Right click on windows desktop, choose settings->background, then under wallpaper select (None). That disables windows wallpaper. Maybe there's something else. Hope it helps. -----Original Message----- From: Brad Noyes [mailto:maitre@ccs.neu.edu] Sent: Monday, December 03, 2001 2:36 PM To: wlug@mail.wlug.org Subject: [Wlug] VNC performance Hi All, I remember some time ago talking with Andy, and others about VNC performance at a wlug meeting. I remember that setting the depth 8 will help performance, as well as disabling the wallpaper. I am running the server on windows, and the client on a linux machine. VNC's site has info for disabling wallpaper, but it seems to involve editing a registry file. When i try to do so, i get an access denied message, because that file is read only. Can someone help me out here? I really know very little about windows. On the client side, the option '-depth 8' doesn't seem to do very much i get '16 bits per pixel'. If anyone knows of any other methods for speeding up VNC, please post.

HI Brad et al, Definitely get that wallpaper (background) to be some plain, boring, solid color, or it will adversely effect VNC performance unless you have really good network bandwidth. Background gradients really kill the performance in many cases. Once that's done, make sure the server and viewer are speaking the same number of colors. I believe the server defaults to 8 bit color. If the server is run with 24 bit color (for example) and the viewer is only 8 bit color, VNC has to transpose and that can reduce performance. Also, try using a Java enabled browser as a VNC client. Sometimes, it works better than the native vncviewer, but only for 8 bit color situations. This is heavily dependent on the Java implementation. Finally, check the network and make sure you aren't bandwidth limited. I'vve seen VNC takes 500 kb/sec on my cable modem during "compilcated" screen redraws, but then settle back down during more idle periods. If you are bandwidth limited, you might try www.tightvnc.com. I hope this helps. Let us know your results. Andy On Monday 03 December 2001 02:51 pm, dibb_jim@emc.com wrote:
