The same is true of other KMS drivers (intel, nouveau, etc.). If the drm is not loaded, the ddx assumes UMS and tries to load the drm. If it loads in KMS mode, you don't want two drivers handling the same hw, so the ddx bails to prevent that. If you try and load the drm from X and assume that the kernel is in KMS mode, you break old systems with old kernels that don't support KMS. The other problem with having the ddx load the drm for KMS mode is that with KMS, the drm handles all of the chip init. With UMS when you load the drm in UMS mode, the kernel module doesn't do anything at load time; it just waits until userspace inits the hw and actually decides to use the drm. With KMS, we have no way of knowing when the KMS drm has finished loading or initializing the hw so we may end up trying to use the KMS drm before it's properly loaded. It's not a configuration we want to support. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/534662 Title: [RV635] No hardware acceleration on ATI Radeon 3650 HD using 'radeon' driver To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/534662/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 534662]
As of 6.14.3 the ddx will stop loading if the ddx is in UMS mode and the drm is in KMS mode to prevent display problems. UMS is no longer supported in the DDX on Linux. Support for UMS was removed in xf86 -video-ati git last month. UMS only supported chips up through evergreen and the open source 3D drivers dropped UMS support a while ago. The open source radeon driver and fglrx are completely different driver stacks and require some system adjustments to switch between then (different kernel modules, different ddx, different 3D drivers, different libgl and libglx, etc.). It's probably easiest to have a script to switch the environments between the two drivers or something like that. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/534662 Title: [RV635] No hardware acceleration on ATI Radeon 3650 HD using 'radeon' driver To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/534662/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Both fglrx and radeon support dynamic power management so this does not likely have anything to do with power management. It looks like a plain old GPU hang.
