In company I use a licensed enterprise web app written in Java. So far I used it only on Windows. Not long ago I was able to install it on Ubuntu as well. Recently I discovered Fedora . And i try to move all my stuff on this distribution, including work stuff. When I try to install that app on Fedora, I get such an error :

    It's an X11 error, so you'll either need to a) turn off Java's use of X11 b) make X11-from-root work or c) login as root to an X11 session. The chmod 777 * instructions from the install guide do not inspire any sort of confidence in the quality of this software, though. – thrig Jun 22 '17 at 17:34

It is a Wayand problem. So, I clicked the gear on the login screen, after I have clicked my username. Then I selected "Gnome on Xorg" option. Finally I provided my password and it started Xorg session. Installation worked.
