No desktop session found: no notification icon

[Jean-Peer Lorenz]

Originally reported by BlueLight on 2011-01-01. I've split this bug https://bugs.launchpad.net/sbackup/+bug/696183 into two.

I installed sbackup on Mint LMDE from source and the installation went fine with all dependencies are met.
When I run it it terminates with this output.
Can someone help me to solve this?
I am using sbackup 0.11.3 on debian testing 32 bit released as Mint LMDE with Gnome Desktop 2.30

Hourly backups run fine now. No notification icon like in Ubuntu but the backups look ok.

[Jean-Peer Lorenz (peer.loz)]

Thank you for using SBackup and for taking the time reporting this bug. I'll have a look into it though I need to install Mint firstly. So, it could take a while. Please report any progress on this issue.

[BlueLight (bluelight-auroville)]

No notification icon like in Ubuntu is working with all infos.

[BlueLight (bluelight-auroville)]

The notification icon like in Ubuntu is working with all infos.

[Jean-Peer Lorenz (peer.loz)]

So, the indicator application (notification icon) is being started and everything works as expected under Mint LMDE? If so, we can mark this bug as invalid.

[BlueLight (bluelight-auroville)]

Too early :-)

The scheduled hourly backup works but without notification icon. I saw it only once.
The scheduled daily backup for whatever reason doesn't start also there is a clear entry in /etc/cron.daily
sbackup -> /usr/local/share/sbackup/sbackup-launch

Also the email notification does not work but this is a different bug. Do you want me to post these in different locations?

[BlueLight (bluelight-auroville)]

The timed backups with crom like 0 4 * * * work but without notification icon and no emails sent

[BlueLight (bluelight-auroville)]

log file sbackup

[Jean-Peer Lorenz (peer.loz)]

Could someone launch a backup using commandline option '--legacy-indicator' (see https://answers.launchpad.net/sbackup/+faq/1294):

$ sbackup --legacy-indicator

and post the outcome here? Thanks.

[master-sonic (master-sonic-web)]

I managed to get the indicator icon working. However, the workaround is pretty dirty. sbackup is checking whether gnome is running by checking if there is a process called 'gnome-session'. For debian, this does not seem to be the case. Now I just made sbackup check for gnome-panel instead of gnome-session. I know this is pretty dirty but it's a quick fix until a real solution comes around

[Jean-Peer Lorenz (peer.loz)]

I did some preliminary tests and still have some questions:

* What desktop environment are you running? Gnome? Gnome-Shell?
* Could you open a terminal and run 'ps aux | grep -i gnome' and post the output here?

Thanks for your help.

[Jean-Peer Lorenz (peer.loz)]

Thanks for your response. The problem is caused by a test against 'gnome-session' which is not present in certain configurations. Here 'gnome-session' is replaced by 'x-session-manager'. I'll add a workaround to the 0.11 series.

[rogerw05465 (rogerw-nordlink)]

Not sure what to do now. I see on the bug report that there is a solution to the bug, but I can't find my way to it yet.

Ubuntu 12.04
xfce windows manager.
sbackup was working fine from 10.x through 11.10. The upgrade from Live CD seems to have killed it.

I am Using now 12.04 32 bit with sbackup 0.11.4-0ubuntu4 and all works well.

:)

[BlueLight (bluelight-auroville)]

We are not using Mint LMDE any more. This distro is too buggy and not enough support and since Canonical decided 5 years updates on the LTS we are back to Ubuntu.

[C Cheng (ckcheng)]

I had the same problem with sbackup 0.11.4 on Lubuntu, installed as Ubuntu 12.10 with lubuntu-core package installed. Scheduled backups work though. I tried instead:

    sudo /usr/share/sbackup/sbackup-launch

and that seems to work. I checked and I don't have 'gnome-session' or 'x-session-manager' running. Instead, I have 'lxsession'.

[be4truth (short-unique-name-in-use)]

while sbackup 0.11.4 on 64bit ubuntu 14.04 was running nicely with indication the upgrade to 16.04 disabled the indicator with 0.11.6

[be4truth (short-unique-name-in-use)]

Here what the terminal says during launch:

[Anton (feenstra)]

I can get the indicator icon when I manually start /usr/share/sbackup/sbackup-indicator, it also shows the backup progress accurately. The terminal says the same as be4truth reports above, however when I manually do:
$ pgrep gnome-session
2724

So, apparently something is not parsed back correctly? I'll try to do some additional searching and testing in the coming days.

If I try to start the indicator manually I get this:

** (sbackup-indicator:5429): WARNING **: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
