for direct rendering in gazebo have a look on the following:
http://playerstage.sourceforge.net/doc/Gazebo-manual-0.5-html/gazebo_opengl.html

in your case it must be commented out the glx module in 
/etc/X11/xorg.conf or xfree config file.

hmmm, i am getting same error messages similar to yours and this is on 
an nvidia machine which i tested. i suspect it has to do with the 
version of wxPython you installed. i remember reading in the email list 
that compatible is version 2.4. anything more recent than that has issues.
