How to Install VMD (Visual Molecular Dynamics) on Ubuntu 24.04

March 08, 2026 2022 technical

VMD (Visual Molecular Dynamics) is a powerful tool for displaying, animating, and analyzing large biomolecular systems. While it’s a staple in computational biophysics, installing it on modern Linux distributions like Ubuntu 24.04 can sometimes be tricky due to dependency requirements.

In this guide, I’ll walk you through the process of installing VMD 1.9.4 Alpha, which is the recommended version for modern hardware.

1. Prerequisites: Install Dependencies

Before installing VMD, you need to ensure your system has the necessary libraries for OpenGL rendering and script execution.

Open your terminal and run the following command:

sudo apt-get update
sudo apt-get install -y libglu1-mesa libxinerama1 libxi6 libxrender1 libcanberra-gtk-module csh libtcl8.6 libtk8.6

2. Download the VMD Binary

VMD requires manual registration, so you’ll need to download it from the official website:

Go to the VMD Download Page.
Register or log in.
Under Version 1.9.4 LATEST ALPHA, select: LINUX_64 (RHEL 7+) OpenGL, CUDA, OptiX RTX, OSPRay
Save the file to your ~/Downloads folder.

3. Extract and Configure

Once the download is complete, navigate to your Downloads folder and extract the archive:

cd ~/Downloads
tar -xvzf vmd-1.9.4a57.bin.LINUXAMD64-CUDA102-OptiX650-OSPRay185.opengl.tar.gz
cd vmd-1.9.4a57

Now, run the configuration script:

./configure

4. Final Installation

After configuring, move into the src directory and install the binary to your system:

cd src
sudo make install

5. Verify the Installation

To start VMD, simply type:

vmd

You should see the VMD Main controller and a VMD Display window appear. If you have an Intel Iris Xe or similar integrated graphics, VMD will use OpenGL rendering for smooth performance.

Troubleshooting: Fix Tiny Fonts on High-DPI Screens

If you are using a high-resolution display, you might find that VMD’s menus and text are very small. VMD on Linux can be sensitive to scaling commands, so the most stable way to fix this is by setting the FLTK_SCALING_FACTOR environment variable before launching VMD.

You can create a simple launcher script (~/vmd_highdpi) to make this permanent:

#!/bin/bash
export FLTK_SCALING_FACTOR=2.0
vmd "$@"

Then use ~/vmd_highdpi instead of vmd to start the program with a larger main menu!

Happy simulating! 🧬💻
