the blacklist file prevents Nouveau from loading, but if you need to double check that it actually worked you use 'lsmod' I pipe the output to grep to shorten the list:
$ lsmod |grep nouveau This will output a single line if it finds the nouveau kernel module, or do nothing if nouveau is not loaded. Do the same for the nvidia driver: $ lsmod |grep nvidia If both drivers are loaded at the same time, you will have problems If neither driver is loaded, you will have 2D performance only. If nouveau is loaded, but NOT nvidia then nvidia-settings will crash and burn. Find which of the 2 modules you have currently loaded in your kernel with lsmod, Then check the nvidia packages you have installed: $ ls /var/log/packages/ |grep nvidia None of the above suggestions are fixes, just triage. What is broken depends entirely on the output of lsmod vs the nvidia programs you have installed.
