gsettings set com.canonical.desktop.interface scrollbar-mode normal
sudo apt-get remove overlay-scrollbar liboverlay-scrollbar-0.2-0 liboverlay-scrollbar3-0.2-0

apt-get
gets stuck, then there are two commands to free it:
apt-get -f install
dpkg --configure -a
apt-get install hplig hplip-gui simple-scan hp-setup #might have to manually tell it the ip-address of the printer
lpstat -p #find name of printer lpadmin -p <printer> -o usb-unidir-default=true
