None of Intel's cards have thermal sensors, and their driver software is very basic. NVIDIA is the only company to provide accelerated drivers and utilities to non-Windows operating systems. You don't set the resolution with the utlity, that's why the XRandR extension was such an important milestone to accomplish when X.org 7.x was instituted on OpenSolaris. Again, the Intel cards lack the functionality. James
