A few weeks back I upgraded my desktop from F21 to F23 using instructions
online and using 'dnf' to carry out the upgrade.
Unfortunately I don't have the URL of the web page I used, but the upgrade
worked exactly as indicated and no errors occurred.
After the upgrade and reboot I logged in to find that I was in GNOME.
I tried logging in again using KDE but it wasn't available. I eventually
found out that it was no longer installed. I eventually found the command
dnf install @kde-desktop
which then gave me the option log logging in using the session type
of 'Plasma'. However, after I log in all I get is a black screen and the
mouse pointer. No matter how log I leave it, nothing happens and all I can
do is Alt+Ctrl+Del to log out
Can anyone give me ideas how to fix the problem. I really don't want to do a
fresh install unless I have to (feels too much like a Microsoft style
solution)
