[Solved] (Partial) Loss of vid acceleration with xorg 1.7 & nvidia 190

Question

I've noticed people having a lot of problems with the new xorg server crashing, but my problem appears to be different:  Xorg is stable, hasn't crashed yet: but games (and steam) fail to load.  However, video acceleration works just fine for compiz and glxgears. 
The games are run in a 32 bit chroot, which is completely up-to-date. I haven't seen anyone else with this problem, so I'm creating a new post (whith a topic title that may be way off :).
Here are the error messages displayed when I try to load the games:
Quake4:

Make sure that your X server is running and that $DISPLAY is set correctly.

I've posted on the tail end of the output for Quake4 and ET:Quake Wars for brevity, but included it all for Steam.  I've lost the old xorg and nvidia packages, so I'm unable to downgrade.  Also, "echo $DISPLAY" in both native and 32bit chroot terminal's output :0.0.
Am I missing something obvious here?  Anyone else experiencing something similar?

Answer 1

The problem was because of the 32 bit chroot: X server wasn't allowing access.
"xhost +local:" run from the terminal before trying the games fixes it (but needs to be done with every reboot).
Now, I just need to figure out what's changed seeing as I never had to do this before... (schroot?, Xorg?, ??)
