Nvidia control panel not working after installing CUDA Toolkit

I am new to CUDA Development. I installed CUDA Toolkit 8.0 on my laptop running windows 10 home and has GTX 960M. Before Installing CUDA Toolkit, the context menu on desktop (right-click on desktop) used to have an option to access Nvidia Control Panel. And there also used to be system tray icons for accessing GeForce experience and GPU Activity status icon.
But after Installing CUDA Toolkit, these icons and options are no longer visible. And when I try to launch the Nvidia control panel from the System control panel, an error dialog box appears stating - “Nvidia Display Settings are not available. You are not currently using a display attached to Nvidia GPU.”
I don’t understand what this means. Did mess-up the CUDA Toolkit Installation? Do I have to re-install the Display Drivers?

Note: During the installation, I deselected the Display Driver, GeForce Experience and PhysX from the options because I already had the latest up-to-date versions of the respective tools installed on the system.

Please help, I don’t know what to do…!!!

I currently have the same issue.

Laptop using the 1050 using the 378.49 driver, the context menu option for the Nvidia control panel disappeared, and manually running the file triggered the same error as mentioned above.

Issue appeared after installing the CUDA 8 toolkit while deselecting the driver and Physx option.

Here is the current dxdiag output:

CUDA still works fine, and tensorflow on Win 10, Python 35 has the following output:

I posted the same question on StackOverflow, and got this solution: http://stackoverflow.com/questions/41658308/nvidia-control-panel-not-working-after-installing-cuda-toolkit-8-0. This worked for me. I did the following.

  • Uninstall CUDA and the Nvidia Display Drivers (if needed use DDU).
  • Install CUDA with all the components (custom installation --> CUDA+PhysX+Graphics Driver+GeForce Experience)
  • After CUDA installation restarts the computer.
  • Then install the latest Display Drivers (custom installation --> Graphics Driver+GeForce Experience+PhysX)
  • Immediately after installation, Restart the system.
    Now Everything should work fine (CUDA + Control Panel)

There are many users who have complained that their Control Panel is not opening. This error has reach over many Windows versions including 7 to 10. People who try to open the NVIDIA Control Panel through Start menu doesn’t work. Also by examining Windows Update explains that your drivers are outdated but actually they are not old. Here we have some solutions to fix this issue but in case you want to go for detailed solution then you can visit this website https://appuals.com/fix-nvidia-control-panel-wont-open/.

Method 1- Turning off Quick Boot: You can fix it by entering your system’s BIOS settings and turn off Quick Startup or Quick Boot. You can also gain access to the BIOS while utilizing any of the keys: Esc, Delete or F2 to F8, F10 or F12.

Method 2- Update .NET Framework and VC++ Redistributable: NVIDIA apps start on .NET Framework and VC++ Redistributable. Otherwise, you can also run a Windows update by tapping the Start button, write Windows Updates, click Enter and tap the option of Search for Updates.

Method 3- NVIDIA Display Driver Service: Tap the Windows + R keys to start the run prompt. Then write services.msc and click Enter so you could open the Services console. Find the option of NVIDIA Display Driver Service and double-click. Manage the Startup type into the Automatic and boot the service in case it’s not working. Do it exactly the same for other NVIDIA-related services. Try to start the NVIDIA control panel and confirm in case the error has fixed or not.
