> run top, and look at the load averages at the top right. (number of tasks waiting running/waiting to run averaged over the last 5/10/15 minutes). Gives you something like 0.22, 0.32, 0.32. > Is your CPU idling at low speed, like it should be?

Is set to "ondemand". > Core 2 CPUs have a built-in temp sensor that reports a relative temp, relative to the max temp. > do grep . -n /sys/devices/platform/coretemp.0/temp1_* Gives you /sys/devices/platform/coretemp.0/temp1_crit:1:100000 /sys/devices/platform/coretemp.0/temp1_crit_alarm:1:0 /sys/devices/platform/coretemp.0/temp1_input:1:66000 /sys/devices/platform/coretemp.0/temp1_label:1:Core 0 /sys/devices/platform/coretemp.0/temp1_max:1:100000 Not that I would know what tht means. Why doesn't someone should build a simple GUI tool for all temperature related issues which makes checking temperatures easy? At least I managed to install the GNOME Sensors Applet, and it tells me that my HDD is on 45 degrees Celsius, which seems far too much to me. Maybe it gets overheated because the CPU heats everything up so much. Unfortunately I didn't get the GNOME Sensors Applet to tell me more about CPU temperatures. Sorry I have to shut down the computer and let it cool for half an hour now anyway. -- WARNING: Intrepid might burn down MacBook Pro https://bugs.launchpad.net/bugs/262550 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
