Good bye my fellows...

[Oscar Pradilla]

i have to switch back, my MBP is too hot, i´ve able to run cooler but not as it needs, i´m not gonna risk it..

Also my video output crash, stop working, i´m tired of trying to make it run as i want so i will switch back to mac os...

i´m gonna miss this enviroment, i will try again with 8.1, let´s see what happen...

Has anyone tried mandriva gnome 2008?

Tks, and see you later..

Heat has been an issue how people on these machines. I do have to say that your Mac will turn itself off if it gets too hot.

Thanks for trying out Ubuntu though. You are likely to have the very same cooling / power performance in Mandriva (or any other distro) because they all use pretty much the same software to handle these things.

[spencercarran]

Is there any way of dealing with the heating issues? Mine usually isn't terrible, but it definitely runs appreciably hotter than it did under OSX.

[stream303]

I'm just thinking out loud here... :)

Does top reveal any cpu-hogging processes?

Although it has top in it's name, the following utility is NOT really dedicated to being a top replacement, but a power-saving utility from Intel: PowerTop. (it is in the normal download repos) Has anyone run that to help identify power-hogging issues and seeing if the recommendations make any improvements?

Any kernel gurus out there? Has anyone played with the ioscheduler to change the default from CFQ to something like NOOP, DEADLINE, etc and compared results? End-users can change this on the fly or in grub's menu.lst

.. I guess I have my propeller-hat on today. :)

[cyberdork33]

you can cool the machine down a bit by doing some power saving / performance changes as people have stated in other threads.

True enough - however I've found that Intel's powertop, which is in the download repos, can expose things that aren't normally seen, and offer suggestions to cut power use down further, such as VM Dirty Writeback times, etc.

It is definitely worth running to see what it finds. It will cycle through a few suggestions if you leave it running for about a minute. I think it would expecially useful to those who want to compile their own kernels, but you can change a few things from an end-user standpoint.

Note that you have to run powertop as root, ie sudo powertop. Fortunately, this isn't something you normally leave running except to just gather the initial information it provides.

well this is what i've donde and make it run between 30 - 40 C better than the last time

1. Install Powersaved
2. sudo gedit /etc/init.d/rc
3. Change then Concurrency=none for Concurrency=shell

It runs much better, but the video output....grrr..can't get it right, after installing with envyg i've got the white screen.... and can't make it work....


I'm gonna try other distro and i will tell you...if not...mac os again..

Well, OSX is a great operating system too, and I think if you really want to you can play around in the command line (it is derived from BSD, after all). You might want to experiment around with Solaris or FreeBSD if the heating is too big an issue; I don't have much experience here but I've heard that the heating tends to be a Linux thing.

[Oscar Pradilla]

Well i'm back on mac os, runs really good, but it' s not what i want...miss you ubuntu...lets hope that next one will be better

I will run ubuntu under virtual machine which one do you recomend?

1. VMfusion
2. Virtualbox
3. Parallels

TKS

I'm sorry to hear about the temperature problems the OP is having with his MBP -- the more so, since I know from experience that it can be very different.

For the record: I have a 15" 2.4GHz MBP 4,1 (Penryn) with 4GB RAM, on which I dual-boot Mac OS X and GNU/Linux (using the rEFIt boot manager). I've been experimenting a bit with versions of GNU/Linux, having used both Ubuntu Hardy 8.04 and Debian testing (with a smidgen of unstable) -- I've found very little difference between the two, especially since some of the Ubuntu installation tools have migrated upstream to the Debian installer. My current installation is Debian, using the 2.6.25-amd 64-bit kernel.

My MBP has been switched on for several hours as I write this, it sitting on a flat wooden tabletop (which is not the greatest surface for cooling): it is slightly warm to the touch on the LHS of the palm rest (above the HD); the bottom is likewise warm (not hot) near the power connector. The CPU frequency monitor shows both CPUs running at 800MHz (33%) most of the time; the hddtemp monitor shows the HD temperature as 40 deg C (just a bit above body temperature) and the CPUs at 32 deg C (room temperature is 23 deg C). The Airport (Broadcom 4328 rev 05) wireless is not used (although the modules are loaded and the wlan0 interface is available), connecting instead through the Ethernet port to a wireless bridge (due to WAP/WAP2 problems).

