I've been setting up power management on my HP compaq laptop using this article, http://www.gentoo.org/doc/en/power-management-guide.xml, as a reference.
Just a couple of questions I thought I'd ask. (1). CONFIG_ACPI_VIDEO seems to be missing in the 3.10.17-gentoo kernel, but is available in 3.10.7-r1. for f in /usr/src/*/.config; do echo $f; grep CONFIG_ACPI_VIDEO $f || echo $?; done /usr/src/linux-3.10.17-gentoo/.config 1 /usr/src/linux-3.10.7-gentoo-r1/.config CONFIG_ACPI_VIDEO=y /usr/src/linux/.config 1 (2). I've got my current kernel set up to use the 'userspace' governor by default. grep ^CONFIG_CPU_FREQ_DEFAULT_GOV .config CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y The settings below were set to use 'ondemand' by default, so I changed them to 'userspace' to correspond to the kernel setting above. Is that right, or should I have left it set to the original value, or set it to something else? /etc/laptop-mode/conf.d/cpufreq.conf s/ondemand/userspace/ LM_AC_CPU_GOVERNOR=userspace s/ondemand/userspace/ NOLM_AC_CPU_GOVERNOR=userspace Thanks.
