Hi, I've recently installed linux mint on a pavilion dm4, and it's running smooth, really nice.
Just recently the background started going black when I go into the workspace switcher, or to the open window selection screen (I don't know what it's called, you get there by pressing ctrl+alt+arrow key down), or when I'm alt-tabbing through the windows, so basically anywhere but on workspaceX itself the background just goes black.
I haven't changed anything about the settings and I didn't do an update before rebooting the last time. I know this might not be appropriate to say about a system but.... it "just" happened, dare I say it, for no reason, it appears.
Is there a quick fix for this?
Would very much appreciate some help with this.
