If I understand correctly, my computer (2011 27 inch iMac) has an integrated intel GPU, but Fedora is using the Radeon GPU. Is there any way what GPU you use? I did not find any documentation regarding this, but maybe I looked at the wrong places?
With Thinkpad T400 (ATI/Intel dual graphics) I could theoretically (it's broken on my machine) switch the GPU in BIOS. There is almost certainly nothing in Linux drivers to do so.
I can switch GPUs in my T510 with switcheroo, which is included in Fedora already.
See: http://en.gentoo-wiki.com/wiki/Vga_switcheroo and http://christof.damian.net/2010/11/fedora-14-on-lenovo-thinkpad-t510.html?sh...
Not sure if this applies to the iMac
