Hello.
I have a Dell laptop, for which I have 2 docking stations (at home and
at
work), both with additional monitor connected. The monitors differ in
resolution. I do not turn my laptop off, I only suspend it to RAM, when
it is
not used.
Let's consider such scenario: laptop is docked at home. Xrandr shows
available
resolution for external screen properly. I turn off the external output
(xrandr --output VGA1 --off), then I suspend it, undock and take to
work,
where I dock again to another docking port and wake it up.
The problem is, that the laptop does not re-read the resolution
configuration
then. it shows resolutions from the monitor which I have at home, not
at work.
I think that after the machine wakes up, it gets no "display changed"
message,
which is pretty logical. ButThen The only way I can have the data
"fixed" is
to unplug the monitor physically and plug it back. And I dont like such
solution, that's not what docking station is for.
Can I somehow make xrandr refresh its readings?
