Thanks for the links I'll check things. Do you know how I find out if the
omputer has optimus or not? I see that the nvidia card I have (GeForce
940MX) is listed by nvidia with optimus technolgies does that mean I should
try following this
https://wiki.archlinux.org/index.php/NVIDIA_Optimus
and hope that it works?
I'm getting used to working with the touchpad without buttons (and its also
a touch screen and comes with the pen so I'm trying that as an interface).
Thanks
Oded
