Hello,

I try to install the graphic acceleration with Ubuntu 9.04 on a system which has the same configuration (Intel Atom + Poulsbo).

I have installed the differents lib and bin :
- Kernel DRM module (psb.ko)
- GPU firmware (msvdx_fw.bin)
- Xorg driver (psb_drv.so)
- Xorg driver binary blob (Xpsb.so)
- DRI interface (dri_psb.so)
- Hardware video decode interface (psb_drv_video.so)
- Valib aka vaapi (libva.so)
- libDRM (libdrm.so)

This is the result of glxinfo :

I think I have a problem with the function drmWaitVBlank.
If someone has the solution to repair this function, I want it.

Thanks, nicolas
