[GitHub] [incubator-nuttx] patacongo opened a new issue #1368: graphics/vnc/server breakage

patacongo opened a new issue #1368:
URL: https://github.com/apache/incubator-nuttx/issues/1368


   When the VNC server was created initially, it worked well.  However, in 2019 as part of the Twm4Nx development, I tried to use it and it did not work.  These are problems that I noted:
   
   * Mouse Input is not received and, hence, the cursor is not drawn.  Twn4Nx is not useful with not mouse cursor.
   * Background is black (it should be blue @16bpp).  Colors are bad.  Background is not transparent.  Toolbar buttons are visible but no other part of the Window.
   * I think that root cause of the drawing errors is the RRE is not working.  Or, more likely, it has been deprecated and no longer supported by the host VNC client.
   * There are other Twm4Nx/VNC server integration issues but these do not seem to be directly related to VNC server issues.
   
   I did make several changes in graphics/vnc/server but did not fix the basic problems.

   > @patacongo Is there a config that you were using for testing this?
   
   I tried to bring Twm4Nx (a Tom's Window Manager work-alike) using same70-xplained:twm4nx.
   
   Previously, I was using samv71-xult:vnc and samv71-xult:vnxwm successfully in the past.  But I suspected those are broken as well too.
   
   I did make several changes trying to bring up same70-xplained:twm4nx.  Since they were not successful they are suspect.
   
   Did you see the remote interface that Ken Pettit implemented using a extended pdcurses?  There are some screen shots here:

   That is a another nice way to get a remote (text) graphics interface.

   My gut feeling was that there is some issue with the message called RRE which paints a rectangular region with a run length encoded data.  I think that the RRE message was deprecated.. I am not sure.  That is the behavior that I saw; like the RRE was being ignored.
