Setting Up for Linux Desktops

Configuration Parameters
To display the Linux remote desktop on multiple monitors, you must set certain configuration parameters
for the virtual machine. The general steps to set a configuration parameter for a virtual machine are as
follows:
1 Power off the virtual machine.
2 In the vSphere Web Client, right-click the virtual machine and select Edit Settings.
3 Click the VM Options tab and click Advanced.
4 Click Edit Configuration and then Add Row.
5 Enter the configuration parameter name and value.
6 Click OK to save the changes.
You must set the following configuration parameters:
n
Set svga.autodetect to false.
svga.autodetect="false"
n
Calculate the svga.maxWidth and svga.maxHeight values according to the number and orientation
(horizontal or vertical) of the display monitors. The general rule is that the svga.maxWidth and
svga.maxHeight values must be large enough to support all the displays. For example, to support
four displays at the maximum resolution of 2560x1600, you must set the following values:
svga.maxHeight="3200"
svga.maxWidth="10240"
If you have multiple monitors, you must set these configuration parameters. Otherwise, you might
encounter one or more of the following problems:
n
The desktop is displayed on some of the monitors and the other monitors are blank.
n
A keystroke is displayed multiple times.
n
The desktop becomes slow.
n
The desktop is displayed in a small area of the screen.

SP2/SP3, the maximum screen size for 2D and vSGA is 4096x4096. When you run the xrandr
