What video hardware are you using, and what driver? I've had similar issues in the past myself with a variety of causes: - dodgy versions of mesa - dodgy versions of video drivers (both nouveau and radeon) - incorrect kernel settings, usually getting KMS wrong - incompatible combinations of framebuffer and KMS I don't recall any case where the problem was purely userland and the kernel systems were not involved hth -- Alan McKinnon [email protected]
