Hey everybody!
I am having overheating issues with an old thinkpad and having done some research have drawn up three potential partial solutions:
1) Wait for the next Ubuntu release, apparently 2.6.35 has super duper Radeon GPU (my hot graphics card) power saving features.
2) Patch existing kernel with linux-phc (http://www.linux-phc.org/forum/index.php) to undervolt system (requires recompiling the whole kernel)
3) Hardware mod. Glue in a thermal sink. This is reported to work fairly well.
Anyway, my idea is to combine solutions 1 and 2 and wait till the stable release of 2.6.35, patch it with linux-phc (http://www.linux-phc.org/forum/index.php) and install that on Lucid.
Since I am recompiling and reinstalling the kernel anyway, I may as well grab the latest and greatest and enjoy the benefit of the extra power saving features.
My questions are:
- IS THIS MADNESS?? If I am compiling my own kernel either way, is it a good idea to go ahead and grab the latest kernel instead of 2.6.32?
- If I am compiling my own kernel anyway, would the cautious use of a couple of architecture specific CFLAGS be a safe thing to do? Getting that bit of extra performance on an ageing laptop would be super.
