If a Linux virtual machine's Number of displays value is less than the actual required count, one or more
monitors display blank for the desktop.
If you encounter an autot issue with the recommended seings, you can specify a larger vRAM size.
vSphere Client permits a maximum vRAM size of 128 MB. If your specied size exceeds 128 MB, you must
modify the vmx conguration le manually. The following example species a vRAM size of 256 MB:
svga.vramSize = "268435456"
Configuration Parameters
To display the Linux remote desktop on multiple monitors, you must set certain conguration parameters
for the virtual machine. The general steps to set a conguration parameter for a virtual machine are as
follows:
1 Power o the virtual machine.
2 In the vSphere Web Client, right-click the virtual machine and select Edit .
3 Click the VM Options tab and click Advanced.
4 Click Edit and then Add Row.
5 Enter the conguration parameter name and value.
6 Click OK to save the changes.
You must set the following conguration 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 conguration 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.
Screen Size Limitation of 4096x4096 Monitors
For RHEL 6.8/6.9/7.3, CentOS 6.8/6.9/7.3, Ubuntu 16.04, SLED 12 SP2, and SLES 12 SP2, the maximum screen
size for 2D and vSGA is 4096x4096. When you run the xrandr command, the rst line of the output has
maximum 4096x4096.
For Ubuntu 14.04, the limitation is also introduced if you install the latest patches from the ocial Ubuntu
repositories.
