You might want to make sure that you use the run script to start the app. The important lines are:

sudo chmod 0664 /sys/class/backlight/rpi_backlight/brightness
sudo chown root.pi /sys/class/backlight/rpi_backlight/brightness

Autostart

Example Can4Eve.desktop file to be placed in .config/autostart of your user. Please adapt the exec line to where you installed can4eve
