Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. change value for DESKTOP in /etc/sysconfig 2. re-start X 3. Display Manager is still GDM Actual Results: Display Manager is still GDM Expected Results: Display Manager should be KDM Additional info: This already happened in Red Hat 8
Sorry, but you're mistaken here. There are two variables involved. DESKTOP - selects which desktop environment you wish to use - GNOME/KDE/etc DISPLAYMANAGER - selects which display manager you wish to use - xdm/kdm/gdm This is the way it has always worked, and it is fully documented in the manuals. If you want a different display manager than what you're given by default, then you *MUST* set DISPLAYMANAGER. prefdm is doing the right thing. Closing NOTABUG.
