The programm seems to work normally. But the startup log says:

 Detected: OpenGL "2.1"
 Driver version string: "2.1 Mesa 10.3.2"
 GL vendor is "Intel Open Source Technology Center"
 GL renderer is "Mesa DRI Intel(R) Ironlake Mobile "
 GL Shading Language version is "1.20"
 MESA Version Number after parsing:  10.3
 Mesa version is fine, we should not see a graphics problem.
 GLSL Version Number after parsing:  1.2
 This is not enough: we need GLSL1.30 or later.
 You should update graphics drivers, graphics hardware, or use the MESA version.
 Else, please try to use an older version like 0.12.4, and try there with --safe-mode
 Config option main/ignore_opengl_warning found, continuing. Expect problems.

This is 4-5 year old thinkpad T510 with graphic card:

Hi Martin,
could you be more specific what the problem is?
It seems that you have an older bersion of GLSL and *could*
experience some problems, but you don't. That should be
a reason to rejoice rather then to submit a bug, right? :D

Some relevant information:

It seems that some GLSL 1.30 functionality exists for Ironlake GPUs,
but something is still missing so only GLSL 1.2 is advertised.
Fortunately, there is enough so that you can use stellarium just fine.

I think it should be reassigned to one of mesa packages.
