On my laptop, disabling the keyboard shortcuts associated with the SysReq key didn't do it. I also had to modify
Some Linux distributions come with the magic sysrq disabled as a security measure, considered by some to be misguided. You'll see in */etc/sysctl.conf * kernel.sysrq = 0 Change this to kernel.sysrq = 1 and run sysctl -p You should always check for this on a new Linux system before running into a freeze that makes you wish magic sysrq was working. from http://en.wikipedia.org/wiki/Magic_SysRq_key and THEN it worked. Is this disabled in Ubuntu intentionally?
