Xorg changes? Nouveaux prefered over NV? How can I tell?
I have a sqeeze system running as (amongst lots of other things) a mythtv backend/frontend combination. Yesterday, after a long overdue aptitude update, I noticed the video playing rather slow. I had previously configured the nvidia kernel module to run because it seem to perform better with mythtv Looking at my Xorg.0.log file, it appears that the nv driver is being loaded, but then unloaded and glx also fails to load. the nouveau driver also appears to be loaded (I can see it starting up and I don't see it failing - although the vesa driver also seems to start up. (==) Matched nouveau as autoconfigured driver 0 (==) Matched nv as autoconfigured driver 1 (==) Matched vesa as autoconfigured driver 2 (==) Matched fbdev as autoconfigured driver 3 (==) Assigned the driver to the xf86ConfigLayout (II) LoadModule: nouveau (II) Loading /usr/lib/xorg/modules/drivers/nouveau_drv.so (II) Module nouveau: vendor=X.Org Foundation compiled for 1.7.7, module version = 0.0.15 Module class: X.Org Video Driver ABI class: X.Org Video Driver, version 6.0 (II) LoadModule: nv (II) Loading /usr/lib/xorg/modules/drivers/nv_drv.so (II) Module nv: vendor=X.Org Foundation compiled for 1.7.7, module version = 2.1.17 Module class: X.Org Video Driver ABI class: X.Org Video Driver, version 6.0 ... further down the file, and with no warning as to why (II) UnloadModule: nv (II) Unloading /usr/lib/xorg/modules/drivers/nv_drv.so ...

No xorg.conf, so its doing it automatically. I am not worried about all the probing etc - unless it gets the wrong answer. This is in essence a headless server which runs 24/7 so hardly ever restarts.
