[Mesa-users] EGL DRI Driver Loading Error

[Srini]

[srini at RHEL2 ~]$ xdpyinfo |grep GLX
[srini at RHEL2 ~]$

Doesn't print anything.

[srini at RHEL2 ~]$ xdpyinfo |grep DRI2
    DRI2
[srini at RHEL2 ~]$

This prints DRI2.

I couldn't understand what it is significant for, can you please explain me?

can you please confirm me the configurationn i am doing is correct for enabling 
hardware acceleration?

Regards,
Srini.

This message means that either GLX or DRI2 extension is not available.
What does

  $ xdpyinfo | grep GLX
  $ xdpyinfo | grep DRI2

give on your machine?
