<br>
If it works as root, but not as a normal user, then there are two
likely possibilites: (a) they are using different OpenGL libraries
(libGL.so), or (b) a file/device permissions problem. And double
check that your DISPLAY environment variable is ":0". Also note
that most issues are solved by installing the proprietary AMD or
NVIDIA graphics driver (using the Additional Drivers dialog), so
if you aren't, do that first. My condolences if you have Intel
graphics -- in that case I'd recommend updating to Ubuntu 13.04
(or newer), the Intel Linux graphics driver is under heavy
development and the newer versions are much better.<br>
<br>
A quick test, run glxinfo (from the mesa-utils package), both as
root and as yourself. They should be the same, if not, then the
differences are a big clue.<br>
<br>
To test the OpenGL library hypothesis, run (CHIMERA is the path to
the Chimera installation):<br>
<br>
env LD_LIBRARY_PATH=CHIMERA/lib ldd CHIMERA/lib/_chimera.so<br>
<br>
both as root and as yourself. If they are not the same, figure
out why. If they are the same, then check the permissions on
every shared library listed.<br>
<br>
Please let me know what you try and if it fixes the bug,<br>
<br>
