Ever wonder what the Sys Rq key on your keyboard does? Not a lot I hear you say!
According to [1]
“There is no standard use for the key. The BIOS keyboard routines in INT 16 simply ignore it; therefore so do the DOS input routines in INT 21 as well as the keyboard routines in libraries supplied with high-level languages. “
Wiki also suggest that.. ” it was intended to be available as a special key to directly invoke low-level operating system functions with no possibility of conflicting with any existing software“
Well here is one super cool feature for Linux when your screen locks up (not often I know) .
hold Alt + Sys Rq while typing REISUB
Typically use this when Alt + F2 etc doesn’t work nor does Crtl + Alt + Backspace
For laptops add the Fn key !
Hmm.. looks like you’re still using that keyboard from 1981. Good year. And did I read correctly? “Linux.. locks up”!! That’s a line you don’t hear the fanboys say often!
