Title:
Wallpaper does not resize correctly when adding external display
Status in xorg package in Ubuntu:
Confirmed
Bug description:
When I add a second (external) display to my laptop (Dell Latitude)
the wallpaper/background is not resized correctly.
1. just an internal display with a resolution of 1366x768
2. adding an external display with a full HD resolution
Adding the external display results in
- the wallper is shown in the upper left corner of the external display
(probably with the resolution of the internal display.
- The rest of the screen is filled with random segments of windows that have
been shown at these positions before
- the internal display does not show any wallpaper (completely black)
Additionally it looks like the left side panels (one for internal and
one for external) are drawn over each other on the external display.
See attachment Auswal_001.png
Deactivating the internal display does not change anything
Locking the screen shows a correctly resized wallpaper in the
background.
