Public bug reported:
I have a power regression + over heating with my dell 7110c laptop
I have the tried following fixes :
pcie_aspm=force
i915.i915_enable_rc6=1
i915.i915_enable_fbc=1
i915.lvds_downclock=1
Much better results (the fan finally stop turning at lest for w while)
but it is not comparable to windows(battery life time and fun noise)
I noticed that (with psense) temperature takes only 2 values : 44°c (fan
off) 55°c (fan on).
this is my first bug report, please tell me if I made any thing wrong
thank you .
