I just installed Raspbian lite on my RPI 3. I only need to run Chromium so I do not need a desktop environment. Here's the screen I use : https://www.waveshare.com/wiki/3.5inch_RPi_LCD_(B)
What I tried:
I installed xserver-xorg and xinit. My plan was to run
startx chromium-browser on startup.
However, I cannot run X because it throws me the following error:
no screens found, event if I installed the drivers and I see text on it.
xrandr --display :0 tells me
can't open display :0.
Any idea ?
