DRM permissions fails [SOLVED]

When running glxgears i get the following error

libGL error: open DRM failed (Operation not permitted)
libGL error: reverting to (slow) indirect rendering

I have the following in my xorg.conf file

Section "DRI"
   Mode         0666
EndSection

I boot up using kdm and these permissions don't seem to go into effect until I forcefully reboot X windows with alt-ctrl-backspace. After I do this, I know longer get the error. Any suggestions to fix this?

I have:

Section "Module"
    Load        "dbe"   # Double buffer extension
    SubSection  "extmod"
         Option    "omit xfree86-dga"   # don't initialise the DGA extension
    EndSubSection

    Load        "type1"
    Load        "freetype"

    Load       "dri"
EndSection

Section "Device"
    Identifier  "915"
    Driver      "i915"
    VideoRam    4096
EndSection

Section "DRI"
    Mode 0666
EndSection

Re: DRM permissions fails [SOLVED]

Thanks, adding to the group video solved the problem. Using Driver "i915" gives me the error "Module not found".
