Thanks for testing and the feedback. I've gone ahead and applied the
patch to our ubuntu-precise kernel git repo. The fix should be
available in the next upload we do. Thanks.

I'd really like to get this fix applied before Beta-2 for Precise. If I
could just get test confirmation with the kernel from comment #71, that
would be great. Thanks.

Leann,
I'll try to test it this weekend.

Leann, the kernel mentioned in comment #71 seems to perform about the
same as the drm-next one. xrandr operations take about 170ms on my
hardware. So it would seem you have successfully applied the patch. :)

Hi,
I have built an Precise 12.04 Ubuntu test kernel with the patch noted in
comment #69 applied. Could you please test and let me know your

For me, under kernel 3.0.0-16-generic, running xrandr takes ~1.4 seconds
and it appears to stall my system while running. With 3.3.0-996-generic
#201202170408 from the drm-next area above, running xrandr takes ~170ms
and doesn't cause my system to stall (at least noticeably). So for me,

Allegedly the patches have now hit the drm-next kernel, Ubuntu builds of
which are here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-next/
It would be helpful if someone able to repro this problem could install
that kernel and verify that the issue is gone there.

Btw, the upstream discussion indicates that the patch has been tested on
intel but maybe needs wider testing to ensure it doesn't cause erroneous
behavior on radeon and nouveau drm drivers. Thus, it would be
reasonable for kernel team to block on seeing these patches appear in
the upstream kernel
Jason Warner has hardware that reproduces this bug (see #884348).
It does not look like there's much else to be done on the X side, so I'm
closing out the last X task. I think it's just a matter of waiting on
this to work its way through kernel team processes.

See also bug 859389 where I have an incorrectly named HDMI1 output, on
a machine with no HDMI ports.
The difference is, I am using HDMI1. It's actually a Display Port with
a DVI adapter.

Easy way to set that parameter: Run 'sudo xdiagnose', then in the GUI
tick the first checkbox (Graphics debugging), exit, and reboot. Then
collect your dmesg and it should have the required debug info.

It shouldn't even load the module if the device is not supported by it.
Looks like there's a genuine bug then.
Can you try first installing the machine with the safe mode, and then
install a 3.1rc mainline kernel to see if it boots normally?
