Save toolbar and dashboard position?

[AndersG]

Hi!

I am playing with OpenCPN on a Raspberry Pi and slowly getting it the way I want, but one thing irritates me: The position and state of toolbar and dashboard is not saved when I restart. Ie I set it to vertical and to the right and dashboard active, but when I restart, it resets to horizontal and inactive.

What am I doing wrong?

My general Idea is to build a minimal unit with low power consumption to be used on a sailboat, using a Pi and a sunlight viewable 7" touchscreen. Target power consumption below 6W.

AndersG...

I did a quick test of OpenCPN v 4.8.4 on rPI-2, Rasbian 9.1 (Stretch).

Saving of toolbar and dashboard config is OK for me on this setup. Orientation and location of toolbar and dashboard are persisted across program start/stop.

Can you give more information?

Thanks
Dave

I trust you are aware of the openplotter project (Home | Sailoog) to get ocpn on the raspy.
All settings etc get remembered - have used on rpi2 and rpi3B.
When installing ocpn on raspi manually you need to set the file properties to allow updating - maybe this is the issue at your installation.

Openplotter is not required. OpenCPN saves the position and configuration of the toolbar as well as the dashboard in ~/.opencpn/opencpn.conf. It is possible that this file gets corrupted if you shut down the RPi by just removing power. But in my experience even that does not cause any problems with the configuration file.

When you start OpenCPN do you see any message box pop up on the screen?

[AndersG]

This is openplotter and I updated to the latest version and I always shut down from the menu. Is there anything special I need to do to save the settings?

No, the settings are saved whenever you change something.

[bdbcat]

Anders....

Are other things being saved correctly, such as boat position, connection parameters, chart groups, etc?

Dave

[AndersG]

Yes. Port settings and such are saved all right.

[transmitterdan]

This sounds like it might be an issue with the auto detect screen size.

Anders....

Please try this:
1. Start OCPN. Set the toolbar as you would like it. No dashboard visible yet.
2. Grab a screenshot.
3. Exit OCPN cleanly.
4. Post the config (~/.opencpn/opencpn.conf) file here, as well as the screenshot.

Thanks
Dave

I think you nailed it! When you say "Exit OCPN cleanly" I assume that I close the opencpn window as there seems to be no other menu item for that. When I do that and restart, the settings seems to be saved. If I shutdown the Pi through the menu, it is not. So apparently is the Pi shutdown not caught by OpenCPN.

This is not a life-and-death issue for me, especially as I now know how it works, but having an OS exit caught, especially if you add hardware to signal power good and a small backup for orderly shutdown, would be nice.

I don't use OpenPlotter so can you explain better what menu item you use to shut down? Is this an OpenPlotter menu or is it something in the operating system itself?

It sounds as if the shutdown you have been using is sending the wrong kind of kill signal to OpenCPN.

[AndersG]

Hit the raspberry top left corner, select shutdown. I just assumed that raspbian would send a signal to all running apps when I did that.

Pretty sure as far as the running programs are concerned it's like pulling the power plug, I use a little node-red to close down opencpn then shut down the Pi.

[AndersG]

OK. FWIW, Raspbian should send a SIGTERM to all running processes when you select poweroff.

Can you elaborate on your node-red?
