Hi. I also have this problem on my DELL Optiplex AIO 9010 running Ubuntu 16.04.5 LTS. And "Yes I know that 16.04 is no longer supported" ... however it seems that if you upgrade to 18.04, it does not solve the problem and in fact makes it worse !! At the moment, I get this message after my desktop has been sleeping, click on it and the usual login prompt appears whereas with 18.04 it seems that we cannot switch to the login screen without pressing CTRL-ALT-F1.
