Overheating in MacBook and Ubuntu Lucyd Lynx


Hi everyone, I hope you can help me with an issue (sorry if it's been discussed before, I did't find any thread): I have Ubuntu Lucyd Lynx in my MacBookPro5.1 and often it gets really hot. I found it is a common issue when installing Ubuntu in MacBooks, due to the OS-controlled chip for the CPU (at least I have read so).
I've been doing exhaustive searching in many sites, and found something that helped a little by updating some libraries, but it still gets quite hot.

Can anyone tell me something about it?

Thanks a lot,
David.

Hi, sorry for the delay. It's a 13-inch MacBookPro5,5 I got last year, and the fans are clean.
I've found some solutions that reduce to making the fans work at its maximum speed, and thus temperature decreases but with poorer battery efficiency. I don't think that decreasing temperature that way is a "solution", at least for me.
I've done almost everything that has been said about installing packages, updating, etc. but temperature stays about 70 celsius when no application is running, so you can imagine how hot it can get when you want to work...

@yooy: I'm afraid I don't understand what to do with the link... I can check temperature but that's something I already do. Could you explain it, please?

Thanks a lot

this comes from the webcam program cheese webcam booth
it may or may not help so write your settings down so you can set them back if needed
it has helped me

5.1. The video is sluggish/has a slow response. What can I do?


You may have set "ximagesink" ("X Window System (No Xv)") as video-output.
This means, that your cpu is doing all the work. Change it to "xvimagesink"
("X Window System (X11/XShm/Xv)") in order to let your graphics card do the work.



To change the settings, run "gstreamer-properties", click the Video tab
and change the appropriate settings.

5.2. I have a Mac with iSight and a ATI graphics card, and the colors are weird.


This is a problem with the ATI graphics card, though there is a work around.
Change the video-output to custom and insert the following: "ffmpegcolorspace !
video/x-raw-yuv,format=(fourcc)YV12 ! ffmpegcolorspace ! xvimagesink".



To change the settings, run "gstreamer-properties", click the Video tab
and select custom from the drop down menu.

cool did you mean runing cpu at 100% using distributed computing? I run distributed.net, even if i don't have any temprautures problem and my fans keep at high speed most of the time.

I mean set the fans speed to, lets say, 3000rpm even when it's not necessary or if CPU is at 2%.

Distributed computing is not a solution to me as my problem is in my MacBookPro and it's ussualy off at home. I use it for work, for traveling, and thus almost all the time with no conection to the internet.

Anyway, I'd rather a "real" configuration solution than an external "patch", but I'm starting to think that it would not be possible.

Thank you
