Alt-SysRq-K is broken in QQ 12.10

[philinux]

Solved.
Sorry, mc4man. You were right. I was forgetting myself and trying it on a 12.04 machine.

ON th e12.10 machine, /proc/sys/kernel/sysrq is indeed defaulted to 172, and setting it to 1 re-enables SysRq-K to kill the X server. Perfick.

Does that interfere with reisub at all?

I don't think so. 1 was the default value in 12.04 anyway.
In 12.10 with the value set to 1, I just confirmed that K, B and O all have the expected effect. E dropped me back to a tty, which I don't remember happening before but I could be wrong there. U seems to do what it's supposed to (lots of read-only filesystem errors until I rebooted). I didn't try I or S, and I don't think R ever did anything visible anyway.

No. keyboard layout setting is removed in gnome 3.60

No, it is not. I just used it.

And re-eneabled CTRL+ALT+BACKSPACE.

What he was referring to I believe was g-c-c 3.6 & gkbd-capplet, ect. In that case there isn't any layout/options available anymore.
12.10 (default) won't be using g-c-c 3.6, what Ubuntu decides to do for 13.04 I've no clue

can you paste your gkbd-capplet version and gnome-control-center version?

Mine is:
gkbd-capplet: 3.6.0-0ubuntu1
gnome-control-panel:
1:3.6.0-0ubuntu1

No, it is not. I just used it.

And re-eneabled CTRL+ALT+BACKSPACE.

Thanks to your message, I downgraded to gnome-control-center 1:3.4.2-0ubuntu18, it's OK now.

help.

I've tried using all means to edit /proc/sys/kernel/sysrq. gedit says it cant save as it cant create a backup ans save anyway doesn't work. Nano seems to work but on reboot it's back to 176.

How are you guys editing this file?

With a command like this:

sudo sh -c 'echo 1 > /proc/sys/kernel/sysrq'

Writing to this pseudo-file is always overwritten by a reboot. The entire /proc directory tree is in the OS's imagination, they are not files on disk they are a view into the OS's inner workings.

As described by this post: http://ubuntuforums.org/showpost.php...38&postcount=6
You can set to reconfigure on reboot by editing /etc/sysctl.conf and adding the line:

kernel.sysrq = 1

Doh, of course. Memory lapse. Cheers.

Worky now.
