Hello
Mrview need openGL version 3.3, but I can not have it ... (because of my
intel card ?)
I even try to update intel package from testing,
(apt-get -t testing install intel-microcode)
but I get the same
glxinfo |grep version
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
OpenGL core profile version string: 3.1 (Core Profile) Mesa 10.1.4
OpenGL core profile shading language version string: 1.40
OpenGL version string: 3.0 Mesa 10.1.4
OpenGL shading language version string: 1.30
mrtrix compile, but when running mrview I get the erreur
mrview [ERROR]: your OpenGL implementation is not sufficient to run
MRView - need version 3.3 or higher
GLSL log [vertex shader]: 0:1(10): error: GLSL 3.30 is not supported.
Supported versions are: 1.10, 1.20, 1.30, 1.00 ES, and 3.00 ES

It is generally important to differ between OpenGL version and OpenGL core
profile version. My intel card has core profile 3.3 and OPenGl 3.0. You can
query all relevant version numbers via
$ glxinfo | grep version
glxinfo is in the mesa-utils package. I assume you now have OpenGL core 3.3
since you have a recent version of Mesa. If not, this might also be caused by
your intel kernel driver or intel xorg driver.
Does mrtrix not compile? What exactly is the problem right now?
Cheers

Hi
the best is to have an nvidia card (and not the intel chipset) I
will remember for my next laptop.
For now it seems that testing or sid will not work for my case
Why do I still have openGL3 with mesa 10 ?
Checking for OpenGL: 3.0 Mesa 10.1.4
It is not clear to me which package give me the openGL
In have in version 10.1 :
libgl1-mesa-dev
libgl1-mesa-glx
libgl1-mesa-dri
liglapi-mesa
mesa-common-dev
but libglu1-mesa (and libglu1-mesa-dev) are now with version 9.0
It seems to me that the opengl soft depend on libglu1-mesa, but I
can not find higher version
Thanks

This is unfortunate indeed. But maybe it is time to update :-). You
could update the kernel the same way you updated Mesa to get the latest
intel driver. But then you might be required to update the xorg driver
too, this might trigger updates of Xorg, triggering updates of ......
We develop a visualization tool and also rely on modern OpenGL support.
We often encounter the same problem you now have with our users. We
usually recommend updating to testing or sid due to the hassle you might
get into when selectively updating some X packages. If you require the
latest driver features then you probably don't have another choice.

Hi
In the link you gave it is states
"Many people seem to be afraid of mixing stable with testing, but
frankly, testing is fairly stable in its own right,"
but I am not so sure : I now have mixing problem...
it seems that all opengl application now complains
Gen6+ requires Kernel 3.6 or later.
(i currently have Linux rr 3.2.0-4-amd64 #1 SMP Debian 3.2.57-3
x86_64 GNU/Linux)

Hi
Thanks for the info, I tried to reinstall (with the option -t
testing) all lib that was install and that contain mesa
libgl1-mesa-dev
libgl1-mesa-glx
libgl1-mesa-dri
liglapi-mesa
mesa-common-dev
those were update to version 10
but libglu1-mesa (and the dev)
are now with version 9.0
and mesa-utils is still in 8.1
but now the ./configure part of mrtrix instead of telling me I
have openGL 3.0 with mesa 8
it says
Checking for OpenGL: not found
WARNING: no OpenGL implementation found.
Some of the graphical user interface components may not
be stable on
this system.
Any idea of which pakage I miss or which I should remove ?
Many thanks

Hi there,
Wheezy provides Mesa 8. This complies to OpenGL 3.0. For 3.3
compliance, you will need Mesa 10. This is available in Jessie
an Sid. You can install the latest MESA packages from Testing
or Sid. You might take a look at this ServerFault thread:
http://serverfault.com/questions/22414/how-can-i-run-debian-stable-but-install-some-packages-from-testing
I hope this helps somehow.
Cheers,
Sebastian

Hello
I would like to run the new mrtrix viewer (mrtrix3) but there is a
strong dependance on OpenGL 3.3
because of my graphic card, I use libglu_mesa than
correspond to openGL 3.0
is there a way to update to openGL 3.0 ?
I am running dell laptop with
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation

Many thanks
