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.
