Pas d'acceleration graphique Intel GMA 900 [resolu]

Bonjour
Depuis que j’ai réinstallé ma debian testing je n’arrive plus à avoir accélération graphique

[code]debian:/home/damien# glxinfo | grep "direct rendering"
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)

[/code]

ddebian:/home/damien# LIBGL_DEBUG=verbose glxgears libGL: XF86DRIGetClientDriverName: 1.8.0 i915 (screen 0) libGL: OpenDriver: trying /usr/lib/dri/i915_dri.so libGL error: dlopen /usr/lib/dri/i915_dri.so failed (/usr/lib/dri/i915_dri.so: cannot open shared object file: No such file or directory) libGL error: unable to load driver: i915_dri.so 874 frames in 5.5 seconds = 158.393 FPS X connection to :0.0 broken (explicit kill or server shutdown).
