Installation and Setup Guide

If you are using a Ubuntu 10.4 Linux client system and you want to display the client user interface in a
language other than English, you must set the client system to use a locale that uses UTF-8 encoding.
Keyboards and Monitors
You can use multiple monitors and all types of keyboards with a remote desktop. Certain settings ensure
the best possible user experience.
Best Practices for Using Multiple Monitors
Following are recommendations for successfully using multiple monitors with a remote desktop:
n
Define the primary monitor as the bottom-left-most monitor.
n
Enable Xinerama. If you do not enable Xinerama, the primary display might be identified incorrectly.
n
The menu bar will appear on the top-left-most monitor. For example, if you have two monitors side by
side and the top of the left monitor is lower than the top of the right monitor, the menu bar will appear
on the right monitor because the right monitor is still the top-left-most monitor.
n
You can use up to 4 monitors if you have enough video RAM.
To use more than 2 monitors to display your remote desktop on a Ubuntu client system, you must
configure the kernel.shmmax setting correctly. Use the following formula:
max horizontal resolution X max vertical resolution X max number of monitors X 4
For example, manually setting kernel.shmmax to 65536000 allows you to use four monitors with a
screen resolution of 2560x1600.
n
Horizon Client uses the monitor configuration that is in use when Horizon Client starts. If you change
a monitor from landscape to portrait mode or if you plug an additional monitor in to the client system
while Horizon Client is running, you must restart Horizon Client in order to use the new monitor
configuration.
Horizon Client supports the following monitor configurations:
n
If you use 2 monitors, the monitors are not required to be in the same mode. For example, if you are
using a laptop connected to an external monitor, the external monitor can be in portrait mode or
landscape mode.
n
If you have a version of Horizon Client that is earlier than 4.0, and you use more than 2 monitors, the
monitors must be in the same mode and have the same screen resolution. That is, if you use 3
monitors, all 3 monitors must be in either portrait mode or landscape mode and must use the same
screen resolution.
n
Monitors can be placed side by side, stacked 2 by 2, or vertically stacked only if you are using 2
monitors.
