Error Message when opening Cura

[kenny 2]

Was using Cura all day then all of a sudden I got this error message when I was opening it.

 

"Could not probe OpenGL. This program requires OpenGL 2.0 or higher. Please check your video card drivers."

 

Any Idea what it means?

Are you perhaps using Cura over a remote desktop connection?

 

There is a known problem when starting Cura over RDP, Windows tells Cura that a new "context" for 3d rendering can not be created because there is no GPU present. If Cura had already been running prior to starting the RDP connection, Cura can in fact use the GPU. There is nothing Cura can do about this, and it does not just affect Cura either.

 

Recently, NVidia published a patch of sorts to fix the issue, if the computer running Cura has an NVidia GPU: https://www.khronos.org/news/permalink/nvidia-provides-opengl-accelerated-remote-desktop-for-geforce-5e88fc2035e342.98417181

Thanks ahoeben

Yes it does have an Nvidia card.

GeForce 1070.

So that patch should fix it?

   I did get it fixed. I went to the NVidia web sit and downloaded "GeForce Experience". With that I was able to check for updates for the video card. It found one, I installed it and it's working ok. 

   When I checked in Device Manager for updates for the card it said I had the latest update. Which obviously I didn't.

So, so far so good. 

  Also the sleep option was missing from the shut down, restart, sleep options. After the driver update it reappeared.
