I setup Compiz for my Xubuntu 17.10 based on the answer here: How do I install Compiz in Xubuntu?
sudo apt-get install compiz compiz-plugins-main compiz-plugins-extra
sudo apt-get install compizconfig-settings-manager
And attempted to start Compiz like this:
perret@perret-ThinkPad-E460:~/Desktop/Test$ compiz --replace

However even if the window decoration is enabled it seems that I end up with no windows decorations...
I checked the answers here: Compiz in XFCE4- Ubuntu-17.04: Setup progress
How can I fix that?
