Err... "AltGr"?
a.k.a Right Alt.
Whatever activates the "SysRq" key on your keyboard, usually "PrtSc" or "Print" on IBM PC keyboards.
You can also configure the key by writing a character to /proc/sysrq-trigger
See /usr/src/linux/Documentation/sysrq.txt for more.

Right Alt key? All right. So what would I hit to shut it down? AltGr-SysRq-K-S-U-B?
Yes. You hold Alt-SysRq and then press the other (lowercase) keys in order.
K means "kill all processes" S means "sync all filesystems" U means "unmount all filesystems" B means "do a hard reboot" O means "do a hard poweroff"
There are more options, but these are useful for system lockups.
It's advisable to wait a bit after the S and U combinations so they can complete.
Note you have to have this functionality enabled in the kernel config under "Kernel Hacking".
See /usr/src/linux/Documentation/sysrq.txt for more.

Yep. I enabled it in the new kernel I'm compiling. How long would you say I would have to wait for the syncing and unmounting to finish? And what exactly is a "hard" reboot? Not letting everything happily shut down?
I have another problem, though... My Gentoo live CD is not working. I put it in right when the computer turns on, but nothing happens. It doesn't boot. Doesn't boot from the hard drive, either. My old Knoppix CD still works, though. And I know this CD used to work fine... It is the one I used to install Gentoo in the first place. No scratches or anything. Well, there is a tiny nick on the edge of the CD, but it's on the top side, so it should not matter.
