Looking at xorg-server source I did not see anything that points it must link to libthr, perhaps HAL support makes libthr linking mandatory. X doesnt crash on exit for me, well it did before (maybe because drm outputs ressurected *pipe disabled* message on console all the time). Should this finnaly be replaced with DRM_DEBUG ? -- Paul
