This blog post isn’t only directed to ThinkPad owners as most notebook Linux users with Intel Core Duo 1/2 and i3/i5/i7 processors have been affected by this bug if not all. And yes, this problem is present on latest Debian Unstable and Ubuntu 11.10.
I’m owner of Thinkpad X300, great machine except the fact that just recently I replaced its 3rd cooling fan! Yea, I do a lot of compiling and it’s on all the time, but still this kind of things shouldn’t happen. I first linked this problem to the fact that Thinkpad fan on Linux (as of 2.6.22) always works at what’s its basically maximum RPM, thus the reason there are numerous fan control scripts. My favorite one is Thinkfan, but controlling fan doesn’t really help if you have a overheating problem. For matter of a fact it working on its maximum speed might only help, with its own toll.
As of kernel 2.6.38 up until 3.1 (still present) there has been a problem of power regression but besides this I had slight problem with overheating. Regarding overheating in beginning I tried reporting bugs, tried different Thinkfan configurations, blamed proprietary software such as Adobe Flash for spiking up CPU temperature, however this problem was somewhat solved. After numerous battery calibrations and as these didn’t work in the end for battery life getting poorer with each day, I just blamed the factor that notebook was getting pretty old (~3 years).

Debian 5.0 Lenny was released on 14th this month. 22 months of development, I knew the exact release date long time upfront, but I didn’t plan that right on that day FoolControl will go through some downtime :/
Nevertheless, Lenny is out, and out of sudden I don’t have much stuff left to talk about on this very topic now :) I find Lenny to be one of the best releases Debian releases yet, I too contributed to this release as much as I could. Didin’t make into package maintainers, but it’s all matter of free time, and dedication really.
I’ve been with Lenny, well pretty much since Etch was released, I moved to Lenny. Since Lenny is stable now, and new testing is Squeeze, don’t jump on Squeeze right about now, since there aren’t security updates at the moment, since security team for Squeeze isn’t formed yet.
However, Lenny has been great for very long time, and I’d really enjoying sticking to it, but I believe I’ll move to next testing in no time, life on stable … it’s boring :)

I’m spending this lovely Saturday morning to go through some bugs in Debian. Actually I set my eye on one special bug, Lenny RC bug which in few days will be 1 year old, and then this fact and figure as one ripped the stitches of my mouth, and thus I started writing this post … I want to talk few things over in general Linux development and possibly give definition to this highly cryptic title.
EXA vs XAA on i965
But before that let me tell you a little story that should’ve been told long time ago. When I got my x300, I was “thrown” on a lot of new stuff. One of the most interesting things is that i965 was blacklisted in Compiz (and as I see it now, it still is). So as I configured everything back in the day, last step was to configure Compiz. I was very surprised to see i965 to be blacklisted, nevertheless this was none of the problems that will follow.
EXA is default, EXA is supposed to replace XAA, so here’s the paradox. With that same default EXA you’ll run into numerous problems, from basic scrolling being slow, to whole compiz being incredibly slow, to the point of not being usable. Of course you can spend hours and hours tweaking and hacking to make it run any faster, maybe fix scrolling speed, you’ll make it, but the I believe the “core” of this problem is in something else. Also there is a good side to side of this story, you can play videos, however if you run them in fullscreen they’ll go just incredibly slow, no matter really what plugin you set as your video playback.
Setting video playback plugin to “No XV” didn’t do anything, neither did Xshm or any other option. But then I said, hold on, why is i965 in Compiz blacklist again?

Well, I had stories with beryl/compiz 3g desktop in general, just go on and search blog if you wanna. Anyways, last time I used compiz-fusion was sometime in late October 2007, I was just devastated with its bugs, so I removed it. Same happened with all of my previous 3d desktop experience.
This was performed on Debian Lenny/Testing, KDE 3.5.8, 126.96.36.199 on Intel 945GM
So I installed it yesterday, my first impression was … well this is getting better. I mean I just had feeling that it just wont crash and explode :) That’s the kind of feeling I had before. Many bugs were fixed, but still … there was a lot of … well problems. Which I’m just too lazy to go over right now. Since compiz-fusion is in Debian Lenny/testing respiratory, that’s the one I was using, anyways, this is what I suggest.
Use “shames” compiz-fusion resp, I also tried his “unstable” compiz-fusion resp, but it was just too much for me, but the one from testing … absolutely beautiful. So add his resp. to your sources.list
