what does 'lsmod' say?
There you could see which modules are currently running.
check if the driver is installed correctly:
cd /lib/modules/`uname -r`/kernel/drivers/video
ls |grep NVdriver |wc -l
if the answer is 0 then the driver is not installed
if the answer is 1 (or more), then do 'insmod NVdriver' and check if it is running with 'lsmod'
(EE) Screen(s) found, but none have a usable configuration
Delete your XFconfig-4 file and regenerate with 'Xconfigurator'. And know tell the correct video modes for your monitor.
Then read the manual in section3: configure the XFconfig file (or something)
then it should work
