Open CPN, what's wrong here?

Check your chartsymbols.xml: Vector Palette

Looks like you might've messed that up, or copied in settings from somewhere. If in doubt, just delete all the preferences and start over with sane settings.

Interesting suggestion.

Okay I am a novice Linux user. That s57data folder is only owner (root) read and write, so I can't modify anything there. How would I do that?

EDIT solved that, open the file manager as super user.

So I tried downloading one of those chartsymbols.xml files. Yes it changed some of the colours, but it was still not right. It is still stuck in 2 colour mode, despite it saying it's in 4 colour mode.

Okay I am a novice Linux user.

Apologies if you know all of what follows. Is your system completely up-to-date? If you haven't done it recently, I suggest a

sudo apt-get update

followed by a

sudo apt-get dist-upgrade

and then

sudo apt-get install --fix-missing

just in case OpenCPN wants something which still isn't there. If that still doesn't work

sudo apt-get install --reinstall opencpn

or maybe

sudo apt-get purge opencpn
sudo apt-get install opencpn


to nuke all configuration and setting files as well.

Might be a system problem instead of an OpenCPN problem then. Check your display settings, perhaps you're running in a weird colour depth mode (bpp).

None of the above reset options made any difference.

I can't find any display settings that relate to colour depth, but the display does seem okay at displaying photographs and streaming live tv so I can't see there is anything wrong with it.

I also tried plugging the hdmi port on the computer into the television to see if I got a different result with (in effect) a different display adaptor. But that made no difference either.

Yep tried that, made no difference.
Have you tried having your computer exorcised?

On a more serious note, my next move would be to boot from a live CD/DVD/USB stick and try OpenCPN under that to eliminate the possibility that it's something in the Linux install.

Sorry for following up on an old thread. I seem to have the same problem with only 2 colors. I'd like to have everything deeper than 5 meters in white, but depth shading is using just light blue or grey. I have the same thing with both Linux and Android. Could the Finnish charts be in that way, hardcoded 10 m blue areas like the paper charts?

What format are "the finnish charts" in? If they're just raster data, you get whatever is on the picture. If they're vector data, OpenCPN wil do its thing, but of course only if there is a depth contour for 5m and not just 10.
