[gentoo-user] How cam I get system to recognize MagicSysReq while in X gui?
I've figured out how to force a hard lockup on my system, by trying to
log on to my ADSL service when the modem is switched off. Yeah, I know...
Patient: Doctor, it hurts when I do that.
Doctor: In that case... *DON'T DO THAT*.
During one such lockup, I discovered that Magic SysRq doesn't work in
X. For those of you who haven't heard of it...
less /usr/src/linux/Documentation/sysrq.txt
The feature that I wanted to access was the ability to force an
emergency sync of the disks before powering off the system. This would
require simultaneously pressing {ALT}{SysRq}s after which I want to
force a boot with {ALT}{SysRq}b
This does work in a true textmode, but not in X. Fortunately,
Reiserfs' journalling saved my neck, but I'd rather not have to shut
down a machine that hasn't been synced. Is there a way to tell X to
pass through the {ALT}{SysRq}random key combo?

the 'best' sequence is e-i-u-b (u = remount ro also syncs.. and leaves the fs
in a clean state).
To get the keyboard back from X try K (to sack X) or R (to pry it out of X
cold, dead fingers).
Another thing you can try: add something you want to be done (like switching
to a vt or a certain sysrq-key) to your acpid config and let acpid run. If
the keyboard hangs, just push the power button ...
for example:
event=.*
action=chvt 1
in /etc/acpi/events/default switches to vt1 if you push the power button.
Pretty usefull, if X is in deep shit mode again.
