[roky005]

please HELP!! I have been trying to fix a bug in Linux for days! and cant get a solution, The problem is that I cant open xfce4 It says that another window manager (Xfwm4) is already running on the screen. 0.0
To replace the current window manager, try "--replace."

I tried deleting xfce4 files but it refused by every way I tried doing --replace I went from Ubutune to Dubai, and several things, I cant remember, I tried more than 30 codes to fix it; I tried updating; I tried almost everything. Please, somebody, help me. Im about to leave this Linux thing because of this (Im a beginner). Please, if you have a solution, help me. Im exhausted. I searched everywhere. write your solution clearly with explanation, because, as I said, Im a beginner and dont understand that much of this OS
