Description

The popular novnc (https://github.com/novnc/noVNC) client switches to a different pixel format after connection in order to reduce load on the client which is running in a browser.
The bhyve VNC server ignores this and just continues to use its default format, resulting in colours being shifted (quite a pleasing affect - see below - but not what people generally want)

Updated by Andy Fiddaman 4 months ago

This change has been in OmniOS bloody for two months now, being exercised with a variety of VMs and VNC clients. I have personally tested the following clients
(the protocol version is shown, along with whether the client opted for raw or zlib compression and whether it supported extended keyboard events). I predominantly tested these with a Windows VM.

  • TightVNC RFB 003.008 raw
  • UltraVNC RFB 003.008 zlib
  • TigerVNC RFB 003.008 raw QEMU ext kevent
  • noVNC RFB 003.008 raw RGBx pixmap QEMU ext kevent
  • noVNC 1.2 RFB 003.008 raw QEMU ext kevent
  • Macos SS RFB 003.003 zlib
  • Android VNCViewer RFB 003.008 zlib

Mike Zeller has also tested this as part of reviewing and said:

I built and tested these bits by booting into a gate onu. I confirmed that I am able to connect to VNC with/without a password and that the wait feature works. Also confirmed that I was able to connect from the MacOS "Screen Sharing" app.
