Black screen on Linux.

I'm running on Arch Linux, with an Intel HD 4000 iGPU.

Running PA alone produces some weird results, such the cursor being replace with a square image that looks like it's composed of PA resources, as well as other visible elements on screen, including the XFCE home folder. The images on the black screen are actually my cursor.

In the console, we find out that the GLSL shaders failed to compile, throwing the following error for each one:

Code:

0:1(10): error: GLSL 1.50 is not supported. Supported versions are: 1.10, 1.20, 1.30, 1.00 ES, and 3.00 ES

The first of the output tells us some version numbers:

Code:

[15:58:31.382] INFO OpenGL Vendor: Intel Open Source Technology Center
[15:58:31.382] INFO OpenGL Renderer: Mesa DRI Intel(R) Ivybridge Mobile
[15:58:31.382] INFO OpenGL Version: 3.0 Mesa 10.0.3
[15:58:31.382] INFO OpenGL Shader Language Version: 1.30

It should be noted that I am running the latest version of Mesa in the Arch repos, which happens to be 10.0.3. Apparently, OpenGL 3.2 support was added in Mesa 10.

Now, I'm under the impression that OpenGL 3.2 and GLSL 1.50 are supported by Intel HD 4000. However running this command:

Code:

MESA_GL_VERSION_OVERRIDE=3.2 MESA_GLSL_VERSION_OVERRIDE=150 ./PA

Gives me a segfault.

Code:

Not sure if I'm even heading down the right track, or if there is even anything I can do at this point. If so, could someone point me in the right direction? Or at least tell me if there is nothing I can do?

Thanks,

The parts of the output cut out had log and core dump information, which contained file paths, which XenForo for some reason considered links, not allowed in a New Member's posts.

Open source drivers (such as for Intel) and PA are a no-go situation at the moment. See also bug FS#3057. Let's hope they find a solution soon.
