Let me get this straight: With the Debian driver package installed, suspend/hibernation doesn't work no matter which kernel etc. you're using. With the Ubuntu driver package installed, both work. And these symptoms remain the same after switching back and forth between the versions of the driver package.

KMS should be enabled by default in both cases, so colour me skeptical. But you can try flipping it with the radeon kernel module parameter 'modeset' to see if it makes any difference in either case. Otherwise, apart from any possible code differences between the driver package versions (haven't checked yet), I assume that switching between them also requires switching versions of other packages, in particular xserver-xorg-core. The difference might actually be there. E.g. it might be interesting rebuilding the Debian driver package against the Ubuntu X server and vice versa and seeing what happens in each case. -- Earthling Michel Dänzer | http://www.vmware.com Libre software enthusiast | Debian, X and DRI developer -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe".
