backport fix from mesa-7.9	none

Description Fabrice Bellet 2010-06-08 11:11:29 UTC

Something changed in mesa-0.7.8-3 (0.7.8-2 was ok, and 7.9-0.1 is ok again), that prevents FlightGear to obtain a visual with the needed requirements. I could reproduce the bug with the nouveau driver, and the radeon driver too.

The relevant part of the code is in OpenSceneGraph-2.8.2/src/osgViewer/GraphicsWindowX11.cpp:266 (function GraphicsWindowX11::createVisualInfo())

The pushed attributes are:

GLX_USE_GL
GLX_RGBA
GLX_DOUBLEBUFFER
GLX_RED_SIZE 8
GLX_GREEN_SIZE 8
GLX_BLUE_SIZE 8
GLX_DEPTH_SIZE 24
GLX_STENCIL_SIZE 8

Comment 1 Fabrice Bellet 2010-06-08 21:54:58 UTC

aaah, the LIBGL_DIAGNOSTIC variable helped me to find the problem :
WARNING: unknown GLX tag from server: tag 0x1 value 0x4
WARNING: unknown GLX tag from server: tag 0x1 value 0x4
Error: Not able to create requested visual.

-> GLX_RGBA is considered as the value the (unknown) tag GLX_USE_GL

Comment 3 François Cami 2010-07-28 21:53:09 UTC

I've reproduced the bug with:
mesa-libGL-7.8.1-6.fc13.x86_64
FlightGear-2.0.0-1.fc13.x86_64

I've verified that the attached patch fixes the bug.
srpm: http://fcami.fedorapeople.org/srpms/mesa-7.8.1-7.fc13.src.rpm
spec: http://fcami.fedorapeople.org/srpms/mesa.spec
Feel free to edit the changelog.

Warning, the current libdrm-devel in F13 breaks the Mesa build.
I had to downgrade to libdrm-devel-2.4.20-1.fc13 to rebuild Mesa.
