that is fine for me actually since i don't ever see the need for one of the cores to by running faster than the other especially on a desktop system where micro-managing the procs/threads just isn't practical. since Mattia asked input from the users perspective, here's mine: i just got a new laptop which insisted on shutting itself down inexplicably. after some digging around, it turns out that the system was defaulting to "performance" governor (from within kde) and it seems that it ran itself too hot. i was compiling some c++ programs that i was working at the time and the opengl screensaver had kicked in - this was the first laptop that i had decent fps on so i figured some glmatrix would be cool. apparently, that caused the cpu to run at a 100% and made it too hot and therefore shut itself down - strictly my guess. after getting really irritated with a system randomly rebooting (i have a dual xeon server from IBM that's doing the same thing - albeit the VRM module seems to at fault there; unrelated but having to deal with multiple systems that randomly reboot is really frustrating); i decided to switch to "ondemand". the reason being that i want to run the CPU as slow as possible so as to not overheat but have the power when i'm compiling some programs. now, if the Duo falls under case two, as Dominik pointed out, i certainly wouldn't want one of the cores under the 'performance' governor running full tilt while the other is under 'ondemand' since that would ensure, as i understand it, the slower setting to be ignored and the whole thing runs at the higher speed setting of the two cores raising the temp too high. i'm going to test kde's acpi settings to see if it can 'ondemand' both cores. if not, i'm going to play around with cpufreqd init script and send some feedback. > > Dominik -- anoop aryal [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
