Subject: [gentoo-user] How cam I get system to recognize MagicSysReq while in X gui?
Date: Tue, 18 Dec 2007 04:25:59
1 I've figured out how to force a hard lockup on my system, by trying to
2 log on to my ADSL service when the modem is switched off. Yeah, I know...
3 Patient: Doctor, it hurts when I do that.
4 Doctor: In that case... *DON'T DO THAT*.
6 During one such lockup, I discovered that Magic SysRq doesn't work in
7 X. For those of you who haven't heard of it...
8 less /usr/src/linux/Documentation/sysrq.txt
10 The feature that I wanted to access was the ability to force an
11 emergency sync of the disks before powering off the system. This would
12 require simultaneously pressing {ALT}{SysRq}s after which I want to
13 force a boot with {ALT}{SysRq}b
15 This does work in a true textmode, but not in X. Fortunately,
16 Reiserfs' journalling saved my neck, but I'd rather not have to shut
17 down a machine that hasn't been synced. Is there a way to tell X to
18 pass through the {ALT}{SysRq}<random key> combo?
