I am considering to try what is mentioned here - Battery life decreased after upgrade to 11.04 - concerning minimizing power consumption.
For example I see that in my case - i915.i915_enable_rc6=0 by issuing the following command cat /sys/module/i915/parameters/i915_enable_rc6 .
Would it be possible to switch it to 1 after booting?
If yes, how can we do that?
