo-dev-sources} /usr/src/linux

11. # reboot

12. after rebooting, make sure that the correct kernel has been booted (see # uname -a)

13. remerge any kernel-dependent ebuilds.
if you use the binary x11 driver by nvidia, do:
# emerge nvidia-kernel
if you use the ndiswrapper (wlan; intel pro wireless bg 2100/2200 etc.):
# emerge ndiswrapper
if you use alsa you might need to remerge alsa-utils:
# emerge alsa-utils

14. if anything had to be emerged in step 13, do
# reboot

15. if everything works fine, you might want to remove the following things:
- previous kernel sources (# rm -rf /usr/src/linux-{your previous gentoo-dev-sources}/)
- previous kernel modules
# rm -rf /lib/modules/{your previous gentoo-dev-sources kernel modules}
- previous kernel in /boot:
# mount /boot
# cd /boot
# rm vmlinuz.old
# rm vmlinuz-{your previous gentoo-dev-sources kernel}
# rm config.old
# rm config-{your previous gentoo-dev-sources kernel}
- adjust /boot/grub/grub.conf accordingly (remove the section of the previous kernel)

have fun :)
