I'm trying to setup my raspberry pi as a second monitor (to something like synergy ) with my Debian laptop using x2x and I am unable to figure out what is going on. I tried following instructions from here, but I keep getting
x2x - error: can not open display :1.0
and other related problems.
Here are the links / guides I tried to follow:
First answer here: Can I use the Raspberry Pi as a second monitor?
Second answer here
Last answer here
Other than that, I'm stuck with my error messages. Could someone please point me to the right direction?
