Comment 70 for bug 419328

It seems pretty clear that the problem is that arandr, gnome-display-properties et. al. are requesting display sizes that are bigger than the maximum texture size that can be supported by the i945gme chipset. The problem really needs to be fixed in at least two places though, the tools shouldn't request sizes that are bigger than the maximum texture size compiz will be able to obtain, compiz should be guarded to make sure it doesn't request oversize textures and fallback gracefully and the driver shouldn't lock hard if it is requested to provide a texture size bigger than it supports. Defence is depth is required otherwise this can be used to DOS a machine even if the userland tools are fixed up.
