This is not a problem or anything I am struggling with. It's simply just making me curious.
How come when updating my display driver, a blank command-line shows briefly, before the desktop shows up again? I suspect this may boil down to how a display driver works in the first place?
If it makes any difference, I notice this when I update my nVidia display driver.
I do not mean a command-line window. The desktop disappears, replaced by a full-screen, blank, command-line. The screen goes black, with an underscore blinking. After 1-3 seconds, the desktop re-appears by itself.
