Maybe there is a better place to post this message but as my question 
was still CentOS related thought I would start here. Please advise if 
there is a better forum of which to ask this question.

I am playing around with making a "desktop" workstation out of a 
Raspberry PI3. I have had no problems installing the OS and pretty much 
have everything working except a Gnome desktop.

I did:

 > yum groupinstall "GNOME Desktop"

and from what I can tell everything necessary is installed. However when 
I try to start X up I see it try and start, the display blinks as if 
everything is good and then drops back down to the console. The log file 
shown below shows a single error ([  2665.952] (EE) AIGLX: reverting to 
software rendering).

Thanks for your help.
