Using the Magic SysRq Key The SysRq key is located near the Scroll Lock key on your keyboard – the Sys Rq key is generally the same as your Print Screen key. The “magic” SysRq combination is Alt+SysRq. To use this key combination, your Linux kernel must have been compiled with the CONFIG_MAGIC_SYSRQ compile option – most Linux distributions will have this enabled by default. Assuming it’s compiled into your kernel, it can be enabled or disabled on a running system by changing the value of /proc/sys/kernel/sysrq. To check if it’s enabled, run the following command:     cat /proc/sys/kernel/sysrq If you see a “1”, the magic SysRq key is enabled. image If you see a “0”, you’ll have to enable it yourself by running the following command as root:     echo “1” > /proc/sys/kernel/sysrq Dealing With a Frozen X Server If your X server (the program that runs your graphical deskt...

* How do I use the magic SysRQ key? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ On x86 - You press the key combo 'ALT-SysRQ-<command key>'. Note - Some (older?) may not have a key labeled 'SysRQ'. The 'SysRQ' key is also known as the 'Print Screen' key. On SPARC - You press 'ALT-STOP-<command key>', I believe. On PowerPC - You press 'ALT-Print Screen-<command key>'. On other - If you know of the key combos for other architectures, please let me know so I can add them to this section. * What are the 'command' keys? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 'r' - Turns off keyboard raw mode and sets it to XLATE. 'k' - Kills all programs on the current virtual console. 'b' - Will immediately reboot the system without syncing or unmounting your disks. 'o' - Will shut your system off (if configured and supported). 's' - Will attempt to sync all mounted filesystems. 'u' - Will at...
