How to Install

2. 2. Refresh the Package List

   As root, sync your mirror and update package indices:

   slackpkg update gpg

   slackpkg update

3. 3. Install or Upgrade MESA

   Install (or upgrade) the core MESA package and utilities:

   slackpkg install mesa

   Optionally add demos and Vulkan tools (if available):

   slackpkg install mesa-demos

   slackpkg install vulkan-tools

4. 4. Verify Installation

   Run the OpenGL test:

   glxinfo | grep "OpenGL version"

   Run the Vulkan test (if vulkan-tools is installed):

   vulkaninfo | grep "apiVersion"

5. 5. Reboot (if needed)

   If your X server or Wayland session doesn’t pick up the new drivers automatically, reboot:

   reboot

That’s it! You now have the latest MESA drivers running on your Slackware system.
