[Trisquel-users] Moving to Trisquel

[beratpostalci]

Hi everybody, I'm a Ubuntu user and I want to move to Trisquel and want to  
use it as main OS. My laptop model is Dell xps 13 9350 and I have not any  
main problem with Ubuntu. One the reason that I want to move to Trisquel is  
using %100 Free Software.
So
I tried Trisquel as live cd and couldn't adjust screen resolution and also  
WiFi was unavailable. When I completely install it, are these problems can be  
solved?
Can anyone help me?
Thanks in advance.
