Hello i wanted to ask how to switch off the tourchpad on the notebook because i use an external mouse. I do not find any option for this in the GUI under "mouse" someone has a clue which conf. i should edit ?

To keep it at boot add the following in /etc/sysctl.conf.

Thanks it worked again !!! Great !!! btw i had to install nano via pkg install nano seems not to be preinstalled in Ghostbsd but i use this editor since ages under Linux ! But i must realy thank you for this great support.
My old notebook performs so great and fast -and this Mate Desktop is looking realy great.
Most userfriendly BSD i have ever seen !
