Configuring

2. 2. Configuring KDE Plasma Manager

   Edit the RC Config File /etc/rc.conf to Enable KDE Window Manager

   nano /etc/rc.conf

   
   Append inside the rc.conf:

   dbus_enable="YES"
   hald_enable="YES"
   sddm_enable="YES"
   

   Ctrl+x to Save & Exit from nano Editor.

3. 3. Enabling sudo Command

   Next is Important to Enable sudo for Normal User
   This because you Cannot Login into KDE Plasma as the root User.
   So to Edit the sudo Configuration File with Vi Editor:

   visudo

   Type “i” to Start Editing.
   And on the Root below:

   root    ALL=(ALL)       ALL

   Append your User’s Credential to Enable it:

   [MYUSER]    ALL=(ALL)       ALL

   Change [MYUSER] with your User’s Name in the above.
   Then Hit “Esc” and again “:wq” to Write and Quit!
   Finally, to Test your Setup:

   su [MYUSER]

   And try to Reboot your System:

   sudo reboot
