https://bugzilla.novell.com/show_bug.cgi?id=867499 https://bugzilla.novell.com/show_bug.cgi?id=867499#c5 --- Comment #5 from Tyler Kay <Tyler_Kdog@Yahoo.com> 2014-04-02 15:08:19 UTC --- As I noted in the openSUSE forums yesterday, I tested with the latest package updates (kernel 3.14, X, etc ) and proper functionality has been restored (i.e. you can once again achieve a large contiguous desktop using a non-PX radeon + radeon system). As I applied the updates en masse, I certainly could not pinpoint what resolved the issue. A glance at the server's change log revealed nothing related to randr (though, in relation to commentary in this thread, I do note that the in server glamor changes, discussed just above, are indeed documented). At that point, I suspected that it was probably a change to the kernel driver, and was going to leave it at that. However, curiosity got the better of me, and, upon checking the drm updates applied to kernel 3.14, we do indeed find this: http://cgit.freedesktop.org/~agd5f/linux/commit/?h=drm-fixes-3.14&id=7848865914c6a63ead674f0f5604b77df7d3874f Which looks strongly to me to be the winner/solution/explanation. Users of other adapters (ex. nouveau, intel) should check to see if similar runtime PM logic has been adopted in the respective DRM/kernel driver. Alex no longer owes me a beer. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
