VNC not working after upgrade to etch.

[Colin Alie <calie@uwaterloo.ca>]

Hello,

After upgrading to Etch, I'm having problems remotely accessing the native X server (i.e., display :0) using VNC.  I can successfully connect to the VNC server (connection initiated with vncviewer 4.0 from Sarge (package xvnc4viewer)) but I have the following problems:

1. screen elements take a very long time to redraw (maybe 20s between the time the window border appears and the contents _begin_ to appear)
2. window elements don't appear where they should (e.g., text will appear outside of the terminal window).  The corrupted display occurs on both sides of the connection.

The first problem is more pronounced the larger the desktop.  At 1280x1024, the system is so unresponsive as to be completely unusable.  If I restart the X server at 800x600, the responsiveness is fine but the drawing problems still exist.

I have no problems with a standalone VNC server; I only have problems when connecting to the native X server with the VNC module loaded and these problems began after the upgrade to Etch.  Does anybody have any ideas?

Until next time, Colin.

P.S.  Below is representative of the xorg.conf I've been using.
