X is the width of the virtual session desktop.M is the amount of memory used for session graphics.To calculate how much memory is allocated to each HDX session, use the following formula: While this is not the total amount of memory used for the session, it is the easiest way of calculating per-session memory usage. It does not change for the life of the session. This is the memory allocated to each session for its graphics data when the session begins. For more information, see Knowledge Center articleĬTX230017 Understanding memory usage on the Linux VDA Knowing the virtual desktop size allows you to calculate the amount of memory used by each HDX session. Note: If a desktop displays at an improper resolution in a multi-monitor setup, adjust Dots Per Inch (DPI) settings on the Citrix Workspace app. Note that because the default configuration is 5120×1600 and 2 monitors, a configuration change is required to optimize memory usage for single-monitor deployments. In this example, the virtual desktop should be set to a size of 2560×1600. If all your users have only one monitor in the typical landscape layout, set the maximum virtual desktop size to the resolution of the monitor with the highest resolution. To accommodate all of the layouts above, you need to have a virtual session desktop of 5120×2560 because this is the smallest bounding rectangle that can contain all the desired layouts. For configurations with two 2560×1600 monitors, the possible layouts include: To accommodate the client monitor configuration in this example, the Linux VDA virtual desktop must be set to a size of 4160×2560.įor the greatest flexibility in a multi-monitor configuration, find the smallest bounding rectangle of all monitor layouts you want to support. The maximum height is too small to accommodate the virtual session desktop for this monitor layout. If each monitor in the above diagram has a resolution of 2560×1600, the out-of-the-box multi-monitor configuration parameters will be insufficient. Understanding memory usage on the Linux VDAĪllowing for different client monitor configurations Knowing the maximum virtual desktop size for your various client monitor configurations allows you to configure the Linux VDA to be flexible in terms of client monitor configurations.Ĭonsider the following client monitor configuration:.Allowing for different client monitor layouts.This is important for the following reasons: Similarly, the height of the virtual session desktop is the vertical distance, in pixels, from the origin to the bottom-left corner of the bounding rectangle of all monitors.

The width of the virtual session desktop is the horizontal distance, in pixels, from the origin to the top-right corner of the bounding rectangle of all monitors. That point is located at X = 0, Y = 0, where X and Y are the horizontal and vertical axes, respectively. Virtual session desktop size The origin of the virtual session desktop is calculated from the top-left corner of the bounding rectangle of all monitors.
