I assume there must be some new undocumented nonsense to get access to other users in wayland. In an Xorg display root display access works the same as it always has for me. I was wrong, it is documented: https://fedoraproject.org/wiki/Common_F25_bugs#wayland-root-apps Presumably f26 is still protecting users from themselves the same way. The fun thing about this whole urban legend of GUI apps being more insecure than any other kind of apps when run as root is that it appears to be simply taken as an article of faith. I have asked before for someone to point me the the big list of exploits that have happened because someone ran a GUI app as root, and so far all I've gotten is crickets. You'd think if this was such a well known problem that there would be at least one real world example, but I sure can't find it. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