For reference, I'll show the output of lsmod

Note the cpufreq-related modules that seem to be doing a super job of keeping my MBP cool. I haven't bothered to monitor fan speed, since I can barely hear them spin even with my ears close to the keyboard. This is confirmed by
henk@mbp:~$ acpi -V
Battery 0: Full, 98%
AC Adapter 0: on-line
Cooling 0: Processor 0 of 10
Cooling 1: Processor 0 of 10
which shows the fans at their lowest settings (about 2000RPM, confirmed with the istat widget in Mac OS X).

Needless to say, I'm very pleased with this, the more so since all of the cpufreq stuff works out-of-the-box. I would encourage the OP to check his system to see whether acpi, cpufreq-utils and the like are properly installed (if necessary verify with an installation of Debian testing).

Well i can tell you that i can't wait this weekend... i'm gonna format my laptop again, to run ubuntu, but from the last post i want to know

1. what is this installation of Debian testing
2. what is you power configuration, i mean,., you use powernow or powersaved or cpufreq or cpudyn....please help me...

3. How do you get video output from your mac, i have this video card
Chipset Model: ATY,RadeonX1600
Type: Display
Bus: PCIe
PCIe Lane Width: x16
VRAM (Total): 256 MB
Vendor: ATI (0x1002)

Tks a lot

[cyberdork33]

Well i'm back on mac os, runs really good, but it' s not what i want...miss you ubuntu...lets hope that next one will be better

I will run ubuntu under virtual machine which one do you recomend?

1. VMfusion
2. Virtualbox
3. Parallels

TKS
My ranking:
1. VirtualBox
2. VMWare Fusion
3. Parallels

stream,
I would never recommend against PowerTop. It is of course how most of the power saving techniques I linked to were found.

Hajk,
You are a small minority from my experience here. It doesn't seem that you have really done anything special either is what's weird about it.

[hajk]

1. what is this installation of Debian testing
Well, "seek and ye shall find" the internet way (i.e. use Google). I'm not pushing the use of another OS in this Ubuntu forum, but you could try and do a trial install of Debian testing just to see that your MBP can run cool. Once that's confirmed (a big if), then you can try and duplicate settings on your Ubuntu installation.
2. what is you power configuration, i mean,., you use powernow or powersaved or cpufreq or cpudyn....please help me...For starters, you can compare the output of the "lsmod" command on your own system with that in my post -- do you see any mention of cpufreq there? If not, then you might look for a suitable package to install (use the search function in Synaptics). It is also possible that you have messed your system up by installing all sorts of packages, you could consider doing a clean reinstall.

You should consult the various MacBook Pro wikis, your machine is an older model that should be supported; there is also a new driver "radeonhd" for ATI cards that may be applicable to your machine (you may need to upgrade the kernel to 2.6.25, check backports).

I give all this advice in the hope that you will consider getting your MBP to run with Ubuntu an interesting challenge, for which you cannot wholly rely on other people giving you solution recipes. If you're not really interested in meeting such a challenge (and doing whatever it takes to surmount the problems), then you could still run Ubuntu in a VM... I like to use VMware Fusion for that running under Mac OS X: everything in Ubuntu works out-of-the-box, except a few key codes that are easily fixed.

Hajk,

Yeah, guilty as charged... could somebody running Ubuntu Hardy on a 4,1 MBP compare the output of "lsmod" with that in my earlier post? Does Ubuntu use the cpufreq modules? If not, there might be the key to the heat solution...

[fxjr]

Hi, all!

I have a macbook (not a pro) with ubuntu 8.04.1. And I can notice that it runs so cool or maybe even cooler than when running with osx.
I can only say this by puting my hands in the keyboard and seeing that it is not hot, only on the left size near charger but on osx it is also hot in this area.

Unfortunately, I can't get cpu temps because coretemp module on ubuntu doesn't recognize the model 17 45nm cpu. I'd like to know how do you get a module which works with macbook 4,1. This is the ubuntu bug handling this issue:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/235119


As was pointed out, I can barely hear the fans, which is nice. But does linux speed up my fans automatically or do I need to modprobe applesmc? I heard about crashs because of this module and so I didn't want to load it.

I'm liking very much Ubuntu on my macbook. Today the only problem I see is that sound is too low on ubuntu compared to osx. But of course this is another issue. Just talked here wondering if you have any idea if this could be fixed/improved or if I have to live with that.

Thanks in advance.

[Oscar Pradilla]

i can tell you..don't mess with that.... it work fine just that, i've done the test, it will keep it HD temp max 41, Core 35, something i don't know...62-95

I also have GREAT GREAT NEWS !!!

once again i'm on ubuntu (just ubuntu, not dual boot) i've tried this morning, and video output works just great...

is nice to be back....
