Mesa: glxgears crashes on 32bit ARM devices

[Yisus7u7]

Problem description

The window comes out for a few seconds and then disappears

Info: Android 8.0 32 bits 2GB of ram DE: lxqt WM: Openbox Using vnc

In proot it works, but in termux anything related to OpenGL does not want to work

Steps to reproduce

Expected behavior

[Yisus7u7]

@xeffyr Posh Shell (armhf alpine, proot) has no problem running openGL, so the error will be that any specific hardware/driver cannot be accessed?

[Yisus7u7]

Apparently Xephyr and Posh Shell have no problem with openGL apart from its very poor performance.

Note that both use wayland

@xeffyr Solved! Turn on mesa hardware acceleration

Enabling on mesa hardware acceleration

[Yisus7u7]

The performance is excellent, there is no lag, everything goes very fast

[sukualam]

The performance is excellent, there is no lag, everything goes very fast

Does it run on debian proot/chroot?

Does it run on debian proot/chroot?

No, it is fully native in termux x11

this is currently using the llvmpipe driver unless you specified GALLIUM_DRIVER=zink

[sukualam]

Actually its better to run in chroot linux because it hss many 3D app/games , also box86 wine.. But if it still in termux desktop, i think there is no app/games there..

[DLC01]

this was using the Zink driver

[sukualam]

this was using the Zink driver

Can it work on Adreno 506?

[DLC01]

this was using the Zink driver

Can it work on Adreno 506?

it should work on all GPUs that support vulkan

[sukualam]

Can it work on Adreno 506?

it should work on all GPUs that support vulkan

Can you give me tutorial link? I tried few days ago, i read tutorial somewhere, but in the end, i compile and not work.. Is it like turnip? do you have tutorial?

I will try in chroot..

you could try the instructions in https://github.com/suhan-paradkar/tewmux-disabled/releases/download/mesa-hw/instructions.tar.gz

i dont know weather it will work in an chroot envionment

[Dawimpy]

You can try this in chroot environment

ok i couldn't get it to work ... i'll ask you in telegram ... please respond me there

@xeffyr @suhan-paradkar

I just killed two birds with one stone

1 - OpenGL crash in 32 bits arm devices

How to fix it?

• Enable opengl in mesa, vulkan drivers and galium drivers.

• I haven't tried zink, but you don't need to enable zink

• Add wayland, libsha1 mesa-gl, mesa-dri packages

• Enable opengl in libepoxy package

• Enable opengl, Xephyr, dri1 dri2 dri3, in xorg-xserver

And voila!, everything will work smoothly in both Xwayland and vnc.

2 - How to fix gl4es is slow

Just follow the steps in step 1, and voila, gl4es will go fast and smooth.

Additional Notes

Do not use ndk-multilib for compilation, leave OpenGL broken for compilation of more packages in the future

It works perfectly, I don't get segmentation failures and the optimization is excellent, I don't know if this works also in 64 bits.

The slowness of gl4es must be because the graphics are forced, since mesa does not provide a correct rendering, I think that explains why gl4es is slow

I was guided by this page :

https://gxmersam.blogspot.com/p/getting-hardware-acceleration-on-termux.html?m=1

And I go back and repeat, I'm not using zink, you don't need zink to work.

I hope you find all this information useful

[DLC01]

from what i have seen before mesa has some issues when compiling in ci, mainly saying llvm-config not found

@Yonle

Please do not mention me as i'm not interested with this. I repeat, do not mention random user.

[AbdullahBinJahed]

a little help ? i just can't seem to get it work 😥

[Yisus7u7]

Sorry I mentioned it by mistake

[ghost]

Lots of off-topic and overquoting.

I'm locking issue now. If you know how to fix - submit a pull request with changes to package versions, build configuration and patches (whatever is required).

[xtkoba]

Note that mesa-demos, the package that contains glxgears, has been disabled now. This issue is not worth being open.
