Hello, I need your help with installing VNc. We were using it on Windows without any issues, but we encountered a problem when transitioning to Linux Ubuntu. I hope to receive your support in resolving this problem.

Try:

C#: 
sudo apt-get install -y libgdiplus

I've been running one of my p58 dev servers, including VNC on Ubuntu so hopefully that will fix it for you.

I have already tried installing the package(


install: 
sudo apt-get install -y libgdiplus
Reading package lists... Done

libgdiplus is already the newest version (6.0.5-0xamarin1+ubuntu2004b1).
0 upgraded, 0 newly installed, 0 to remove and 111 not upgraded.

Could the reason be the version of Mono?

mono: 
mono --version

Hmmm same mono version as me, so not sure why you're still having that issue.

Do something like this and see if for whatever reason you have multiple that may be causing conflicts. Double check it's in /usr/lib/ - if not you may need to do a symlink to wherever it got installed.
C#: 
sudo find / -name "libgdiplus.so"

All else failing try following the mono docs here. Hopefully, that helps because VNC definitely works on mono

If the unix wrapper hasn't added support for 16-bit image formats to gdi+ yet (it wasn't supported in mono afaik) then you can try changing the pixel format to 32-bit to avoid the error, but the UOFont may not work as intended (it will be obvious on things like MenuGump where it measures string widths to determine gump width).

I will work out an alternative as I did when writing the asset handlers for the ServUO core, if the data is read in its raw format, and converted to 32-bit, then loaded into the image, it will work.

I found two files that might cause a conflict. Should I delete the one located... /usr/local/lib/libgdiplus.so ?


libgdiplus.so:

I changed the value from 16 to 32 when starting the server and encountered one error. However, the server started successfully. But it seems that the system is not functioning properly for me, as the VNC command is not recognized.

I was mistaken, the server did not start.

In MONO libgdiplus, System.Drawing.Bitmap() does not impletemted.
the source code(mono/mcs/class/System.Drawing/System.Drawing/Bitmap.cs) said:
public sealed partial class Bitmap : System.Drawing.Image
{
....
public Bitmap(int width, int height, System.Drawing.Imaging.PixelFormat format) => throw new PlatformNotSupportedException();
....
}

For using MONO, UOFonts.cs needs more hard works. but i can not do it.
