How to get cube animation in KDE?

Got no clue what you have installed but if you don’t have optimus you do not need bumblebee. It is used to switch context (hardware wise) between the two GPU’s in a Optimus system. If you don’t have an Optimus system you don’t need Bumblebee and I have no idea what it may or may not do, it is certainly NOT helping anything.

I’m not particularly worried about unneccessary software on my machine. What I would quite like is ideas about why I can’t set Qt graphicssystem to “raster”. This would suggest there is something missing, which is potentially far more problematic.

Well, but Bumblebee maybe could interfere with the nvidia driver working correctly on your non-Optimus hardware.
No idea whether it does though.

This should not happen.

Can you try with a new user?
Maybe some wrong setting in kwin’s configuration is causing this.

I tried with another user:

  1. It was already set to Raster. “Funny” I thought

  2. I changed it to native. No problem. So I changed it back to Raster. Again, no problem.

  3. So I came back to my main account. It was set to Raster, from when it had told me it couldn’t change this. I changed it to Native and got an error message. So I changed it back to Raster. I gave me no error message. So I changed it back to Native. No error message. So I chnaged it to Raster again. And, once again, no error message.

So it says Raster. Hopefully it is Raster.

25

probably a messed up config file. Of course one user’s configs can not mess with another users configs. But logging out and back in may have reset a cache somewhere and changing back and forth may have corrected the config files problems.

just tried it out my self it seams the cube won’t work if your opengl is set at version 2, I needed to set it to ver 3.1 to get it to work it could be an nvidia issue, still I think compiz’s cube was better.

KWin’s cube works fine here with OpenGL 2, I’m using it since years.

I’m using the radeon driver though, with an old Radeon 9600 card which only supports OpenGL 2.1.
