I installed optimus manager and qt from the aur

i though i added the kernal parameters to mkinitcpio.conf but now that i look at it it is empty

first failure, if you had read the link before acting you had recognized that i gave the advice to install the optimus-manager from the normal packages and not the aur. read first before acting.

i did read that but when i checked it did not exist

  sudo pacman -S optimus-manager                                                                      
error: target not found: optimus-manager
