Talk:Using X without a Display Manager

The following excerpt from this script doesn't seem like the best practice. It's modifying the nix-store directly:

 #make the intel backlight helper setuid if it isn't already
 xf86videointel_path=$(get_pkg_path xorg.xf86videointel)
 backlight_helper_path="${xf86_video_intel_path}/libexec/xf86-video-intel-backlight-helper"
 if [ -e "$backlight_helper_path" -a ! -u "$backlight_helper_path" ]; then
      sudo chmod +s ${xf86_video_intel_path}/libexec/xf86-video-intel-backlight-helper
 fi
