Fighting with computers

For an upcoming Art project, I needed to make a few things using a Raspberry Pi 3. And while I have not yet figured out a neat way of setting the wifi configuration wirelessly (as they did for ESPlink ), I have made some progress on other fronts needed and configuration-related. First thing on the list was to make the RPi3 work with a 3.5" color LCD with touchscreen .  It was simple once I followed the right set of instructions .  Not sure if the display can be kept on while using the HDMI output but guessing no I removed the HDMI output for all my testing. This LCD display is 480x320 resolution and it can work as a minimum display for both text console and X11. You just do not want to browse the web with that. While the display worked nicely, I wanted it to be kept working all the time but the power saving settings disabled it after being idle for a while. A bit of googling led me to a nice solution: to add the line xserver-command=X -s 0 dpms to /etc/lightdm/lightdm.conf
