          Priority: medium
            Bug ID: 81689
          Assignee: dri-devel at lists.freedesktop.org
           Summary: Black screen in info-beamer
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: sa at whiz.se
          Hardware: x86 (IA32)
            Status: NEW
           Version: 10.2
         Component: Drivers/Gallium/r600
           Product: Mesa

The multimedia presenter info-beamer ( http://info-beamer.org/ ) just renders a
black screen with r600g. 

It's working fine with software rendering and on Intel hardware.

Not a regression, or at least present in Mesa 9.2.

I've made an apitrace of one of the beamer demos:

The trace renders correctly but gives a lot of errors, so this might be a bug
in info-beamer:

0 87813 glGetUniformLocation(program = 0, name = "Color") = -1
87813: warning: glGetError(glGetUniformLocation) = GL_INVALID_VALUE
87872: glDebugOutputCallback: High severity API error 1, GL_INVALID_OPERATION
in glReadBuffer(buffer=0x405)
87872: glDebugOutputCallback: High severity API error 1, GL_INVALID_OPERATION
in glDrawBuffer(buffer=0x405)
0 87872 glPopAttrib()
87872: warning: glGetError(glPopAttrib) = GL_INVALID_OPERATION
87882: glDebugOutputCallback: High severity API error 1, GL_INVALID_VALUE in
glGetUniformLocation
