Problem with RealVnc on Raspberry pi - mcgarrydware - 2024-06-08
I have setup a raspberry pi with a Hat to receive AIS signals and also have connected a GPS receiver via USB. All that works fine and I can connect to it with my Android tablet using Navionics app. I can also SSH into it from my raspberry 400 that I use as the main computer on the boat. RealVnc used to work fine until I decided that I didn't like the resolution it was set at. As soon as I tried to change it I messed it up. Now all I get is the top left hand corner of what should be the desktop of my raspberry pi. I have tried endlessly to change it back but to no avail. Any help would be much appreciated.

Can you still see the full-sized desktop via a monitor is it not setup that way?

It's not setup with a monitor. The raspberry pi is kinda buried at the back of a locker with all the cables fed in to it. I suppose I could pull it out
and attach it to a monitor but I was hoping there would be a way to reset the realvnc via the ssh.
Thanks for reply.

You should be able to do that, can you see the start menu at all?
If not try sudo raspi-config from a terminal and then I think it's advanced options. I can't remember on the pi if the command line and the gui are two different settings- worth a try anyway

Cheers for the reply. Unfortunately I am at home at the moment. will go down to the boat tomorrow and try your suggestion.
Will let you know how I get on.

Ok I got to the boat today. I couldn't try to connect to a monitor as I had forgotten that the raspberry pi 3b I was using
uses a full sized hdmi connector and on the boat I only had the micro one that the raspberry pi 400 uses.
However I did also try the raspi-config and when I rebooted it was working fine. Only problem is I changed a few
settings. Not sure which one did it. I enabled some compositor and reduced the res setting to the lowest.
will have to mess around someday to figure out which one it was. So happy its working again.

I think you need a dummy HDMI to charge to higher resolution

I wondered about that as it's the headless version of openplotter that is on my raspberry pi.
I thought it would not connect to a monitor, never checked before. Probably wrong..
I assumed it was a virtual desktop it was
sending out to the client computer.
When I figure out the reason it's working now I will let you know..
