Hi all, I'm having a bit of an issue with powermizer. The other day I realized powermizer was completely not working (at least not the way I want it to, not sure it worked in the first place). The video card seems to be "stuck" in performance mode. After reading up on several things including the arch nvidia wiki. I discovered I could force the clocks down to power save, which is good, but I would prefer adaptive, or at least something like: plugged in performance, on battery power save. I know it specifically states how to do this in the wiki, but it doesn't work for me. The clock speeds change only on the PowerMizerLevelAC settings, no matter if I am on battery or not. Whats more is the nvidia drivers only seem to be able to detect that the acpi state has changed after restarting xorg server, as in it's fixed to AC or Battery until the server restarts.
I don't know whether it's a problem with my xorg conf or I'm just missing something from some lack of sleep or noob related issues. So I included the relevant parts of my xorg conf. Note, I am on a laptop with an 8600m, up to date driver, i use dual monitors with twin view,acpi is installed correctly.

Hi MattSmith,
There is my xorg.conf and I have no option about PowerMizer at "Device" section. The PowerMizer runs properly on my pc.

Hi, sorry for reviving this thread, but I've just found that the PowerMizer doesn't work (at least for me) in TwinView configuration. Tested with 270.41.19 and 275.09-beta on nVidia GT218 [NVS 2100M]

Sorry to say, the only settings that worked for me was forcing the level, I have not been able to get PowerMizer working correctly in adaptive mode.
