If you check /etc/X11/xdm/Xresources, you'll see a couple of keys
defined:
xlogin*login.translations: #override\
Ctrl<Key>R: abort-display()\n\
<Key>F1: set-session-argument(failsafe) finish-field()\n\
Ctrl<Key>Return: set-session-argument(failsafe) finish-field()\n\
<Key>Return: set-session-argument() finish-field()
As you can see Ctrl-R is abort-display, which kills the xdm server. If
you then set up things so that after that xdm terminates a shutdown -r now
is executed, you're set.
It would also be possible to define Ctrl-Alt-Del for this, ofcourse. Only
I don't know what the definition of that would look like, probably something
like Ctrl<Mod>Meta<Key>Delete: abort-display or so.
The easiest way is then to create a script in /usr/local/bin called say lxdm,
that looks like this:
#! /bin/sh
/usr/bin/X11/xdm --nodaemon
/sbin/shutdown -r now
sleep 10
And then you call this from /etc/inittab in runlevel 5:
x5:5:respawn:/usr/local/bin/lxdm
Instead of the standard xdm, so turn off the standard xdm first.
All this results in Ctrl-R at the xdm prompt rebooting the machine!
