Hi!
I bought this Tontec 3.5 screen. 
There is some manipulation to enabled it as primary screen. The HDMI screen is primary so I have to switch it.
The problem is that the tutorial given in the box is for Raspbian and there are some changes.
I have to change config.txt. The file wasn't in the same folder but I find it.
So, i have to change /usr/share/X11/xorg.conf.d/99-fbturbo.conf and for now I didn't find it.
In this file, I have to change the primary screen.
How can i find this file ? I try a FIND command but it doesn't exist.
Anybody find a solution for Rasplex and a LCD display ?
Is that possible to install a Plex client on Raspbian ? Maybe it will be more easy for me ?
Thanks a lot.
