Some additional information: - The same thing happens on a very old Dell Inspiron (I think) desktop, also with Intel integrated graphics, that my wife uses. (But the two Precision workstations are less than 1.5 years old and the other machine is definitely more than 5 years old. ) - The problem is independent of the display manager (I'm using sddm, but I tried with gdm, too) and, mostly, the desktop. With Gnome, it comes back from the initial screen blanking when a key is pressed, but if it sits longer it will reach a state where it's necessary to switch to a VT and back to get back to the X display. - The machine is seeing other key events, too, but they just don't wake up the display. If I leave the focus in, say, a konsole or a Gnome terminal and let the machine blank the screen (waiting long enough on Gnome), typing ordinary text won't bring back the display but the typed material shows up when I switch to a VT and switch back. - I tried with a new user, in case this had something to do with settings getting upgraded from F23 to F24 or some other misconfiguration in my account. But the same thing happens. Is anyone else seeing this? Should I file a bug? For X, for the Intel driver, or something else? George
Yes, I see this also. I have a Dell desktop with AMD graphics. I have turned screen blanking off, so that my screen saver runs all the time after my machine goes idle. I hadn't discovered that switching to a VT and back would activate the screen. I will have to give that a try.
