...making Linux just a little more fun!

What is a better way to reboot your system in case it hangs? I mean
rather than three finger salute or kicking the power switch? 
Let's assume you have enable the magic SysRq before. Make sure this feature is compiled in the kernel (CONFIG_MAGIC_SYSRQ) and you enable it (echo 1 > /proc/sys/kernel/sysrq). Then when the disaster strike, you can try pressing these key combos in the following order: 1. Alt-SyRq-s (sync the buffer with the disk) 2. Alt-SysRq-u (remount all filesystem as read-only) 3. Alt-SysRq-e (kill all tasks, except init) 4. Alt-SysRq-b (finally, reboot system)
If your keyboard doesn't have SysRq, use PrintScreen instead. The way I do it is like this: press alt, hold, press sysrq, hold, then press s (or other key), then release them all. You might also try, press alt, hold, press sysrq, release it, press s or other key, release all.
In most cases, the above sequence could reboot your system better. But
if not, just fall back to the "traditional" one

That should be "alt".

Alt+SysRq+K is handy also, if you want to kill freezed SVGAlib application.
