Why I am getting error "libGL error: failed to load driver: radeon" when trying to run "glxinfo" ?

Issue

• Unable to run glx applications on local system console.
• Graphical interface is very slow on RHEL7 console.
• When executing glxinfo on local system console, it's showing that libGL is unable to initialize radeon_dri drivers and switching back to software rendering with below messages:

libGL error: failed to create dri screen
