I copied the two messages, and compared them side-by-each in xterms. When X realizes that you have an Nvidia card, and no xorg.conf, it sets up a list of all drivers that could possibly work with your card, and goes around probing, trying to find them... [ 20.299] (==) Matched nouveau as autoconfigured driver 0 [ 20.299] (==) Matched nv as autoconfigured driver 1 [ 20.299] (==) Matched nouveau as autoconfigured driver 2 [ 20.299] (==) Matched nv as autoconfigured driver 3 [ 20.299] (==) Matched modesetting as autoconfigured driver 4 [ 20.299] (==) Matched fbdev as autoconfigured driver 5 [ 20.299] (==) Matched vesa as autoconfigured driver 6 [ 20.299] (==) Assigned the driver to the xf86ConfigLayout The OK version reports as follows... [ 32.691] (II) LoadModule: "nouveau" [ 32.691] (II) Loading /usr/lib64/xorg/modules/drivers/nouveau_drv.so ...followed by failure messages as it attempts to load "nv" (Nvidia binary blob), modesetting, fbdev, and vesa. It only finds nouveau, and works with it. The NG version reports... [ 20.299] (II) LoadModule: "nouveau" [ 20.314] (II) Loading /usr/lib64/xorg/modules/drivers/nouveau_drv.so [ 20.523] (II) Module nouveau: vendor="X.Org Foundation" [ 20.523] compiled for 1.15.0, module version = 1.0.10 [ 20.523] Module class: X.Org Video Driver [ 20.523] ABI class: X.Org Video Driver, version 15.0 [ 20.537] (II) LoadModule: "nv" [ 20.537] (II) Loading /usr/lib64/xorg/modules/drivers/nv_drv.so [ 20.607] (II) Module nv: vendor="X.Org Foundation" ***IT'S LOADING BOTH NOUVEAU AND NV (NVIDIA BINARY BLOB) DRIVERS***. As you've noticed, that doesn't work very well. You need to get rid of the Nvidia binary blob drivers. The options are... Plan A) unmerge the Nvidia binary drivers Plan B) if Plan A fails, manually remove /usr/lib64/xorg/modules/drivers/nv_drv.so - Walter Dnes <waltd...@waltdnes.org> I don't run "desktop environments"; I run useful applications
