Problem (OpenGL) with the launch of CURA 4.8

[AlexLewson 0]

I can not start CURA 4.8. Writes that there is a problem with OpenGL. Demolished Cura and the video card, cleaned everything, including the registry. reinstalled. The problem remained. What can be, in which direction to look?

What GPU do you use? Can you check if there are updated drivers?

 

Running Cura via a remote desktop connection is not supported.

@ahoeben - Please consider me dazzled.

It is a windows/driver limitation. Windows RDP does not support OpenGL.

If you have an nVidia GPU, there's a special driver you can install that supports  OpenGL:

PS: don't "demolish" your GPU on my behalf...

For anyone interested, I've been using Cura remotely for some time with VNC.

 

I use UltraVNC server on a laptop with Cura. It works correctly as long as I keep the lid open (if the screen is off Cura and other applications freeze over VNC).

 

On the other PC I use VNCViewer by RealVNC but anything should work.

It might be worth trying to see if a HDMI dummy works. If your laptop has a VGA port, you might also try a VGA dummy, which is easier to make yourself. Both fool the computer, making it think an external display is connected.

Sorry for the delay in answering. Unfortunately, the logic of intent rarely coincides with the logic of circumstances.
The video chip is built into the i5 processor. The latest driver is installed.
I worked through RDP. Today I will finally get to the computer and look straight ahead.

Friends! Thanks to everyone who responded! The problem was resolved.🙂 The reason for this was the RDP. Directly СURA works great.
I'm sorry for the bad english.🙄

wtf?   Cura works fine over RDP, SO LONG AS YOU START CURA FROM ... NOT... RDP.

It is as if some dork put a useless/foolish/unnecessary openGL check at launch.

It works a bit differently. Cura asks the system "can you please provide me with the resources to use openGL?" and the system says "NO" when running over RDP.  Cura cannot do much without those resources, but apparently when it already has them it can continue to use them.
