Initializing JOGL on a laptop with switchable graphics

Hello,

When trying to initialize JOGL on my laptop with two graphics devices (internal is Intel HD Graphics 520, secondary is AMD Radeon R7 M360), I get an exception saying there is a problem with shared resources. I setup my application to use the radeon gpu via the radeon settings which seems to run fine. I couldn't detect any issues when running the application this way though.

Hello

I'm not sure that this problem is caused by the presence of two GPUs.

Just as a reminder, what you do is fine, most softwares using OpenGL are unable to handle a change of GPU at runtime, disabling Optimus or similar technologies by choosing which GPU to use is the way to go.

Since it does not involve any issues in the application itself it seems to be fine. Just wanted to check in case I did something wrong there. Thank you for the quick reply.

You're welcome. It just tries to use EGL and it fails.
