Hi,

I tried the following two things after filing the bug.

1.
------------
As screen is working properly in Fedora 24 and 25, I installed Fedora 25 version of screen.

$dnf remove screen
$dnf install http://ftp.jaist.ac.jp/pub/Linux/Fedora/updates/25/x86_64/s/screen-4.6.1-1.fc25.x86_64.rpm
------------

2.
------------
Download, compile and install GNU screen from source.

http://ftp.gnu.org/gnu/screen/screen-4.6.1.tar.gz
------------

GNU screen is getting killed after these 2 steps also.

The above issue is a known issue in systemd.

https://lists.freedesktop.org/archives/systemd-devel/2016-May/036583.html

"systemd-logind will now by default terminate user processes that are part of the user session scope unit (session-XX.scope) when the user logs out."



Hope there is some fix by either systemd or screen teams.

thanks.
