When I am running xfce4-power-manager and try to change the backlight brightness using the media keys it only jumps from 100 to 45. If I try to set the backlight brightness manually using xfpm-power-backlight-helper it never changes the brightness. If I'm not running xfce4-power-manager I can set the brightness fine with the media keys but it only changes it in increments of 1.
