Yup, it is from commit 1a489142c8e6a4828348cc9afbd0f430d3b1e2d8 Author: Chris Wilson <[email protected]> Date: Tue Oct 23 23:43:50 2012 +0100 sna: Disable RandR hotplug events if Xinerama is enabled Since RandR itself is disabled if Xinerama is enabled, for example with ZaphodHeads, calling RRGetInfo() upon a hotplug event generates an assertion. Reported-by: Stephen Liang <[email protected]> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=55260 Signed-off-by: Chris Wilson <[email protected]> and covers a quite obscure mix of features that results in no RandR. Hmm, now with the link-status property there is a reason why the ddx might want to handle hotplug even if it doesn't propagate the event on, but so far link-status DP retraining in userspace is an i915.ko only "feature". -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Nouveau mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/nouveau
