Hi,

This Intel DRI limitation, whether it be hardware or driver, still exists in Jaunty and Karmic.

When I put two 1280x1024 monitors side-by-side, I see:
  (EE) intel(0): Cannot support DRI with frame buffer width > 2048.
  and glxinfo says software rendering
When I put them one-above-the-other, I get full 2d hardware rendering and glxinfo says Mesa DRI Intel.

My only question is this: If this is a hardware limitation, with the Intel chipset, why isn't this also a limitation in WinXP? Am I misunderstanding something? OSX is mentioned above in the same vein, but the question wasn't really answered. One of the other duplicates to this bug mentioned the absence of the limitation in windows (Bug #360713).

I've looked around on the web, and I think this limitation is possible to work around ( http://lists.freedesktop.org/pipermail/xorg/2008-June/036151.html mentions two frame-buffers).

Thanks.
