this is supposed to be both a bug report and a 'any idea how to fix it?'-thread. I wasn't succesful finding this problem on this or any other forum. I'm posting this here because it only occurs to me on Cinnamon.
Acer 1810t laptop with HDMI out (Intel GMA 4500MHD GFX-Card)
LMDE12 32bit using Cinnamon
Samsung 40" LED TV
And here is what happens:
This is my desktop without my TV attached via HDMI:
Now I attach it via HDMI, and it looks just as it is supposed to:
When I unplug it again, though, my wallpaper is shifted:
And when I plug it in again, it stays like this, on both screens.
And nothing fixes this. Plugging and unplugging the TV keeps the shifted wallpaper. Restarting Cinnamon doesn't help. Changing the wallpaper doesn't help. I have to kill the X-server (ctrl+alt+backspace) and log in again to get the wallpaper back in order.
This only happens in Cinnamon, not in MATE. It seems like a bug to me, but can you gurus think of a way for me to fix this? It would be very appreciated.
