[SOLVED] Intel 4000 HD: 3D acceleration?

Hi guys! I just installed arch linux on my HP Sleekbook, which has a Intel 4000 HD GPU.
I've installed xf86-video-intel, intel-dri, libva-intel-driver and lib32-intel-dri. I also edited /etc/X11/xorg.conf.d/20-intel.con and added the tear free configuration.
From KDE System Settings, I chose OpenGL 3.1 Native. The UI runs quite smootly, but KInfoCenter says that I've no 3D acceleration.
My question is whether it's normal or not. If not, what should I do?

Anything interesting in X logs and systemd's journal?
I assume /etc/X11/xorg.conf.d/20-intel.con is a type - it's missing 'f' at the end.

Yep, it's a typo, sorry for that.
Can't find any problem:

Xorg log
20-intel.conf
Journalctl log

What happens if you use kwin_gles --replace? I think I remember reading somewhere before that kwin + opengl 3 is messed up on intel, but if you use gles it works. Was a while ago, I may be completely wrong.

Still "unknown" 3D acceleration

Re: [SOLVED] Intel 4000 HD: 3D acceleration?

Well, rather funny, just took a better look at your screenshot. Notice that blue glow around the window? That's a window shadow which would not be there if kwin effects are not working.

Actaually, on that same screenshot, it says 3D Accelerator: unknown not 3D Acceleration: unknown. It just can't reconise the model name of the graphics chip.

If you want t confirm your 3d accel is working, just run:

glxinfo|grep direct

If it says "yes", you're good no matter what Kinfocenter is thinking it knows or doesn't.

I can confirm that it says yes! I assume that the Intel 4000 HD is correctly configured. In fact, KDE effects are smooth and good loking (thanks to tearfree configuration).

Thank you for your support man!
