If you install and try to run the current Atom release on Fedora 25 you may find that it will not start, but also won’t output any error. It just won’t open.
EDIT : This issue is already fixed in the latest atom releases.
Running atom on a terminal will show you why:
/usr/share/atom/atom: error while loading shared libraries: libXss.so.1: cannot open shared object file: No such file or directory
This solution for this is simple. Just install the following package:
$ sudo dnf install libXScrnSaver
Seems that this RPM build is missing some dependencies. The bug is already reported here.
