           Summary: Unigine Heaven/Vally: Multi monitor rendering does not
                    work
          Severity: normal

Unigine vally output

When trying to start the unigine demos with multiple monitors enabled (Wall 2x1
or any other of the options in the launch dialog), it will exit with a failure.

It seems that Mesa is using the compatability context which is limited to
OpenGL 3.0.

I've attached the output log of Unigine Vally when started with multi monitor
enabled.

The demos run fine when only a single monitor is enabled.

I'm currently using mesa-git g085f61b and linux 3.13.5 on Arch Linux with a
Radeon 5730.

The same issue can be seen when I try to enable dual output stereo 3D, which
should start two separate windows that it will render to.

Please attach your xorg log, dmesg output, and glxinfo output.  Additionally,
you'll need a 3.14 kernel for OpenGL 3.3 support with r600g.

I have now attached the requested outputs.

I thought that 3.14 was only needed for R7xx hardware to enable OpenGL 3.3 with
the core profile?

Atleast glxinfo reports version 3.3.

You are correct.  I misremembered.

It's up to the application to choose a compatibility or core context. Mesa
never has and probably never will support higher than 3.0 with compatibility
contexts. You'd probably have to ask the Unigine developers why it wants to use
a compatibility conext with GL_ARB_geometry_shader4 in this configuration.

I only reported this because the proprietary works in this case.

If this is an application bug, then I guess this can be closed as such. There
is no reason why Mesa should fall back to the compatibility profile when more
than one context is used I guess?

Presumably fglrx supports higher OpenGL versions and GL_ARB_geometry_shader4 in
compatibility contexts.

Mesa doesn't (couldn't) 'fall back' to the compatibility context. It means the
app didn't ask for a core context.
