Since we allocate the front buffer dynamically for KMS, we could probably let the maximum virtual size be 4k or so (which I think really is the 2d limit). In principle, well-behaved GL apps are supposed to check the GL_MAX_VIEWPORT_DIMS limit, since that's the maximum window size that's expected to work. So if compiz were well-behaved, it would refuse to run if the root window were larger than that. Whether compiz actually _does_ that is another question, of course. But I think changing the max virtual to 4k for intel 915 and 945 might be a less bad set of tradeoffs. - ajax
