This page shows you how to troubleshoot issues with your Funtoo Linux installation.
[edit] boot failure
If you did not get a login: prompt, it's possible that your install was not successful. You can reboot from the live CD and bind-mount your existing installation without repartitioning or recreating filesystems, chroot inside, and then check your system to ensure everything is configured properly:
# mkdir /mnt/funtoo # mount /dev/sda4 /mnt/funtoo # mount /dev/sda1 /mnt/funtoo/boot # cd /mnt/funtoo # mount --bind /proc proc # mount --bind /dev dev # cp /etc/resolv.conf etc/ # env -i HOME=/root TERM=$TERM PATH='/bin:/sbin:/usr/bin:/usr/sbin' chroot /mnt/funtoo
Once you are done making changes, leave the chroot, unmount mounted filesystems, and reboot:
(chroot) # exit # umount /mnt/funtoo/boot /mnt/funtoo/dev /mnt/funtoo/proc /mnt/funtoo # reboot
If you continue to experience difficulties getting Funtoo Linux to boot properly, please ask for help in the forums.
[edit] Debugging system startup
/etc/rc.conf contains system settings related to the system initialization scripts. If you are experiencing problems with the system startup scripts, you may find it beneficial to set rc_logger to YES. This will instruct OpenRC to launch a logging daemon to log the entire rc process to /var/log/rc.log.
[edit] Graphics Corruption at boot
If you experience graphics corruption issues at boot time, you may be experiencing an issue with the Kernel Mode Setting subsystem, known as KMS. To resolve this problem, boot from the live CD again following the steps above. Then, from within the chroot, edit /etc/boot.conf and add the line "params += nomodeset" to the "Funtoo Linux genkernel" section. It should now look like this:
"Funtoo Linux genkernel" {
kernel kernel[-v]
initrd initramfs[-v]
params += real_root=auto
params += nomodeset
}
Now, save your changes and run boot-update:
(chroot) # boot-update
Now, exit the chroot, unmount filesystems and reboot following the boot failure instructions.
