I have Fedora 23 installed on a Lenovo E540 with the default Gnome 3 Desktop Environment. I was thinking of trying multiple Desktop Environments, so that I might see what are thee new breakthroughs. Basically I'm using Gnome for a long time.

What better way to try a new interface then just installing it along Gnome 3? So I've installed KDE using dnf groupinstall "KDE Plasma Workspaces" I was very surprised to find out that after the reboot KDE wold not work ...

What happened is that when I chose to log into KDE my screens changes and the Desktop Background appears the just in a few second I'm back to the log in screen. No matter how many restarts or how many times i try the result is the same.

  • Is the first time I tried to have multiple Desktop Environments on Fedora, is this something that happens often or is it because of fedora 23?
  • And why wold this happen, all seems very straightforwards.
  • Should I make a bug report and what should I write in it?
  • What is your experience in having multiple desktop environments on Fedora?

I have multiple DE in Fedora 23 including KDE, Gnome, lxqt, and fluxbox and they all work for me. Check your logs and .xsession-errors. KDE is sometimes buggy with my mutimonitors, so you can try mv .kde .kde.bak and log in again (corrupte kde configuration ?).

your problem sounds like the Fedora 23 gdm bug. gdm does not work for some Graphics card. In my case, I've ditched gdm and I use kdm instead. Install kdm. Disable gdm and enable kdm with systemctl command and reboot. I guarantee that kdm will work. Otherwise, you wait 1 ~ 2 weeks till the gdm bug fixed.

@kimbn - First, sddm is now default with kde in Fedora - see . Second, the OP is getting a graphical login.

Hello. This has happened to me multiple times on openSuSe Tumbleweed. The only way for me to log in was to press Ctrl + Alt + Backspace, Backspace (2 times backspace) to restart the session. After that I could login. But I had to do this at every login when using KDE Plasma

I had the similar problem.

In the ~/.xsession-errors file I found:

klauncher: error while loading shared libraries: **: cannot open shared object file: No such file or directory 
kdeinit5: Communication error with launcher. Exiting!

Identify the missing package :

dnf provides '*/'

And then install the package:

dnf install qt5-qtsvg

And now it works for me.

Thank you for posting this, I added some information. Although the behavior was similar, we do not have sufficient information from the OP to know if this the same or a similar problem. I would suggest you file a bug report as , IMHO, qt5-qtsvg should have been pulled as a dependency
