Hi,
I am trying to install Gentoo and as I am far from being an expert, I humbly start with
Code:
genkernel all
.
All seems to be well and I can manage to start my new gentoo
Where things turn out to be more difficult is when I intend to install the X server. I am told to make complements to the kernel config I got without any merit at all, with genkernel.
I say to myself go to /usr/src/linux et launch a
Code:
genkernel --menuconfig all
, so we will restart from our previous conf and take into account modification.
Things seem to be different as my kernel compile crashes.
My question is how to restart from the config a genkernel all has let in order to improve it step by step ?


Thanks.

genkernel --menuconfig all is the correct answer to "How do I modify a genkernel kernel?".
Did you change any entries outside the Graphics support section?
Suggest posting a photo of the crash screen on a free photo site and posting the url here.
Suggest boot cd, mount gentoo partitions, enter chroot, nominally:
Code:
 mount /dev/sda3 /mnt/gentoo
mount /dev/sda1 /mnt/gentoo/boot
cp /etc/resolv.conf /mnt/gentoo/etc/resolv.conf
mount -t proc none /mnt/gentoo/proc
mount --rbind /sys /mnt/gentoo/sys
mount --rbind /dev /mnt/gentoo/dev
chroot /mnt/gentoo /bin/bash
env-update
source /etc/profile
export PS1="(chroot) $PS1"
then
Code:
emerge linux-firmware pciutils usbutils gentoolkit wgetpaste
lspci -k | wgetpaste
wgetpaste /usr/src/linux/.config
emerge --info | wgetpaste
post the url's returned.

General opinion would be that a manual kernel based on http://www.kernel-seeds.org is best. Unfortunately Pappy's site is down as I write this.

FWIW - his seeds page is mirrored at

kernelseeds.bloodnoc.org
kernel-seeds.audiodef.com
(and there may be others)

The answer to this specific question is, include the --no-clean option, as in
Code:
genkernel --no-clean --menuconfig all
This also has the effect of keeping genkernel from erasing all work products and starting completely over, which'll save you a lot of time while tweaking the kernel. This option (and many others) can be set in the /etc/genkernel.conf file. I recommend setting --no-clean in there so you don't forget and erase your in-progress kernel .config. You'll also probably want to set
  • MAKEOPTS
  • MOUNTBOOT
  • SYMLINK
Have a look around. ;)

Place it it /usr/src/linux, named ".config", and include the --oldconfig option on the genkernel command line just once. :)
