Kevin, Our experience here with x86_64 Fedora 10 linux and the radeon drivers on a couple machines with Radeon X1650 Pro cards has been very uneven. One of the boxes is very fragile to spontaneous reboots when running the free drivers and using UCSF Chimera to work with MD trajectories. The other box still has a habit of blanking the screen for minutes at time despite having the nomodeset flag passed to the kernel. I am afraid things will only get worse under Fedora 11. So far, testing on a MacBook Pro with X1600 graphics, I find that pymol still renders outside of its windows. While I appreciate the aims of these changes to X11 and the free drivers, the problem is that Fedora has become destablized. It is really exposing the limitations of a monolithic kernel when the graphics drivers keep taking down the entire box. Jack ps We run a large amount of OpenGL software (free and commercial) and have found the non-free drivers to be more compatible in general. Hopefully this will improve over time. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
