I'm trying to run a couple 3D games in Slackware 12, but there freeze very
often. Only the program freezes howerver. I noticed that if I run the
games as root, then the are fine and do not freeze.

So, it seems like root has access to something that my normal login name
doesn't. Any idea?

Do you have this section in your /etc/X11/xorg.conf?
Section "dri"
Mode 0666
EndSection

This area is designed to become quite warm during normal operation.

It wasn't there, so I added it and restarted X. It didn't make a
difference.

maybe the games need more precise timers, and otherwise deadlock ?!?
Try this
echo 1024 > /proc/sys/dev/rtc/max-user-freq

(a shot in the wild .. but)

That file is already set to 1024, so it doesn't work.

Thanks,

Start the program glxgears by typing that in a terminal and send the
messages you see there. Do the gears turn smoothly?

Also enter glxinfo in a terminal and send the output. Most important
line is "direct rendering: Yes"

VR

DRI is not enabled for some drivers - such as ati/radeon (the mach64 kernel module is
not present). So on these cards full 3D is not available in the stock slackware
kernel.

However, a more careful reading of the OP suggests a permission issue. If root can
run 3D apps fine but a normal user can't, then its unlikely a driver or Xorg issue.

The OP should check the logs (of any) to see if there is any kind of "access denied"
message. As a user, the game may be trying to write (or read) a file it doesn't have
access to. I have noticed that many linux games/ports installs seem to assume "root"
and do not set permissions correctly.

Native linux games. SuperTuxKart and Mania Drive. Also, Google Earth
freezes up in the same manor. Root can run them all just fine.
