"Failed to find any valid GLX configs" error on x11

[chris-montero]

• I am on void linux
• I have the proprietary nvidia 550.120_3 drivers.
• All the lines in my /var/log/Xorg.0.log file that contain the word "GLX" are the following:

@chris-montero Do you mind testing the RGFW c examples? This will let me know if it's a problem with the Odin binding (which is not up-to-date) or if it's a problem with RGFW itself.

[chris-montero]

@ColleagueRiley I did so, and some of them work fine with the C examples.

These examples fail, along with their error messages:

[ColleagueRiley]

I'm transferring the issue here because I believe the source of the issue is the original code.

Could you tell me more about your GPU? I mostly would like to know what the latest version of OpenGL it supports and if it supports Vulkan.

Also the log is time stamped at Fri Sep 13 10:02:06. So it may not be relevant to this issue.

[chris-montero]

I have an nvidia gtx 950.

glxinfo | grep "OpenGL version" outputs this:
OpenGL version string: 4.6.0 NVIDIA 550.120
Vulkan is supported. Just yesterday I was trying to set up the vulkan sdk for development, and I ran the provided vkcube executable, which ran without issues.

You're right, the log is old. I'll get a more recent version if you need it.

[ColleagueRiley]

@chris-montero I'll look into this issue as soon as I can. At the moment I am a bit busy. I believe the first error is caused by

this line on line 2543

XMatchVisualInfo((Display*) win->src.display, DefaultScreen((Display*) win->src.display), 32, TrueColor, vi); /*!< for RGBA backgrounds*/

@ColleagueRiley I did so, and some of them work fine with the C examples.

@chris-montero These first two bugs might be fixed. I'd need to know more about the last two errors to attempt to fix them.

[chris-montero]

you are correct, the first two work now. The last two don't. I don't know what kind of information you want from gl33, or how I could provide you with that info.

But about examples/vk10, I think you can look here to see how to set up validation layers and a custom debug messenger and then maybe I can run that and give you some information that way.

[chris-montero]

Btw I tried running vk10 in gdb, and this is the backtrace:

[ColleagueRiley]

@chris-montero I'll look into the vulkan example later. It's a low priority because it's an issue with an example and not with RGFW. Also for full disclosure, the vulkan example is based on contributed code rather than code I wrote myself.

I'm not sure how to start fixing gl33 issue. But it will require your assistance since the error doesn't occur with my hardware/drivers.

[chris-montero]

@ColleagueRiley for the gl33 example, if you can give me a patched version of the code that would produce more relevant information for you, I can run it and give you the output.

[ColleagueRiley]

@chris-montero I'm not entirely sure why that issue is happening. The error is a bit vague. It could mean, for example, that the window is just too large. Would you mind debugging the example and finding where the issue occurs?

[chris-montero]

@ColleagueRiley I tried to debug it with both gdb and lldb, but I guess that won't do much since it seems to be an x11 error, not a segfault or anything like that. I don't know what else to try. Do you have any suggestions?

[ColleagueRiley]

f93c2fd

Should fix your gl33 issue

[chris-montero]

This fixes the problem. You can keep this issue to keep investigating and find a more robust fix for gl33. or do whatever you want with it i dont really care
