Compiz and VNC dont get together well

Xi0N · 2010-06-18 10:17:57

My machine runs a vnc server permanently, the default one that comes with gnome (i think its called vino)
If i have compiz effects enabled, i cannot see anything of my desktop: I just see the background image - no windows, no gnome bars, nothing....
Anyone else experiences the same issue?

Thanks!

i use x11vnc and enable the option "-noxdamage", you may want to try.

x11vnc -noxdamage -display :0.0  -forever -rfbauth $HOME/.vnc/passwd -o /var/log/vnc.0.log

Would you elaborate a bit more, please?

Thanks!

vnc server tries by default to just paint areas of the screen which are modified, to save bandwidth, thanks to Xorg server damage extension.
When using a composite manager like compiz this doesn't work, so you have to explicitely tell your server to disable that tweak, sorry.

from x11vnc man page:

       -noxdamage

              Do not use the X DAMAGE extension to detect framebuffer changes even if it is available.  Use -xdamage if your default is to have it off.

              x11vnc's use of the DAMAGE extension: 1) significantly reduces the load when the screen is not changing much, and 2) detects changed areas (small ones by default) more quickly.

Ok, i see.... in gnome, by default, you have vino-server... im trying to look for an equivvalent for the noxdamage option of x11vnc for applying it to the current vino-server

If i figure anything out, ill let you know...

btw.... would it be difficult to enable vnc from the gdm screen?

Sort of like in windows.... in which vnc runs as a service and you can access the machine remotely already from the login screen.... (im concerned about the security issues this might come with, and i think i can live with them)

Is explained well here:
http://wiki.archlinux.org/index.php/X11vnc
But it requires you to run x11vnc as root, maybe you better check if there is a way to configure vino to not use xdamage first.
