I have a lenovo y400 laptop and I'm having brightness adjusting problems. The nvidiabl module cannot start normally and I got information by typing command "dmesg | grep -i nvidiabl":
[ 15.996031] nvidiabl: loading driver version 0.84
[ 15.996037] nvidiabl: LENOVO - 20192 model detected in DMI tables
[ 15.996042] nvidiabl: No supported Nvidia graphics adapter found

There really exists NVIDIA GT650M card but nvidiabl can't detect it, Maybe it's because the graphic driver hasn't been loaded yet when nvidiabl is starting?... I have no idea about and hope anyone can help me solve this problem...By the way, thank you for this amazing job!
