gnomesu and sux no longer work after portage updates within the last month. gnomesu just hangs when any command requiring an X window is run. sux in a terminal works to switch to the root user, but it is not possible to start an X window from the root user account, and the follwoing warning is displayed when starting for instance nautilus: (nautilus:32503): GnomeUI-WARNING **: While connecting to session manager: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed. The problem seems not connected with the setup of permissions to use the X display, I have also tried xhost +localhost before switching to the root user. The error behavior with "sux" is exactly the same what I am obtaining when logging in as root user from a console with "su". I am not sure if this beahvior with "su" is expected. Anyway, everything seems to work ok when using "su -" instead. Note that the bug report is about "sux" and "gnomesu" which used to work correctly just one month ago. An error with gnomesu exists in the stable version 0.3.1 as well as in the testing version 0.3.1-r2. However, previously I have been working successfully with the testing version only. The error behavior is quite different between the two versions: The stable version hangs with the gnomesu window displayed, while for the testing version the gnomesu window vanishes as expected, but creates at stalled process. Reproducible: Always Steps to Reproduce: 1.Up-to-date Gentoo with emerge -uDN world 2.gnomesu from the menu, sux from a terminal 3.try to start with root permissions any program that requires a X window Actual Results: gnomesu window hangs. sux produces a warning, nothing else happens. (nautilus:32565): GnomeUI-WARNING **: While connecting to session manager: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed.

Gnome ====== When switching to the root user with sux, the described warning appears in Gnome after trying to start an application from the command line, but the desired application is then not starting up. KDE ==== For KDE, there is no warning at all, but the application is not starting up either.
gnomesu is depricated in favor of gksu. Can you try that, instead? Keep in mind, if you're using the sudo varients, they probably honor /etc/sudoers, which now nukes your entire environment by default. You may have to modify that to not do that. Adding sux maintainer.
Some more findings: 1) gksu has the same problem (in the terminal, the same type of error message is displayed, the gksu window hangs after pressing ok) 2) From a Google search, it seems that users of some other distributions, e.g. Ubuntu encounter the same problem, cf. (sorry, in German) http://forum.ubuntuusers.de/topic/70904/ 3) I have checked xauth and this seems to be fine when changing to super-user with sux. In fact, "xauth list" returns a valid "MIT-MAGIC-COOKIE" that is also available to the original user. However, there are is a new /root/.xauthXXXXXX file generated every time sux is called, whereby XXXXXX seem to be some pseudo-random characters and numbers. These files are not deleted, which is probably a side-effect of the problem. SUMMARY: ======== gnomesu, sux, gksu do not work any more for starting X window applications as a super-user.
This bug is dead old and sux and gksu/gksudo works perfectly here. If it's still not the case for you please reopen.
