I recently made the switch from fglrx to the radeon drivers for my video cards. The installation and modifications to the kernel went well and my system booted correctly. However, when I ran my compositor, compton, with backend glx things slowed down -- specifically, window dragging was very slow and laggy -- almost like a vsync issue. This led me to check my X.org log, where I found the following:

Any ideas as to how I can re-enable direct rendering and acceleration / resolve the problem with GLamor?

I recently made the switch from fglrx to the radeon drivers for my video cards. The installation and modifications to the kernel went well and my system booted correctly. However, when I ran my compositor, compton, with backend glx things slowed down -- specifically, window dragging was very slow and laggy -- almost like a vsync issue. This led me to check my X.org log, where I found the following:
