Overview

The Terra Mesa subrepo provides a patched and updated version of Mesa, the open-source graphics library that powers graphics on Linux systems. This version may include newer features, performance improvements, and hardware support that might cause conflicts with Fedora’s standard Mesa packages.
Installing Mesa from this repository will replace Fedora’s default Mesa packages. This affects all graphics operations on your system.

​
What is Mesa?

Mesa is a comprehensive graphics library that implements:
  • OpenGL - Cross-platform 3D graphics API
  • Vulkan - Modern high-performance graphics API
  • OpenCL - Heterogeneous parallel programming
  • VA-API - Video acceleration API

​

Priority 80 ensures Mesa packages from this repository take precedence over Fedora’s default Mesa.

​
Installation

1

Enable the repository

Install the Terra Mesa release package:
sudo dnf install terra-release-mesa
2

Update Mesa packages

Update to Terra’s Mesa packages:
sudo dnf distro-sync mesa\*
The distro-sync command ensures all Mesa packages are switched to the Terra repository versions.
3

Reboot your system

Reboot to ensure the new graphics stack is fully loaded:
sudo reboot
4

Verify installation

Check your Mesa version:
glxinfo | grep "OpenGL version"
For Vulkan:
vulkaninfo | grep "driverVersion"

​
Features and Optimizations

​
Performance

LTO (Link-Time Optimization) is disabled for Mesa to maintain compatibility with certain games and applications. See Red Hat Bugzilla #1862771 for details.

​
Additional Libraries

The build includes support for:
  • libunwind - Better stack unwinding for debugging
  • lm_sensors - GPU temperature monitoring
  • Valgrind - Memory debugging support (on supported architectures)

​
Supported Architectures

Terra Mesa is built for:
  • x86_64 - 64-bit Intel/AMD
  • aarch64 - 64-bit ARM
  • i386 - 32-bit Intel/AMD (for multilib support)

​
OpenCL Support

For AMD GPUs, OpenCL support is included by default. This enables GPU computing for:
  • Video editing and encoding
  • 3D rendering
  • Machine learning workloads
  • Scientific computing

​
Troubleshooting

​
Graphics issues after installation

If you experience graphics problems:
  1. Check driver status: 
    dmesg | grep -i "drm\|gpu\|graphics"
  2. Verify Mesa version: 
    rpm -qa | grep mesa
  3. Test OpenGL: 
    glxinfo -B

​
Reverting to Fedora Mesa

To switch back to Fedora’s Mesa: 
sudo dnf config-manager --set-disabled terra-mesa
sudo dnf distro-sync mesa\*
sudo reboot

​
Gaming Performance

For gaming, Terra Mesa provides:
  • Latest Vulkan API support
  • ACO shader compiler for AMD GPUs
  • Optimized drivers for recent games
  • Better compatibility with Proton/Wine

​
Source Code

Mesa source packages are available: 
sudo dnf config-manager --set-enabled terra-mesa-source
dnf download --source mesa
