For quite a while now I've been unable to use TDEsu to open utilities that require root access, e.g. TDM configuration. TDEsu freezes after I enter the root password and press Enter. When I run it from the command line I see
tdesu: WARNING: Daemon not safe (not sgid), not using it.
Looking at /opt/trinity/bin/tdesud, I saw that indeed, it was not sgid, so I set that bit; but it still hangs, albeit without the message. I see that there are four programs associated with this function:
-rwxr-xr-x 1 root root 59912 2019-03-18 15:53:08 /opt/trinity/bin/tdesu -rwxr-xr-x 1 root root 14544 2019-03-18 15:37:31 /opt/trinity/bin/tdesu_stub -rwxr-sr-x 1 root root 55440 2019-03-18 15:53:08 /opt/trinity/bin/tdesud -rwxr-xr-x 1 root root 72200 2019-03-19 15:10:26 /opt/trinity/bin/tdesudo
Should other bits be set for one or more of these? Is there a missing entry in /etc/group? What else should I look for? N.B. I have tried reinstalling the package containing TDEsu, but that hasn't helped.
