I have the screen coming back on at resume, with a script in
/etc/pm/sleep.d/02screen based on these suggestions (details at bottom
of this email).

But there's a big problem -- xrandr changes the nominal screen
resolution when the display is disabled, it sets it to 320x200 which
appears to be some sort of built-in minimum.  Then even though the
resolution is changed back again when the display comes back on, many
applications have already reconfigured themselves and are now squashed
into a tiny space in the top-left corner.  Even if they were minimized
at the time, they still come up tiny when restored.

The output from xrandr --verbose is:

crtc 0: disable
screen 0: 320x200 84x52 mm  96.25dpi

when disabling and

screen 0: 1920x1080 499x280 mm  97.69dpi
crtc 0:    1920x1080   59.9 +0+0 "DP3"

when re-enabling.  Anyone have any ideas about this one?
