<b><u>Other Settings</u></b>

Display Manager:
If you installed gnome, choose gdm. If you installed kde, choose kdm. If you \
installed anything else specified in XSession, choose xdm.

Console Font:
You probably don't want to mess with this.

Extended Keymaps:
You probably don't want to mess with this.

Windowkeys:
If installing on x86 you are safe with Yes, otherwise you'll probably want to \
say No.

Keymap:
This defaults to "us" if not set (recommended).  If you don't want an English \
keymap, choose it from the list.

XSession:
Choose this only if you didn't choose gdm or kdm from the Display Manager list.

Clock:
If you chose a local timezone, you'll want to choose "local" for the clock \
setting. Otherwise if you chose UTC in the Timezone screen, choose UTC here.

Default Editor:
Pick one.  Nano is the default and recommended.
