xorg does not automatically use the nvidia driver without setting this in /etc/X11/xorg.conf. Or did you find a way to do so? In that case we would like to learn this. An xorg.conf with Driver="nvidia" breaks on other systems. Please check Xorg.0.log on the nvidia machine to see which driver you are really using. nvidia has its own accelerated libGL.so.1 library which replaces the system one which is from mesa. There is also a custom libglx.so Xorg module which replaces the one from X.org. Of course these need the nvidia driver to be functional. While it is now possible to configure the libGL.so.1 and libglx.so via alternatives, there is nothing that does autodetection and selects the optimal setup for the current system. Please send me the output of update-alternatives --display libGL.so.1 > nvidia doesn't use kms, but I quite shure, that xorg loads nvidia > driver (if > nvidia card presents), not udev by accessing /dev/nvidia0 or > /dev/nvidiactl, > anyway xorg loads modules for non kms drivers. In case the device nodes are missing in /dev, does Xorg really load the kernel module? Andreas -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
