After every installation of Ubuntu I try to get the GNOME 2 behavior back. This is very annoying and costs lot of time and research. Last months I tried xubuntu and xfce4. Both are very annoying and no real solutions for a productive desktop solution.
I haven’t used KDE for years because I always preferred GNOME. But yesterday I gave it a try and installed it by using the command:
sudo apt-get install kubuntu-desktop kdm
As you see I also replaced the broken lightdm desktop manager which really looked ugly in my multiscreen setup. After a reboot kdm started like a charm. I chose KDE Plasma session and logged in. After a few minutes of configuration everything looked really usable and worked out of the box. At least I can work with a default setup without hours of customizing. KDE you got a new fan!
Here my command to remove the old xfce and xubuntu stuff:
sudo apt-get autoremove --purge xfce* xubuntu* lightdm
Of course I’m NOT responsible if you break your installation by using the commands I posted here. I can only say “worked for me” 😉
