I have a white screen (Chrome OS/Debian KVM)

[Christiaannr1]

I have a white screen i dont know why

[ds58]

What operating system are you using? Are you sure you removed the old version of MCEF?

[Christiaannr1]

Im using Linux Debian on chromebook. Yes i removed the old version of MCEF

[ds58]

What CPU does your Chromebook use? Is it ARM based?

[Christiaannr1]

Im going to check

[Christiaannr1]

AMD64 i think

[ds58]

Are you using the vanilla launcher or a 3rd party one?

[Christiaannr1]

I first tested it with multimc but that didnt work so i tested it with the vanilla launcher and that also didnt work

[ds58]

Could you post the output of lscpu and also lspci?

[Christiaannr1]

Uh where can i find that in .minecraft?

[ds58]

You will have to run those commands in a terminal shell

Are you using a KVM virtual machine? Does your GPU have 3D acceleration? Its listed as a virtio GPU

[Christiaannr1]

I dont know. Where can i find it?

[Christiaannr1]

Do you mean this?

00:09.0 Display controller: Red Hat, Inc Virtio GPU (rev 01)

[ds58]

The info in lscpu and lspci leads me to believe you are running a virtual machine. Is this the case?

[ds58]

Do you mean this?

00:09.0 Display controller: Red Hat, Inc Virtio GPU (rev 01)

Yes also: Hypervisor vendor: KVM

[Christiaannr1]

When you enable linux in chrome os it makes a virtual machine to run linux apps and use the terminal

[ds58]

I wouldn't be able to support this setup unfortunately. Are you even able to play Minecraft?

[Christiaannr1]

Yes with 50-60 fps

[ds58]

Could you possibly post a tutorial you followed to get this working? Not super familiar with Chromebooks or Chrome OS

[Christiaannr1]

I have not followed a tutorial. I just downloaded forge for 1.12.2 and then webdisplay mod and MCEF but then it didn't work so I looked on the internet and saw this mod you made and wanted to test it only it was still white screen. Sorry if my english is bad.

[ds58]

Sorry, I don't think I can support this setup. I don't have access to a Chromebook nor do I believe it would work in a virtualized environment using virtio GPU drivers (which to my knowledge don't support opengl? at least not without major tweaks)

It may be possible to get it working with some tweaks but you'll have to be on your own.

Currently, MCEF supports (on native hardware, not virtualized):

Linux x64 Windows 10 x64 macOS x64

[Christiaannr1]

Aw man I wanted to do this mod with my friends
