Problem: Connecting to a vncserver (x11vnc) running on a machine that uses the intel drivers with onboard video using sna acceleration (default these days) causes a black screen to be displayed on the vncclient when xbmc is active. Disabling sna in /etc/X11/xorg.conf.d/20-intel.conf fixes the problem but causes poor video performance.

Note that I can connect to other machines that do not use the intel drivers (nvidia) and I get the expected results.

Example video hardware: Intel GMA X4500HD
Drivers packages in use: intel-dri libva-intel-driver xf86-video-intel
Linux distro and xbmc version: Arch Linux/XBMC v12.2
Also tested with git version 20130922.5aef1c5

Command used to start x11vnc on the target box:

Code:

/usr/bin/x11vnc -nap -wait 50 -passwd tEMp0raRY -display :0 -forever -o /var/log/x11vnc.log -bg

It does not matter if I use the -noxdamage switch; the result is the same.

Any suggestions are welcomed. Note that I did find this thread, but did not want to necrobump it.

Props to Chris Wilson; fixed upstream in commit: 63a81c (build xf86-video-intel from git if this is affecting you, at least until the changes gets packaged into an official release).

This bug is back with new hardware (Haswell + HD 4400). https://bugs.freedesktop.org/show_bug.cgi?id=72194

Looks like Chris fixed it upstream again.
