opengl-3.1 with intel graphics

[Neal Becker]

I have
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 5500 (rev 
09)

glxinfo | grep OpenGL
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 5500 (Broadwell GT2) 
OpenGL core profile version string: 4.3 (Core Profile) Mesa 12.0.1
OpenGL core profile shading language version string: 4.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 12.0.1
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.1 Mesa 12.0.1
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.10
OpenGL ES profile extensions:

But if I select opengl 3.1 in settings/display/compositor, it doesn't work 
reliably.  It seems sections of screens are often not updated.  This doesn't 
happen if I select opengl 2.

I read that intel opengl depends on mesa, and whatever mesa claims to 
support should work.  Doesn't seem to, any ideas?

Have you considered giving

	dnf remove xorg-x11-drv-intel

a try?

Thanks!  That seems to be working fine.
But I don't seem to be able to get DRI3 working.  I've read various posts, 
and tried

Section "Device"
    Identifier  "Intel Graphics"
    Driver      "modesetting"
    Option      "AccelMethod"    "glamor"
    Option      "DRI3"            "1"
EndSection

and

Section "Device"
    Identifier  "Intel Graphics"
    Driver      "modesetting"
    Option      "AccelMethod"    "glamor"
    Option      "DRI"            "3"
EndSection

But I just get
[     7.324] (WW) modeset(0): Option "DRI3" is not used
[     7.324] (II) modeset(0): [DRI2] Setup complete
[     7.324] (II) modeset(0): [DRI2]   DRI driver: i965
[     7.324] (II) modeset(0): [DRI2]   VDPAU driver: i965

man intel and man modesetting

in intel man page you got: Option "DRI" "string"
but not man page of modesetting ... 

I also will try modesetting soon.


Thanks for the tip,

Looking here:

https://bbs.archlinux.org/viewtopic.php?id=212509

I'm not sure what that means.  If I do:
LIBGL_DEBUG=verbose glxinfo | grep libgl
...
libGL: Using DRI3 for screen 0

OK, so dri3 is getting used for somethings?  (but only screen 0?? I have 2 
screens)
