MInimizing power consumption of laptop with intel graphics
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?

You could try something like the following as root:
sudo -i
echo 1 > /sys/module/i915/parameters/i915_enable_rc6

You can also do:
sudo modinfo i915 | grep "i915_enable_rc6"
You would see this:
parm: i915_enable_rc6:Enable power-saving render C-state 6.
Different stages can be selected via bitmask values (0 = disable; 1 = enable rc6;
2 = enable deep rc6; 4 = enable deepest rc6).
For example, 3 would enable rc6 and deep rc6, and 7 would enable everything.
default: -1 (use per-chip default) (int)
I think that answers your question : )

You can also do:
sudo modinfo i915 | grep "i915_enable_rc6"
You would see this:
parm: i915_enable_rc6:Enable power-saving render C-state 6.
Different stages can be selected via bitmask values (0 = disable; 1 = enable rc6;
2 = enable deep rc6; 4 = enable deepest rc6).
For example, 3 would enable rc6 and deep rc6, and 7 would enable everything.
default: -1 (use per-chip default) (int)
I think that answers your question : )
