I have an intel chipset. However, if I uninstall the mesa driver on my system, the dependency break the x-server. Several games and also the xserverpackage itself seem to require the presence of mesa drivers (Gallium) on my system with i945 Intel graphics (this is a Lenovo X201). I will post var/log/Xorg.0.log right now as an attachment. Do you want also dmidecode?
