     Hello,
     
        Anybody can help me on the following problem;
     
        I have compiled (using gcc 2.95.3) the VNC source under Solaris 
     2.7, I have tried on Solaris 2.7 (On Solaris 2.5.1 we do not have the
     javac..). I have some question that need your advice;
     
     1. Everytime when I connected the vnc server with the vncviewer, I 
     have some message which is related to the color;
     
     "VNC authentication succeeded
     Desktop name "root's X desktop (Logos:1)"
     Connected to VNC server, using protocol version 3.3 VNC server default 
     format:
     8 bits per pixel.
     True colour: max red 7 green 7 blue 3, shift red 0 green 3 blue 6
     Using default colormap and translating from BGR233.  Pixel format:
     8 bits per pixel.
     True colour: max red 7 green 7 blue 3, shift red 0 green 3 blue 6
     Got 199 exact BGR233 colours out of 256 Using 6 existing shared 
     colours"
     
     
     I have tried to modify the vncserver ( on the $depth = 8; to 16 or 32, 
     )
     but I remain connected with 8 bits color, the message as following;
     
     --------------------------------------------

     format:

     Most significant byte first in each pixel.

     I have also changed the .vnc/xstartup's windows manager from twm
     (openwin) to dtwm (CDE) but I do not see any improvemnet, eventhougt I 
     have connected via netscape browser (Just for your information both 
     server and client are Solaris 7 installed with Creater 3D graphics 
     card) Do you have any idea ? I have read the FAQ but nothing on this 
     topic.
     
     
     2. Anyway to improve the speed of displaying the windows ?
     
     
     Thanks,
