This is about linux... Ubuntu 18.04 if it matters... Dell Inspiron laptop if it matters...
I'm finding that when I do "xrandr --output eDP-1 --reflect xy" it seems instantaneous, but when I then do "xrandr --output eDP-1 --reflect normal" (to put it back) there's a delay of something like three seconds, during which time the screen is black. If the screen is already in normal mode, the latter command does not have a delay. The same thing happens if I do this operation to my external monitor (HDMI-1) instead of to the laptop screen (eDP-1) except that the delay is slightly longer. (Same thing with "--rotate inverted" followed by "--rotate normal".)
Why would this be, and is there some way to flip the screen without a long delay?
