Nvidia driver update problem

[KuRialv]

Hi guys, i just installed the new 301.42 WHQL driver and now when i want to open the nvidia control panel, it failed. it says no display attached to an nvidia GPU. i used the integrated hdmi connection. so any help here? i guess the nvidia optimus is gone when i installed the new driver?

Have you tried with a normal monitor?
I suppose your VG is compatible with the drivers, so I'm not going to ask if you checked.

Try unplugging the HDMI from the system, then plugging it back in.
