Does not work, hard lock as I said.
Alt-SysRq reisub ??? At this moment, I do not remember what the default setting is for Alt-SysRq is. I know it is set to limited functions because of its power. You can find out with: cat /proc/sys/kernel/sysrq If you see a "1", the magic SysRq key is enabled. If you see a "0", you will have to enable it yourself by running the following command as root: echo "1" > /proc/sys/kernel/sysrq If you see another number, that means it is partially enabled, but some SysRq functions are disabled. Alt-SysRq-r takes the keyboard out of raw mode and control of it away from the X server. Alt-SysRq-k kills all programs on the current virtual console, including X. To cleanly restart a locked-up system, you can use: Alt-Sys-Rq with the keys reisub but pause for several seconds between each key. r puts the keyboard into raw mode, as I stated above. e sends the terminate signal to all processes, asking them to end gracefully. i sends the kill signal to all processes, forcing them to end immediately. s flushes data from your cache to disk. u remounts all file systems read-only. b reboots your computer. How do I remember this sequence for when I need it? Simple: Spelled backwards, it is "busier". I want the opposite. ;-) -- -Gerry Makaro aka Fraser_Bell on the forums, IRC, and mail at openSUSE.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
