"EggSMClient-WARNING **: Failed to connect to the session manager: None of the authentication protocols specified are supported"

Question

I am on ubuntu 12.10.

Every time that I try to open gedit on root this appears:

(gedit:3254): EggSMClient-WARNING **: Failed to connect to the session manager: None of the authentication protocols specified are supported

** (gedit:3254): WARNING **: Could not connect to session bus

Solution

Use gksudo for this:

gksudo gedit

That should do the trick.

Is it just a warning, or a fatal error preventing you from running gedit? (regardless, gksudo is the way to go)

Note that the messages shown in the Terminal are not really a problem, and all running gedit with & after it does is to suppress those messages. The underlying (extremely minor) issue that produces the messages is not fixed by doing that. @guntbert sudo gedit might make gedit not work when run as the non-root user. We we've discussed, I think it's not very likely to lock out local GUI logins, but I am not 100% sure. It might or might not be the practical cause of such problems.

-1 Ugh, detaching sudo from the shell is a terrible idea.
