When I click on a background in the wallpaper selector, the picture of it shows up on little preview window inside of wallch. However, the actual unity background does not change.
I tried clicking on "Start," and the timer starts running, but again, the background is not affected by wallch---it stays on whatever I set it to be prior to running wallch. I also tried clicking "Next," etc. No effect.
Just anecdotally, I tried wallch on a 14.04 system without an nvidia driver (running unity 2D) and it worked fine. The problem occurs on a system which is running compiz and the nvidia 3D driver.
It detects Unity.
