I have to disagree with you about this. The lines: >> OpenGL vendor string: Tungsten Graphics, Inc >> OpenGL renderer string: Mesa DRI Intel(R) 852GM/855GM GEM 20090712 >> 2009Q2 RC3 x86/MMX/SSE2 >> OpenGL version string: 1.3 Mesa 7.6 indicate that a) the OpenGL implementation the 3D driver is using is Mesa, by Tungsten Graphics; b) that it is being hardware accelerated (DRI=direct rendering infrastructure). If this was not the case, that line would read: OpenGL renderer string: Software Rasterizer I think there may be a bit of confusion about this. I noticed that the VirtualGL documentation says "Install the vendor drivers for the server’s 3D graphics card. Do not use the drivers that ship with Linux, as these do not provide 3D acceleration or Pbuffer support. " But I thought the reason was that the docs weren't up to date. Actually, the OSS drivers provide 3D acceleration for ATI cards from R100 to R500 and there's already experimental support for more recent generations. Also, Intel cards have had 3D linux support since long ago. Regarding pixel buffers, I can't be so sure--especially with this very low end card of mine. However, the extension GLX_SGIX_pbuffer is present, and the Xorg developer who took a look at my glxinfo mentioned a couple of other extensions related to it (which I can't remember). Is there anything I can do to get to the bottom of this? I still don't discard the possibility that I haven't set up the whole thing properly, or that some oddness somewhere is causing problems with permissions or what have you. Also, I'll soon have another laptop of mine back with and ATI card, I could try with that one with both the proprietary and the open source driver.
