@Julian Thanks for the help. This was the cause of the power difference. Adding i915.i915_enable_rc6=1
to the kernel parameters at /etc/default/grub.cfg brought back the good power consumption level with the latest kernel image. I hope the Intel Devs sort out the rest of the problems so this could be enabled by default. This really makes a difference with laptops. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/818830 Title: Serious power regression from kernel 3.0.0-6 to 3.0.0-7 (30% more power at idle) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/818830/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
