Public bug reported: Last missing piece (after hacking around kernel issues) for me in getting hybrid graphics working was to change this line in the hybrid-power script to match my eDP panel:
lvds=$(xrandr | grep -i "lvds" | head -n1 |cut -d " " -f 1) the eDP line for me is eDP-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm I changed it to read lvds=$(xrandr | egrep -i "lvds|edp" | head -n1 |cut -d " " -f 1) maybe a more conservative regexp is more appropriate like " edp-[+-9]" to reduce possibility of false negatives.
