linux halt after a long time break
everyone knows that linux will enter power saving mode if you don't use it for a couple of minutes, and it will stop the monitor. but my redhat 8 is wierd, if I don't use it for a short time, like half an hour, I can get back to linux by moving the mouse, if the time is longer than an hour and a half(I think), it will halt! no matter what key I press, nothing happens, I can just see "Caps Lock" and "Scroll Lock" flashing all the time, the only thing I can do is to press the reset key on the cabinet. is this a bug?
