Error "NVAPI call returned -180" after consecutive runs #262

Closed tobi-tobsen closed 7 years ago

tobi-tobsen commented 7 years ago

Hi, I am getting the following error:

Error Rendermanager: OSVR Rendermanager Warning: got error from nvidia API: NVAPI call returned -180 (hex: ffffff4c) nvapi invalid configuration. Could not aquire display access for vendor Id 44806 for display 0. Rendermanager D3D11Opengl::OpenDisplay Cant open d3d11display

When I am getting this error right after booting the system, unplugging and replugging the HDK2 sometimes helps.

However, consecutive starts of the application result in the aforementioned error. This also happens with the osvr samples.

I am using the HDK2 in direct mode on a zotac en970, windows7 x64 and Nvidia drivers 373.06.

Here are the logfiles of the server and the application. app_2016-11-09_14-56.log.txt osvr_server_2016-11-09_14-56.log.txt

I'm assuming you're putting the HDK into direct mode (with enabledirectmode) before starting the apps.

Can you post the output of DirectModeDebugging?

tobi-tobsen commented 7 years ago

Yes of course. Here is what I did:

  1. Set Direct Mode with enabledirectmode
  2. Launched DirectModeDebugging (Setting direct mode worked, see directmode.log.txt)
  3. Launched the HighPolyOpenGL sample which fails
  4. Launched DirectModeDebugging (DirectMode is no longer enabled, see directmode_2.log.txt )

Update: This is also happening on a NVIDIA GeForce GTX 1070 8GB GDDR5 "VR Ready" System. Unfortunatly, I cannot get the logs of this system just now, but I strongly suspect that it is the same issue. Any idea what is causing it?

rpavlik commented 7 years ago

Direct mode debugging exits direct mode, so if your config is set up to be direct mode, you'll need to run the enter direct mode app again after running debugging.

Also, try the preview firmware linked in Reddit.

@rpavlik Great, the firmware update postet on reddit worked! I can now use the HDK2 with zotac en970, windows7 x64 and Nvidia drivers 373.06 in direct mode and consecutive starts of the application and samples still work. Good job!
