After upgrade to Ubuntu 18.10 I have noticed a strange behavior.
When I close the lid on my notebook, it goes in to suspend, as expected. But, when I am returning from suspend the desktop is visible, with all the programs that were latest used, opened.
To return from this state I have to lock the screen (Super+L) and then log in again, using my password.
The behavior is similar to bug#1532508, but the difference is that in my case the information stays visible after I open the lid on my notebook.
Is this an know issue/bug and are there any fix for this problem?
