I am playing around with making a "desktop" workstation out of a Raspberry PI3 using the armv7hl CentOS. 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).
