ATI Only root run, solved

I'm pissed of about this problem,
today i decided to solve it.
I assume you are using ATI official drivers, and you have installed them yet.
Looking on the web I found a lot of infos...
1) Check your xorg.conf for:

Section "DRI"
  Mode 0666
EndSection

if not present add it.

2) Check your fstab.
cause running an fglx apps I got

Using GLX_SGIX_pbuffer
FGLTexMgr: open of shared memory object failed (Permission denied)
__FGLTexMgrCreateObject: __FGLTexMgrSHMmalloc failed!!!
FGLTexMgr: open of shared memory object failed (Permission denied)
__FGLTexMgrCreateObject: __FGLTexMgrSHMmalloc failed!!!
FGLTexMgr: open of shared memory object failed (Permission denied)
__FGLTexMgrCreateObject: __FGLTexMgrSHMmalloc failed!!!
FGLTexMgr: open of shared memory object failed (Permission denied)
__FGLTexMgrCreateObject: __FGLTexMgrSHMmalloc failed!!!
FGLTexMgr: open of shared memory object failed (Permission denied)

so....
add this
tmpfs /dev/shm tmpfs defaults 0 0
