I start working with OpenGLES using mesa on ubuntu 12.04 and when I run any program this message appears:
<message>
libEGL warning: DRI2: failed to authenticate
libEGL warning: DRI2: failed to open swrast (search paths /usr/lib/fglrx/dri:/usr/lib32/fglrx/dri)
</message>
If the program is runned as root onle the first warning is displayed. I run eglinfo (download from http://pastebin.com/Vnje5sEe and then gcc -o eglinfo eglinfo.c -lEGL -lGLESv2) and this is the output:
<output>

What am I missing?
Please your comments will be more than welcome.
