how do I tell if I have direct rendering with no glxinfo

I've just switched from nouveau to the nvidia drivers because I was regularly getting a crash which a search suggested was due to nouveau.  Since doing that, however, glxinfo returns nothing.  No error, no info, nothing. glxgears the same.

Should I be using something else for nvidia?

My /etc/X11/xorg.conf.d/20-nvidia.conf looks like this:

Section "Device"
   Identifier     "Device0"
   Driver         "nvidia"
   VendorName     "NVIDIA Corporation"
EndSection

What's the output of

grep -i direct /var/log/Xorg.0.log

Re: how do I tell if I have direct rendering with no glxinfo

1) Did you make sure that the "nvidia" kernel module is loaded, but "nouveau" isn't? (Check the output of lsmod)

2) Did you make sure to remove any Nouveau related files/packages (nouveau-dri xf86-video-nouveau mesa-libgl)?
(If you always used pacman for installing drivers, this should already be taken care of.)

3) Did you make sure to remove any Nouveau related stuff from config files like /etc/mkinitcpio.conf and /etc/X11/xorg.conf.d/* ?

4) Does Xorg succesfully load the glx module? (Look for the string "glx" in /var/log/Xorg.0.log)

It's mesa-demos and I do have glxgears/glxinfo - they just don't seem to do anything...

Install xorg-xdriinfo and check if xdriinfo outputs something.
