I have Fedora 20 with Gnome DE. Gnome was default. Then I installed KDE and then I tried to log in to KDE. The screen goes off, then it says something like "starting fedora with linux.... heisenbug" (same way it says when fedora is trying to start), then again goes blank and returns to log in screen.

I tried this command:

systemctl enable gdm.service

I don't know what that command means, but I got it in our forum (here), and that made no difference.

I wanted to see how it goes with a different Desktop, so I installed "Sugar Desktop Environment" and it works fine, but still same problem with KDE.

I checked using the command :

rpm -qa|grep kde

I got the following results:

Hi,

I think this issue was caused because the KDE wasn't properly installed. While installing KDE in one of my system, the PC powered down. After booting it up, I found that it showed as KDE was installed, but it never booted. It did exactly same like before. So installed the fresh copy of Fedora with GNOME into the same system and unplugged it from power when the KDE installation was about to complete. I successfully reproduced the issue!!

So I reinstalled Fedora on both systems and installed KDE successfully using the command yum install @kde-desktop. Now I can load KDE without any issue.

Thanks to everyone.

So, when you reach a graphical login screen in Fedora 20, you're seeing a desktop manager. If you only use KDE with Fedora, you'll see KDM - the KDE Desktop Manager. If you're using the standard Fedora distribution which runs GNOME, you'll see the GNOME Desktop Manager (GDM). If you start with GNOME and install KDE afterwards, you'll still likely be logging in with the GDM unless you manually configure your system to use the KDM instead. So, I'm going to assume (unless you have other information) that you're seeing the GDM when you try to log in.

The command you listed is the command to ensure the GDM is enabled, and therefore capable of presenting you with the graphical login window. Since you are seeing the graphical login window associated with GNOME (at least, that's how it sounds to me from your post), you know the GDM service is operational.

The problem is likely with the GDM's ability to start up KDE since it sounds like you're describing an attempt to log into KDE from the GDM which fails catastrophically and forces your system to reboot, eventually returning you back to the GDM. If this is the case, we need the contents of the GDM log (/var/log/gdm/0.log is the most recent) and perhaps the X log (/var/log/Xorg.0.log is the most recent).

Take a look at those logs and see if you notice any text that stands out to you (mentioning errors or crashes, etc.). Feel free to post more of the output than less if you don't know what you're seeing and we'll be glad to help.

Hi, u r right. The default is GDM in my system. . But I have already tried changing it to KDM and the same issue happens in KDM.

Right, so I wasn't suggesting that you change your desktop manager to KDM. Did you happen to investigate the log files I mentioned (/var/log/gdm/0.log or /var/log/Xorg.0.log) and find anything relevant to the problem at hand?

Hi bitwiseoperator , thanks for replying. I don't know what to check..

/var/log/gdm/0.log is empty

/var/log/Xorg.0.log file has contents and I don't know what I should be checking there.

Shall I copypaste the log as an answer.. I couldn't do that in comments as it has lot of characters..

Edit: Hi, I have added the /var/log/Xorg.0.log to question as an edit.

Is there any easy way to force update all the packages for KDE in Fedora 20.

i think that the best option is downloads f20 with KDE, but in this problem you can type in terminal this systemctl status foo.service is the result is disable , you can enable this. or install other login manager

yum install lightdm

systemctl enable lightdm.service

systemctl disable gdm.service

reboot

$ sudo systemctl disable gdm

and then

$ sudo systemctl enable kdm

If this doesn't work, check http://fedoraproject.org/wiki/KDE#Command_line for help.

HTH.
