While Linux 6.2 supports Arc Graphics out-of-the-box and Mesa 23.1 has good OpenGL/Vulkan support, for those running Linux distributions on older kernels and Mesa packages there is less than ideal support -- either no support at all or having to resort to force-enabling the DG2/Alchemist support and potentially running on older OpenGL/Vulkan drivers with various problems.
