Re: [PLUG] bash; anacron; wmctrl question

[Denis Heidtmann]

Well, the prize goes to Wes--adding  before the wnctrl
-k commands worked.  Now when the script is launched by anacron the zenity
test command minimizes all open windows and presents its dialog window.
When that window closes, either due to a user response or time out for that
window, the windows are restored.  Great.  This means that a notification
to the user that something went wrong or that  some action is required will
not be hidden behind open windows.  Now that I am assured that the zenity
notification method works, I can get rid of the zenity test command at line
14.

In summary, I have a script which anacron runs every day.  That script
checks whether it is time to run a weekly backup.  If so, it instructs the
user to click "yes" and turn on the backup drive.   If "no" or timeout is
reached the script closes to be run the next day.  If "yes" the backup
script is launched.  If backup is successful the date file is updated and a
notification to turn off the drive is launched. If the backup is not
successful for any reason, various error notification windows are launched.

If I had put  the backup script among the weekly anacron scripts, there
would be no way to postpone the backup for one day.  Not running the backup
would postpone the backup for a full week.

Thanks to all who responded with ideas and suggestions.

Re: [PLUG] bash; anacron; wmctrl question

[Denis Heidtmann]

I have presently export DISPLAY=:0.  I do not know what the : means, and
why would you choose 1 rather than zero?  Note that presently the window
does appear, but the command wmctrl -k does not seem to do anything.  I
will be giving anacron an opportunity tomorrow with Wes' suggestion added.

Re: [PLUG] bash; anacron; wmctrl question

[Denis Heidtmann]

On the $DISPLAY variable, I  thought that is what export DISPLAY=:0  was
supposed to do.  It must be doing something, since the zenity window does
appear on my desktop.  It is just that the wmctrl -k does not seem to
work.  I will be trying Wes' suggestion tomorrow when anacron gets another
shot at it.

How might I enable logging, and which log files?

Re: [PLUG] bash; anacron; wmctrl question

[Tomas Kuchta]

Thinking little more about it - you might be able to get around the access
permissions - to display stuff on other user's screens by using xhost
command as part of user's default environment setup at login.

That however is breaking the security - you can imagine how the desktop
would look if random users can display stuff on your desktop. Beside
annoyances, I can imagine fake terminals, browsers, etc. and windows
covering whole screen without the closing button.

Re: [PLUG] bash; anacron; wmctrl question

[Tomas Kuchta]

I do not believe that you will be able to open graphical window using cron.
The best you can hope for is sending notifications or emails.

If you have the strength to continue with random experiments. Try: export
DISPLAY :1
In your script before launching the window. Although that will likely be
blocked because the executing user is different than the user owning the
graphical environment.

The only sure way, I can think of, would be to use existing or write own
notification system. This would run after login, by the user and accept
your notification messages for displaying.

Hope it helps, Tomas
