VNC display won't update

[Percy Bottle]

Hi,

I just purchased this app for my iPod Touch 64. I'm VNCing to my
Ubuntu Karmic laptop. I've tried via SSH and Raw. I can see the Ubuntu
desktop perfectly in my iPod, but once displayed, the screen never
updates. I can double-tap on a menu, for example, but apparently
nothing happens. If I disconnect VNC and reconnect, then I see that
the menu has opened in response to my tap. But I have to disconnect/
reconnect to see any changes to the screen. Have I missed something?

SSH in a terminal works fine.

Thanks for any help.

In Ubuntu, are you running a a VNC server such as tightvnc ? IIRC, you need
to go into ~/.vnc/ and modify a file to set the environment you want as the
desktop. I believe the name of the file is xstartup or similar.

Once you have done that, you run vncserver and then you should be able to
login.

I found out what the problem was: the compiz 3d environment. Once I
turned that off, the screen updates worked perfectly (and quite
quickly).

Further to this, I've found that I can still use compiz if I make a
change to the configuration of my vnc server (I'm using the built-in
Ubuntu vnc server, called vino-server, that you get to via System/
Preference/Remote Server).

Run gconf-editor, then navigate to desktop/gnome/remote_access. Place
a check-mark in the disable_xdamage button. The description states
that this may slow vino down slightly, but I find performance on my
iPod is still good over the LAN.
