The problem I've been having is that every time I either hold or look at either the track blueprint or a train, the screen turns blue. It's a lighter shade than the sky so its most likely not a chunk loading issue. I am still able to pause the game but no menu pops up. I've tried troubleshooting it and nothing works.

Okay, I made sure that Java is using the NVIDIA card. It's still doing it...

can you send the "latest.log" file?

Wait, It turns blue when I hold the blueprint. But when I look at stuff its fine. So that a start. I"ll try and get you the log file.

Here's the log. Idk if it will be much help but here it is.
Its late where i'm at right now so this is my last comment for the night.

That light blue indicates an OpenGL Error. What graphics are you running?

Graphics card

what do you mean?

are you talking about my computer itself or in game?

computer...

NVIDIA Geforce GTX 770m
Intel HD Graphics 4600

have you set the java executable to use the NVIDIA card?

I'll Double check

It's still using your Intel card.

Also props for using Ubuntu 👍

If you go into your BIOS you can disable the Intel graphics.

Now I have another problem, now my Minecraft won’t open. Every time I try to open immersive railroading, it just crashes before I even got to the Mojang screen

Says that the driver doesn’t support OpenGL

Alright I updated the Nvidia drivers, it makes it past the launcher but now the problem is that when it gets to the mojang screen it stops responding, but it’s not OpenGL. So I’ll see what I can do.

Alright! I finally got it working!! Thank you all so much for your help!

You will need to update your nvidia driver
