Hello,

Power management has drastically improved in recent kernel/Ubuntu development. I was wondering if these suggested kernel power saving tweaks are still needed.

GRUB Kernel Line

i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 drm.vblankoffdelay=1

ALPM

echo SATA_ALPM_ENABLE=true | sudo tee /etc/pm/config.d/sata_alpm

Reduce Wakeup Events

gconftool-2 --type string --set /apps/gnome-terminal/profiles/Default/cursor_blink_mode off

Thanks.

Seems to default to false according to /usr/lib/pm-utils/power.d/sata_alpm.

Still blinking (and I'll keep it that way).
