Hi, I moved away from Ubuntu because of all the grief with bugs, regressions, poor hardware support, and all the yearlong unsolved bug reports. I don't blame anyone for this. I know Ubuntu is free software. But for me personally I can't comment any more as I am not using Ubuntu at the moment.
~ Kwinz -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pm-utils in Ubuntu. https://bugs.launchpad.net/bugs/459967 Title: scripts called on ac power or battery power fail (power.d) Status in acpid: New Status in Laptop Mode Tools: Invalid Status in “pm-utils” package in Ubuntu: Invalid Bug description: Binary package hint: pm-utils I want a script to be executed when my laptop is connected to AC and another one when it runs on battery. For the beginning it should just do On AC: echo max_performance | tee /sys/class/scsi_host/host0/link_power_management_policy On battery: echo min_power | tee /sys/class/scsi_host/host0/link_power_management_policy I decided to create two scripts in /etc/laptop-mode/batt-stop/ and /etc/laptop-mode/batt-start but they where sometimes executed and sometimes not. I thought this is strange, maybe laptop-mode-tools is buggy and I investigated an alternative approach. There are two files in /etc/acpi/events/ : ac and battery both call /etc/acpi/power.sh which in return calls pm-powersave man powersave tells me there are two directories /usr/lib/pm-utils/power.d/ and /etc/pm/power.d/ the later has priority but was empty on my installation, so I went to /usr/lib/pm-utils/power.d/ I created my own file here, called my-powersave /usr/lib/pm-utils/power.d/ lsl total 28K drwxr-xr-x 2 root root 4,0K 2009-10-24 20:34 . drwxr-xr-x 6 root root 4,0K 2009-10-21 05:34 .. -rwxr-xr-x 1 root root 1,4K 2009-10-06 23:41 95hdparm-apm -rwxr-xr-x 1 root root 646 2009-09-17 21:33 anacron -rwxr-xr-x 1 root root 293 2009-10-07 01:02 laptop-mode -rwxr-xr-x 1 root root 248 2009-10-24 20:36 my-powersave -rwxr-xr-x 1 root root 693 2009-10-06 23:41 sched-powersave This worked, BUT again the sata link sometimes stayed at max_performance in battery power. It worked most of the time if you have not done anything when removing the power and it hardly ever worked when you disconnect and reconnect in short 5 second intervals. I think there is an underlying bug in pm-utils or acpi. I would happily provide needed logfiles or debug output if you tell me which.
