Don't run as root either! Run it as plain amanda, even if you have to
stick it in a test script and add it to amanda cron to kick it off.
No, since they've built a paranoid security wall between me and anybody
else, I'll run it as me.
Well, that is sucky :(
For the display issues earlier, try one of these:
export DISPLAY=:0
export DISPLAY=:0.0
Under your username do:
echo $DISPLAY
and I’m guessing use that. Mine is “:0”, the :0.0 was used in a cron entry
itself*, so probably not the one to use.
This is from an old bash script I ran in root cron that needed to also start
something as myself. It was on a Ubuntu 14.04 box, it’s Debian based but
might not be the exact syntax anymore.
export DISPLAY=:0
sudo -H -u michael bash -c '/usr/bin/progname &'
As long as you have the right sudoers entry (it looked like you had way
overkill, but it should work), running the same in the amanda script should
work. I’ll guess this should be the full syntax of the lines you need:
export DISPLAY=:0
sudo -H -u gene bash -c '/opt/trinity/bin/dcop kmail KMailIface
pauseBackgroundJobs'

This second URL showed me how to edit the sudoers file and add this:
amanda ALL=(ALL) NOPASSWD:/opt/trinity/bin/dcop
But it still fails:
root@coyote:~$ su amanda -c "/opt/trinity/bin/dcop --user gene
--all-sessions kmail KMailIface resumeBackgroundJobs" >do backup stuff<<
sudo -H -u gene
bash -c '/opt/trinity/bin/dcop kmail KMailIface
resumeBackgroundJobs'
HTH,
Michael
* Cron entry was like:
export DISPLAY=:0.0 ; /home/michael/common/bin/bashscript.sh
