X11vnc on FreeBSD10.4-p3 doesn't work on GA-N3050-d3h.

Hi all

I am Yoshi.

I have troubles with x11vnc on FreeBSD10.4-p3.

First, “startx” failed and said that it could not find video driver  when I installed FreeBSD10.4-p3 and Mate to GA-N3050N-D3H.

That is why I wrote to use scfb driver in /usr/local/etc/xorg.conf/driver-scfb.conf.

It worked well but not so fast but enough for me.

Second,  I added  x11vnc and started it as below:

 root at mysql:/usr/home/ccmail # cat vnc.sh
#!/usr/local/bin/bash
x11vnc -rfbauth ~/.vnc/passwd -forever -display :0 &

root at mysql:/usr/home/ccmail # 

But, it doesn’t work as below. Could anyone let me know the reason of my trouble?

$ ./vnc.sh

08/02/2018 13:35:14 
08/02/2018 13:35:14   Most compositing window managers like 'compiz' or 'beryl'
08/02/2018 13:35:14   cause X DAMAGE to fail, and so you may not see any screen
08/02/2018 13:35:14   updates via VNC.  Either disable 'compiz' (recommended) or
08/02/2018 13:35:14   supply the x11vnc '-noxdamage' command line option.

08/02/2018 13:35:14 Wireframing: -wireframe mode is in effect for window moves.
08/02/2018 13:35:14   If this yields undesired behavior (poor response, painting
08/02/2018 13:35:14   errors, etc) it may be disabled:
08/02/2018 13:35:14    - use '-nowf' to disable wireframing completely.
08/02/2018 13:35:14    - use '-nowcr' to disable the Copy Rectangle after the
08/02/2018 13:35:14      moved window is released in the new position.
08/02/2018 13:35:14   Also see the -help entry for tuning parameters.

08/02/2018 13:35:14   to: '-cursor most'.
08/02/2018 13:35:14   to disable this behavior use: '-cursor arrow'
08/02/2018 13:35:14   or '-noxfixes'.

08/02/2018 13:35:14 Scroll Detection: -scrollcopyrect mode is in effect to
08/02/2018 13:35:14   use RECORD extension to try to detect scrolling windows
08/02/2018 13:35:14   (induced by either user keystroke or mouse input).
08/02/2018 13:35:14   If this yields undesired behavior (poor response, painting
08/02/2018 13:35:14   errors, etc) it may be disabled via: '-noscr'
08/02/2018 13:35:14   Also see the -help entry for tuning parameters.
08/02/2018 13:35:14   You can press 3 Alt_L's (Left "Alt" key) in a row to 
08/02/2018 13:35:14   repaint the screen, also see the -fixscreen option for

08/02/2018 13:35:14   Automatically switching to -xkb mode.
08/02/2018 13:35:14   If this makes the key mapping worse you can
08/02/2018 13:35:14   disable it with the "-noxkb" option.

Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?

The scheme stores pixel data offscreen on the VNC viewer side for faster
retrieval.  It should work with any VNC viewer.  Try it by running:

    x11vnc -ncache 10 ...

One can also add -ncache_cr for smooth 'copyrect' window motion.
