Mouse scaling
Some earlier versions of Linux did not support adjustable mouse accelerations. For installations
that must support these earlier versions, you can choose among three preconfigured mouse scaling
options or set your own custom scaling. The preconfigured settings are Default (1:1), High (2:1) or
Low (1:2):
• In a 1:1 scaling ratio, every mouse movement on the desktop window sends an equivalent
mouse movement to the server.
• In a 2:1 scaling ratio, the same mouse movement sends a 2X mouse movement.
• In a 1:2 scaling ratio, the value is 1/2X.
To set mouse scaling:
1. Select Tools - Session Options from the Video Viewer window menu.

Click the Session Options button.
The Session Options dialog box appears.

To set custom scaling:
a. Click the Custom radio button to enable the X and Y fields.
b. Type a scaling value in the X and Y fields. For every mouse input, the mouse movements
are multiplied by the respective X and Y scaling factors. Valid input range is 0.25-3.00.
Vendor-specific video settings
Video settings vary significantly among manufacturers. Avocent maintains an online database of
optimized video settings for various video cards, particularly Sun-specific ones. This information
can be obtained from Avocent’s online knowledge base or by calling Avocent technical support.
Mouse alignment and synchronization
Because the DSR switch on-board web interface cannot get constant feedback from the mouse,
there are times when the mouse on the DSR switch may lose sync with the mouse on the host
system. If your mouse or keyboard no longer responds properly, you can align the mouse to
re-establish proper tracking.
