# unless we specify slick-greeter, it's going to default to unity-greeter which pulls in
# parts of Unity also

# - lightdm is a display manager (= GUI for logging in to your desktop)
# - rofi is an application launcher
# - xwallpaper might not be always required (once hautomo-client can set wallpapers without it)
# - ttf-ancient-fonts because emojis didn't render (https://www.omgubuntu.co.uk/2014/11/see-install-use-emoji-symbols-ubuntu-linux)
# - fonts-noto-color-emoji to get colored emojis for i3 workspace symbols
# - gvfs-backends = Samba working in thunar
# - gvfs-fuse = GVFS files to work in non-GIO (= POSIX) programs
# - xdg-utils = xdg-mime (for setting default programs for file types)

# before for some reason lightdm had to be installed in a separate "$ apt" call, otherwise gdm3
# would get pulled in. now after I removed something from here it gets pulled in anyway. JFC I
# tried to research which package pulls it, I couldn't figure it out and now we have conflict
# because we have 2 managers, and now we've to fix it. UGH!
