LinuxQuestions.org - Thread was not posted to forum

Hello.
I submitted a new topic to the Chrome OS forum, relating to my specific problem. I thought it was a fairly well rounded post however the thread has not yet been reviewed by a moderator.

There isn't any trace that I even sent the post in on my side. It was originally submitted more 24 hours ago and it has yet to appear in the forum. Yesterday I wrote same thread on Linux Software: same result, no posted.. :mad:

Could you help me? :)

Thanks a lot.
Best regards.

Beppe

My thread
_____________________________________________________________

Hello.
First, I am a beginner in Linux and my english is not good. :)

I have a ChromeOS system with Debian GNU/Linux 12 (bookworm).
I've installed some Linux App like GIMP, Thunderbird, Deja-dup (for Backup), Abiword.... They normaly wok fine.

I can try to run automatically at reboot (from Linux) Deja-DUp (to backup my disks).

I 've edit crontab and insert a line that invoke a script at @reboot option.
I've put echo instruction with labels in Crontab and in the script and I've seen both in internal mail.

But the program Deja-dup doesn't start. I've made a lot of attempts without success. I think because is not yet active the Linux graphic. Instead, if I run the script from terminal, the program Deja-dup start and run correctly...

I put sleep instructions in the script and in crontab to delay execution, without success.
I've also seen that $Display was "" instead of :0 at reboot execution. I've forced this value, but it doesn't work .

Below first the script and after the email reporting after the boot:

----------SCRIPT---------------
#!/bin/sh
sleep 15s
echo "Hello Beppe Start Shell"
echo "PATH"
PATH=/usr/bin:/bin:/usr/libexec/deja-dup
echo $PATH
DISPLAY=:0
echo "DISPLAY"
echo $DISPLAY
/usr/bin/deja-dup &
#!
#!deja-dup --backup
#!/usr/libexec/deja-dup/deja-dup-monitor &
#! wait
#!disown
#!
echo "Hello Beppe End Shell"

Hello Beppe Start Shell
PATH
/usr/bin:/bin:/usr/libexec/deja-dup
DISPLAY
:0
Hello Beppe End Shell
?

----------------

Sometimes I also have the error: (org.gnome.DejaDup:1129): Gtk-WARNING **: 12:52:27.166: cannot open display:

I've also try to create /etc/rc.local and run deja-dup from this file, but it doesnt' work.
Finally I've tried to create org.gnome.DejaDup.desktop in folder /home/bepp662/.config/autostart, but without success...

Both, rc.local and folder autostart, weren't present on my system and so I've created both, but probably my system doesn't work with these 2 options....

Ah... I've also tried to run Abiword at reboot... same results :(

Have you any ideas how to run deja-dup at reboot?

Thank you in advance.
Beppe
