Unable to launch

[NoozAbooz]

Hello, I just downloaded this. When I try to launch a version or profile with the launcher, a window quickly opens, then closes. After that, nothing happens.

Which version are you using?

[NoozAbooz]

I tried all 4 default versions but none worked. I launched it from the terminal, and here's the output when I choose a version:

Which version of Debian are you using?

[NoozAbooz]

I'm using the latest version of raspbian(buster)

[nobody5050]

Would you mind restarting your pi and trying again?

[NoozAbooz]

I restarted, but it still says the same thing.

Hello!

I'm pretty sure it is an OpenGL/EGL/MESA/VirGL problem. What is your memory split? And which RPi version/model are you using?

[NoozAbooz]

I'm currently using a RPI 4 8gb ram with a memory split of 256

[torralbaalla]

Hmm... I have a RPi 4 with 4 GiB RAM, and the only way I got rid of that error was setting the GPU memory to 128 MiB and the GL driver to GL (Fake KMS).

[NoozAbooz]

Hm. I set the openGL driver to fake kms and also set gpu_mem to 128mb, but it's still going me the error.

[torralbaalla]

Sorry for the (maybe dumb) question but, did you reboot?

[NoozAbooz]

Yes

[torralbaalla]

Hmm... No idea, maybe you could ask in the RPi forums? Because the last thread on the topic is very, very, very old.

[NoozAbooz]

Hmm ok. mcpil does have https://github.com/xobs/mcrpi-wrapper right?

[torralbaalla]

Sort of, it currently uses the mcpi-docker libcompat.

[torralbaalla]

@mobilegmyt Try by using using GL Legacy, I tried and MCPI runs with that config in my RPi 4.

[NoozAbooz]

How do I switch to that?

[torralbaalla]

Via raspi-config:

# Launch it
sudo raspi-config

Go to Advanced Options->GL Driver, and then select Legacy, reboot if it asks you to do so.

[NoozAbooz]

Ok, so I did that, but I got the error [ERR]: GLFW Error: X11: RandR gamma ramp support seems brokenminecraft-pi: /build/glfw3-UExs5r/glfw3-3.2.1/src/input.c:153: glfwGetInputMode: Assertion `window != NULL' failed.

[torralbaalla]

That error sounds familiar, let me check the Discord server (by the way, join us if the total lack of privacy does not concern you! 😉).

[torralbaalla]

Yes, someone already reported it in the Discord server, just opened an issue (#8) to track it. By the way, I'm closing this issue as resolved tomorrow, if it does not get any activity.

[torralbaalla]

Closing...
