Alright alright - lets see if it now bootsup in the graphic UI; sudo reboot now =)
That also helped somone else on the forum sudo pacman -S video-hybrid-intel-nvidia-bumblebee also worth trying.
If that wasnt it I would now go and adjust the wrong directory permissions so
chmod 755 /usr/
chmod 755 /usr/lib/
chmod 755 /usr/bin/
chmod 755 /usr/share/
chmod 755 /usr/share/doc/
chmod 755 /usr/lib/systemd/
chmod 755 /usr/lib/systemd/system/
I have no clue why or how they changed but 700 means ONLY root has access read/write/execute but also other "users" need to at least read and execute in those directorys - so that is what 750 does = it means user=rwx group=rx others=nothing - not sure if thats fatal but could be corrected.
-= sadly its 10:30pm now - i need to see my bed - all the best luck for tnight =-
