Is there any documentation for how to do this? I've been poking around intel.com and have downloaded some datasheets, but nothing I've found describes how to use the actual graphics card. Maybe I'm trying to delve too deep anyways, since the DRM in the kernel probably abstracts this away. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
