i've tried running your command, modprobe nvidia
in the sbin directory, it does nothing linux tells me he
bash: modprobe: command not found.
but when I look in the display section of the config...
it tells me that nvidia driver is loaded, and I saw the logo when X started... so this means everything is loaded, despite nv_check says kernel module isn't loaded...
Am I right??
Thanks again for helping me...
