Window rendering problem on setBfree and Shuriken

[paul]

Hello.

On my laptop (Thinkpad T440s with KXStudio 14.04) the programs setBfree and Shuriken are just black rectangles. They seem to work for the rest, but they are impossible to use as everything is invisible.

What may be the problem, and why those two? Are they using some particular libraries that I may be missing?

Thanks!

So, I reckon the problem may have to do with OpenGL.
Is there any non-3D version of the UI available somewhere?

From the output below I guessed I had to install all the libtxc-dxtn, but the output stayed the same...any ideas?

There's an environment variable to run mesa GL stuff in software mode, that might help.

Code: Select all

env LIBGL_ALWAYS_SOFTWARE=1 setBfreeUI

I love you! It's finally working!!

What exactly is going on, though?

[paul]

What exactly is going on, though?

Your video card or drivers don't support the features setBfree needs.
Using that variable makes the openGL stuff run in the CPU instead of the video card. (which is often slower)

Yeah, exactly, I do not have a dedicated GPU. Is there a way to tell my system to do so always?

Yeah, exactly, I do not have a dedicated GPU. Is there a way to tell my system to do so always?

Yes, add this line to the end of your ~/.bashrc file:

Code: Select all

export LIBGL_ALWAYS_SOFTWARE=1

Next time you login all OpenGL calls will be done in software.

Ok thank you so much!
