I have done a clean minimal install of Ubuntu 20.10 in a VMWare Player virtual machine, running on an Intel Core i9 based PC.
I would like to know which compositor is used by default.
I am using the default desktop, which I think is Gnome.
Possibly it is mutter, as ps -ax | grep -i mutter, shows:
78825 ? Sl 1:52 /usr/bin/Xwayland :0 -rootless -noreset -accessx -core -auth /run/user/1000/.mutter-Xwaylandauth.GPDI20 -listen 4 -listen 5 -displayfd 6 -listen 7
99042 pts/3 R+ 0:00 grep --color=auto -i Mutter
Please can someone confirm if it is mutter, or if not, which one is used?
