Keyboards and Monitors
You can use multiple monitors and all types of keyboards with a remote desktop. Certain seings 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
Dene the primary monitor as the boom-left-most monitor.
n
Enable Xinerama. If you do not enable Xinerama, the primary display might be identied 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
congure the kernel.shmmax seing correctly. Use the following formula:
max horizontal resolution X max vertical resolution X max number of monitors X 4
For example, manually seing kernel.shmmax to 65536000 allows you to use four monitors with a screen
resolution of 2560x1600.
n
Horizon Client uses the monitor conguration 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
conguration.
