Re: Direct Rendering not working on my system

Hi,
I am using a Compaq Presario System. 

Don't know this machine
It has a 915 Chipset. 

.. or the chipset..
Direct rendering is not working on my system, even though it was working earlier when I had Fedore Core 3 installed on my system.
good news.. so it's possible to get it to work.. not everyone is that lucky..!
what is installed *now* would probably also be of some interest.. xfree..? xorg..? version...??
Here is the output of glxinfo. Could some one tell me whats wrong with my configuration, or how can I get direct rendering to work.

shot in the dark.. a common cause of X disabling dri is lack of video memory.. all things equal it could be that your former install (FC3) defaulted to a visual depth of 16 - rather than the depth of 24 advertised by glxinfo..
since this can be easily verified I would specify a "DefaultDepth 16" the X config file and restart X.. see if that makes any difference.. (in any event when you do get dri to work it will provide better performance..)
otherwise it could be that this "915" is one of those integrated chips that shares the system's ram and that for some reason the X server you are running does not recognize this shared memory.. in this event the above suggestion might not make any difference.. but there might be a patched driver lying somewhere that recognizes the shared memory and that FC3 installs while your current distro doesn't.. may want to google for that..
