Similar problem. I actually had updated to 18.04 beta, with no problems. The issue manifested itself after I upgraded to the final release yesterday. I don't think it's related to similar other bugs as I have libegl-mesa0 . I also cannot find any error message in the logs, seems that Xorg loads all of the HW acceleration libraries just fine, but for some reason gnome-shell runs on llvmpipe.
