glxgears gives errors on newly installed ATI drivers

Hi all...I finally managed to install the 8.34.8 ATI fglrx driver on kernel after much frustration and a patch. So glxinfo gives me direct rendering finally and all would seem well except for this. When I run glxgears it prints a series of lines that all say the following:
FGLTexMgr: open of shared memory object failed (Permission denied)
__FGLTexMgrCreateObject: __FGLTexMgrSHMmalloc failed!!!
and then it runs seemingly okay. What do those errors mean? How and what do I give permission to so that this error doesn't occur?

I believe that the newer ATI drivers mess up glxgears ... don't use glxgears for that. I've heard ATI has their own version of glxgears that works ok.

Two things to try.

1) In your fstab file add the following line:
tmpfs /dev/shm tmpfs defaults 0 0

2) in your xorg.conf
add this at the bottom:

Section "DRI"
Group 0
Mode 0666

Reboot and see what glxgears gives you then.
