I recently submitted a post regarding booting Mageia into a GUI as root. Something generally regardewd as a nono. After a nunber of posts to this query, there seemed no solution to this seeming anomalour boot option. Except, not to use it! Still curious, on a Thinkpad loaded with Mageia from a number of years ago, I tried the same login sequence as root. it worked. I could login as root in a GUI. I had thought that the relative who had built the install, had performed some action that allowed such an effect. His last re-boot before sending me the machine had been to boot under root, so the next re-boot had been with the same user. Admittedly, it did require roots password, but it is generally acknowledged, that running root in a GUI is a nono. Some years ago, on this forum I was flamed for mentioning running konqueror as root to get around a problem with remote connection with SMB to install files and manage a Drobo unit, was only possible as root. I did, subsequently find a solution to this on a Ubuntu forum, and as a normal user I now have full access rights to such units mounted uning Ciffs.
But surely, if a graphical login as root is a bad thing, it should not be possible, as a matter of course.
