Looks like your X server isn't built with present support and the intel driver is requiring it.  This is either a problem with your build or an intel DDX bug.  In any case, it's not a mesa bug.

So what should I do to fix it ? Should I recreate this report on another component (DDX) or what ? I

Wrong, very wrong.

A mesa provided function (createNewScreen) is reporting a failure.

Sorry, I missed that.  I saw the first error and didn't notice the others.

That seems odd.

Eugene, Did this recently start happening?  Does it work with an older mesa?  Unfortunately, those logs aren't telling me much about what actually happened.

Also, what graphics chipset do you have?  From the Xorg.0.log, it looks like an 865G.  An lspci would be helpful

>Did this recently start happening?  Does it work with an older mesa?  Unfortunately, those logs aren't telling me much about what actually happened.

With older MESA I have described situation here: https://bugs.freedesktop.org/show_bug.cgi?id=86583

For any additional info, please ask.

Could you go back to the semi-working configuration you had before and get a glxinfo from it.  I can't tell what mesa driver is being called.  We have two different i915 drivers in mesa and knowing which would be useful.

Another thing that would be good to try is to set AccelMethod to "uxa" in your xorg.conf and see if that makes a difference.  I don't know that it will, but it would make a good datapoint.

Yes. But, please, specify what do you mean on "semi-working"? What kernel, what mesa version?

Under "semi-working" configuration or under as it is now ?

Xorg.0.log (UXA acceleration)

On current configuration.

I was able to fake my computer into thinking it was an i915 and the driver loads ok.  I'm guessing someone pushed something that broke indirect rendering.  I'll try to look at it next week.

Thanks.

Greetings. I just updated to latest Mesa git and drm-intel-nightly after which new backtrace and even GPU crash appeared again. Mouse pointer is late now for hand movements. Although it says acceleration is turning off I feel some performance acceleration and higher responsiveness in comparison to how it was before those backtrace and GPU crash appeared again.

FWIW... only the "classic" driver supports GEN2 (i830, i845, and i865) chipsets.

Just a little update. Latest Mesa git and drm-intel-nightly #201501220251. Issue with mouse is gone and now it's ok. But OGL rendering still not starting:

$glxinfo | grep error
libGL error: failed to create dri screen
libGL error: failed to load driver: i915

Trying to logoff gives black screen. And the following in logs:

I tried this on a pineview machine which is i915 not 865 but it works fine, so this doesn't look a generic driver change.

So what could I/we do ? Any ideas ? May be some kind of any additional tests ?

As I understood configuration you tried not the same that I have. So there are differences in them. But I can give you SSH access so you'll be able to determine the cause of the problem. Is this option suits you ?

I tried stable MESA 10.1.3 with kernels 3.13.0-45 and 3.18.5. It works without any problems. But installing latest MESA git immediately causes OpenGL not to start with following errors:

libGL error: failed to create dri screen
libGL error: failed to load driver: i915

So the problem is in MESA, after 10.3.1.

same here, it seems.
