VirtualGL: Setting Different Devices (AMD CPU with No Integrated Graphics) for Hardware Acceleration over VNC Connection
VirtualGL is an open-source tool that enables 3D acceleration on a remote desktop, allowing you to run GPU-accelerated applications over VNC. This article will guide you through the process of setting up VirtualGL with an AMD CPU that does not have integrated graphics for hardware acceleration over a VNC connection.
Prerequisites
- An AMD CPU without integrated graphics
- A dedicated GPU compatible with VirtualGL
- A VNC server, such as TigerVNC or TurboVNC
- VirtualGL and TurboVNC packages
Installation
To install VirtualGL and TurboVNC, use the following commands:
# For Ubuntu/Debian:
sudo apt-get update
sudo apt-get install virtualgl turboVNC
# For CentOS/RHEL:
sudo yum install virtualgl tigervnc-server
Configuration
Configure the VNC server to use VirtualGL for hardware acceleration:
# Create a script for the VNC server:
nano ~/.vnc/xstartup
# Add the following lines to the script:
#!/bin/bash
export LIBGL_ALWAYS_INDIRECT=1
vglrun turboVNCServer
# Make the script executable:
chmod +x ~/.vnc/xstartup
Running Applications
To run an application with hardware acceleration, use the following command:
vglrun application_name
Testing
Test the setup by connecting to the VNC server and running a GPU-accelerated application. If successful, you should see the application's 3D graphics rendered smoothly.
In this article, we have discussed how to set up VirtualGL for hardware acceleration on an AMD CPU without integrated graphics. By following the steps outlined above, you can successfully run GPU-accelerated applications over a VNC connection.
