Non-vGPU graphics cards

Non-vGPU graphics cards refer to graphics cards that don’t support the NVIDIA virtual GPU (vGPU) solution. This article provides information on using non-vGPU graphics cards.

Prerequisites

To use non-vGPU graphics cards, you must:

• Install XDamage as a prerequisite. Typically, XDamage exists as an extension of XServer.
• Set CTX_XDL_HDX_3D_PRO to Y when installing the Linux VDA. For information about environment variables, see Step 7: Set up the runtime environment to complete the installation.  

Configuration

Modify Xorg configuration files

For NVIDIA graphics cards

If you are using an NVIDIA driver, the configuration files are installed and set automatically.

For other graphics cards

You must modify the four template configuration files installed under /etc/X11/:

• ctx-driver_name-1.conf
• ctx-driver_name-2.conf
• ctx-driver_name-3.conf
• ctx-driver_name-4.conf

Using ctx-driver_name-1.conf as an example, do the following to modify the template configuration files:

1. Replace driver_name with your actual driver name.

   For example, if your driver name is intel, you can change the configuration file name to ctx-intel-1.conf.

2. Add the video driver information.

   Each template configuration file contains a section named “Device,” which is commented out. This section describes the video driver information. Enable this section before adding your video driver information. To enable this section:

   1. See the guide provided by the card manufacturer for configuration information. A native configuration file can be generated. Verify that your card can work in a local environment with the native configuration file when you are not running a Linux VDA session.

   2. Copy the “Device” section of the native configuration file to ctx-driver_name-1.conf.

3. Run the following command to set the registry key so that the Linux VDA can recognize the configuration file name set in Step 1.

   /opt/Citrix/VDA/bin/ctxreg create -k "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Citrix\XDamage" -t "REG_SZ" -v "DriverName" -d "intel" --force
