OK, thanks for the information. >That said, a few people above mention that kernel 2.6.29 or newer solved >their problem. Have you tried that? Yes, I tried a 2.6.29 kernel (the one from http://kernel.ubuntu.com/~kernel- ppa/mainline/v2.6.29.6/) but it did NOT solve the problem for me. I will try the earlier kernel 2.6.29.2 (from http://kernel.ubuntu.com/~kernel- ppa/mainline/v2.6.29.2/) which was reported by "aya" to be successfully solve the problem. Maybe it just works with very specific kernel versions. Do you have other suggestions what to test? I would really like to invest some time to help solving this problem as it is very annoying. Another note: Many people are saying that X only freezes when they run 3D/OpenGL applications but I get freezes without running such apps and without having any desktop effects enabled.
