: The log now shows that ForceLowPowerMode was used to set the clock at 100000 Mhz. The heat is reduced, but not by as much as I had hoped. Originally I had tried to set "LowPowerModeEngineClock" "50000", but when X started, the screen was wildly distorted and "stretched?" so that the kdm login was at the far right side of the screen.
Can I just pick a number that isn't a direct multiple/factor of the full power clock of say 70000?
Any sensible value should work. The algorithm in AtomBIOS seems to automatically adjust it to a nearby possible value if the exact specified clock can't be achieved.

Yang, Here is a final bit of follow-up on this thread. In summary fashion: "LowPowerModeEngineClock" "50000" X would start, but was unreadable with all information pushed off the right side of the display; "LowPowerModeEngineClock" "100000" X starts and works fine with kdm. Heat load and fan noise were reduced, but not by very much. Notable slowness on compiz-fusion splash on compiz start and cube rotate. Laptop palmrest still uncomfortably warm compared to fglrx driver. "LowPowerModeEngineClock" "200000" Heat load and fan noise increased, no perceptible slowness in compiz splash but slow cube rotation compared to full clock of 400000. Thank you for all your help. I am now set up to test the radeonhd driver and I'm happy to do it. As mentioned before, if I can send or post anything else, just let me know. I have posted the latest Xorg.0.log at: http://www.3111skyline.com/download/linux/radeonhd/downclock/Xorg.0.log.2022... Great driver and much needed now with the fglrx driver going away for so many users. -- David C. Rankin, J.D.,P.E.
