I've been testing jogl 2.1.1 on a new Intel NUC (DC53427HYE) in Ubuntu 13.04 and have been receiving the following error message after the application crashes:

intel_do_flush_locked: No such file or directory

I tried to step through the application to see where it fails and it fails when the ClassLoader.findNative returns successfully when searching for 'Java_jogamp_opengl_gl4_GL4bcImpl_dispatch_1glFinish1__J' from 'libjogl_mobile.so' (I think).

I have my GLCaps set to GL2 so I'm surprised a bit that it's using a GL4bcImpl at all (also, we used to use GL2GL3 but it returns false for isGL2() now; is that new or just specific to this new hardware? I don't see issues on other systems after the update to 2.1.1).

Any ideas as to why this might be happening? I've tried the Intel HD 4000 drivers as well as the mesa drivers from ppa:ubuntu-x-swat/x-updates and ppa:oibaf/graphics-drivers as per some suggestions online. I tried running a trace on the GL object but all I get is a glViewport call before the crash; the code seems to create my vbo geometry, draw it, and then crash upon calling glFinish().


Thanks for any insight.
