But will remain with Mint 11 until the kernel is out probably.
Now, having edited grub for my resolution (no success though) I'm more confident. I couldn't get my head round the edits when you first mentioned them to me. I run my Thinkpad X220 since some time like this and it needs only 5 W when idling, giving me 5 to 8 hours on battery. If it works as expected and no system instablity occurs (there's only a small risk) then make these changes permanent:įind the line with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" and insert the above mentioned parameters. so here we go:Īt the grub menu press and navigate to the line with splash (or nosplash) and insert pcie_aspm=force and i915.i915_enable_rc6=1
Just yesterday I guided a mate over in the german section and he was very happy about the solution. (just search my postings) I even told ddaann how to cure it but he didn't hear. But I'm somewhat tired now repeating this over and over like a mantra. It's easy to revert these changes and to carry out a test. These changes came with kernel 2.6.38 and 3.0. If it's a sandy bridge with hd graphics it's dead shure you are affected by the 2 power regressions that were introduced by changing the allowed CPU/GPU/chipset power states due to bug reports.
