Linux Tricks
Color change when connected remotely
Problem: after ssh to linux machine from macbook laptop, it keeps asking about some color settings (create color profile etc), and keeps asking for password; none of passwords actually works, and it keeps asking again and again.
Fix: on linux machine, create file /etc/polkit-1/localauthority/50-local.d/45-allow-colord.pkla with permissions 644 and following contents:
[Allow Colord all Users] Identity=unix-user:* Action=org.freedesktop.color-manager.create-device;org.freedesktop.color-manager.create-profile;org.freedesktop.color-manager.delete-device;org.freedesktop.color-manager.delete-profile;org.freedesktop.color-manager.modify-device;org.freedesktop.color-manager.modify-profile ResultAny=no ResultInactive=no ResultActive=yes
