I have changed my lock screen image for the second time.
The first time the image was accepted and displayed on screen locking.
But the second image, and the one I want to use from now on, will not display. All I get is a black background.
I did the change in the same way creating a new /usr/share/backgrounds/linuxmint/default_background.jpg
The new image is the same size as the first one, and it is a smaller size in Mb than the first one.
The first image was black and white, the new image is colour.
What could be causing this problem?

Re: Lock Screen Image
Well, for sanity-check, do it in the same way again for a copy of the image that works.I did the change in the same way
If it turns out okay, then your method is probably good. Try it again on the reluctant image. If still no-go, then it's time to figure out what is different or strange about this image. Check the permissions. Check the 'type' in properties -- like is it a PNG or JPG or what? The extension on the filename is not necessarily correct. As long as the image is not inappropriate you can upload it here for others to try too.
Also try another image of course.

They get you every time. I had checked the owner and group before I posted but forgot to check everyone else, and it needs to be set to read and it wasn't!ofb wrote: Check the permissions.
Thanks for the third eye.
Re: Lock Screen Image
Ran into the exact same issue myself (MATE with MDM, trying to set new background, and it wouldn't stick; turned out to be permissions error (Thanks, ofb). I'm a certified Linux Admin, so that shouldn't have slipped by me. LOLbananabob wrote:They get you every time.

Setting the permissions to 555 did the trick. (No need for 666 or 777, folks. 555 does it nicely.)
