When logging in lubuntu 12.04, my background image always disappears, leaving the screen with color only and then I have to go to definitions and set the image in the background again.
I notice that this does not happen with low-resolution images, only with high ones, but also happens with images that fit my screen resolution (1280 X 720).
Any ideas on how to fix this?
The image remains at it's location, but on the desktop preferences, the pathway to the file location is lost and set to none.
Maybe image's path didn't have the right permissions, try to move one to your Pictures directory and tell me if it still get lost on new sessions.
If that's the problem you could set the rigth permissions to your images's folder running:
and through the properties dialog set permissions for your user to read-whrite that directory, remember to press apply to enclosed files button.
I had the same problem. When I login, I get a black screen as if the image has been deleted. Then I figured out that it was a permission issue. So I went into the permission tab, and changed Group, and Other permissions to Read and Write, and that fixed it.
Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command below.
When it comes up navigate to
/usr/share/backgroundsand change the permissions from the permission tab.
