[FreeNX-kNX] Minimum bandwidth req's

Fri Feb 23 14:28:16 UTC 2007

There's certainly some adjustment available on the client end.

In the 'Desktop' area of the 'General' tab of the configure options there's a 
slider for setting your connection type as Modem, ISDN, ADSL, WAN and LAN. 
This modifies the compression settings for the session to suit the bandwidth.

For a little more control you can change the image compression options by 
picking 'Use custom settings' from the 'Display' area of the 'General' tab. 
The 'Modify' button then lets you select PNG or JPEG and modify the level of 
compression used.
