Hello,

I use a 1366x768 Laptop screen and need to clone that to a smartboard which is attached via VGA.
When I attach the smartboard (VGA), something weird happens: Setting the resolution on both screens works, but I got a whole new desktop on both screens!
That means:
(a) A new background picture (the plasma 5 default one). ok, that's not bad, but:
(b) my plasmoids on desktop are gone! (and that's bad!)

And it gets even more weird:
When I try to add my plasmoids to this new strange second desktop and unlock plasmoids, my normal desktop including plasmoids comes back to both screens. So I can't add plasmoids to that strange 2nd desktop which always appears when attaching VGA...

So to put it short, the situation is:
VGA attaches --> second desktop appears, where no plasmoids can be placed.

That is really not useful for me!

My workaround for now: I use the same xrandr command attached to a keyboard-shortcut that I used on XFCE4 before I switched to Plasma5:

Code: Select all

xrandr --output eDP1 --mode 1366x768 --output DP1 --off && xrandr --output eDP1 --mode 1366x768 --output DP1 --mode 1366x768

after that, the normal standard desktop including all plasmoids is on both screens.

But I would be happy to have that just by attaching VGA without getting to that weird second desktop. How is that possible?
Thank you!

I *think* what is happening is KDE4 used to start all screens at the virtual 0,0 when attached so they would overlap. For some demented reason they decided to screw this up as it is usual in software development and try to place monitors right next to each other (check your system settings it'll show) but when you switch with xrandr then it'll put to 0,0 as you didn't specify an offset. Your hotkey command might be a solution to my docking problems thanks I should've thought of that.
