This is quickfix how to get rid of errors : “You are not currently using a display attached to an Nvidia GPU”. Make sure you already install the latest Nvidia Driver (use updates) from Nvidia (not Lenovo).
Then, checkout on Bios settings for graphics to use “switchable mode”. If everything is fine, now first step we should do is uninstalling Intel4000 VGA driver.
1 | Window Key + X -> Device Manager -> Display Adapters -> Uninstall Intel |
Then reboot. After we re-logged, then try open Nvidia Control Panel in systray. If the errors still occurs, re-install your Nvidia drivers. That’s will solved the problem.
Later, we realize that brightness doesnt works here. All we need just go to regedit. (Window Key + R) and type “regedit”. find key “EnableBrightnessControl” inside “HKEY_LOCAL_MACHINE/SYSTEM/”. Also, install Intel4000 driver to make it’s works. Reboot to see the results
