Singe User (is from the kernel) you select the boot option via grub

People refer to this as "Maintenance Mode" although to be frank every gentoo
system is always in maintenence mode (kinda like perpetual beta)

http://www.redhat.com/docs/manuals/linux/RHL-7.3-Manual/custom-guide/s1-rescuemode-booting-single.html

It's the same idea just a diffrent distro;


Once you are in single user mode verify all mounted partitions:
#mount

Then navigate to your xorg.conf; (under /etc/)
and edit it to fix your issues or

Navigate to your home directory
/home/~username# and change the way you login by editing the approriate
files (depending on your x display manager)

Or conversly, if you are using a live cd:

1. mount your partitions a
2. ch root into your Gentoo install (you are now in single user mode)
3. Make the appropriate edits

as always your milage may vary; HTH
