Notebook with Debian too hot?

talles · 2012-07-24 17:00:28

I got a notebook with a Debian install along with Windows 7.

The temperature showed by Conky seems OK (I wonder if it's right), something around 66°C. But the notebook feels a lot hotter running Debian than Windows 7. You can clearly sense it, it's way more hot than running Windows.

I got a 'fresh' Debian install and I never really configured such thing (used to use on Desktops).
What should I configure/install?

Any utility that controls the CPU frequency? Any graphical one?

I'm running 64-bit Debian Squeeze with openbox+tint2 in a pretty much a standard notebook, LG brand with Core i3 processor and no dedicated video card.

Thanks in advance.

Mister K would probably add this to your

/etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet i915.lvds_downclock=1 i915.i915_enable_fbc=1 i915.i915_enable_rc6=1"

Then:

sudo update grub

and reboot.

Do you have lm-sensors installed? Install it and run it for the first time:

sudo sensors-detect

Then just:

sensors

and it will give you some output.

And of course cpufrequtils.

Edit: Thanks pidsley! Typo.

I think you missed a "G" there at the beginning, Ivan.

talles, if your conky is already showing CPU temp, you probably don't need to run sensors-detect, just run

sensors

in a terminal, and if it says "no sensors found!" then you need to run sensors-detect.

^ Oops! Corrected.

Thank you for the answers guys.

The sensors seems to be ok.

About the overheat, I added those parameters but after doing it my X wouldn't start (the system boots to console instead of the session manager screen and startx fails).

Checking dmesg I've seen that it complains both about the options i915_enable_fbc and i915_enable_rc6; it says that they are unknown parameters. I was able to use the lvds_downclock option though.

Unfortunately, I haven't got time this week to use the notebook; I used just for half hour, after adding downclock to 1 in grub, and I don't know if it helped or not but still quite hotter than while on Windows.
I'm going to use it for longer today when I got home (friday eh) and see what happens, but I'm afraid that still no good.

Maybe I need to update something to enable fbc and rc6? I'm sorry my knowledge in this area is fairly low (none actually).

Anyway I tried using it cpufreq but I don't know if I'm using right.
I tried to do cpufreq-set -g powersave but I don't know if will help. I checked several times and the frequency was already at the lower one, despite setting the governor or not. I dunno if it will help anyway. The governor when the system loads is ondemand.

Another odd thing: I don't know exactly if this is just because it is a lot hotter than I'm used too or something else is overheating (GPU probably, right?), but other 'regions' of the notebook seems to get hot as well (that I'm not used to seeing getting hot).

Thanks a bunch guys.

Hi

I had once similar problems on my Core I5 notebook.

I solved this temporarily by adding some, not all of the parameters mentioned in the previous post.

Since i am on the latest liquorix kernel 3.4.0-6.dmz.1-liquorix-amd64 the machine is perfect w/o any additional boot parameters. Maybe you give this a try as well.

What kind of graphics card do you have? I didn't check temperatures, but when I first installed Crunchbang on my Dell Studio 1557, the fan constantly ran. The resolution was to install the proprietary AMD driver for my graphics card. Check out this post for more info: http://crunchbanglinux.org/forums/topic … n00b-here/. PM me if you're interested in a cheat sheet I put together that includes screenshots.

I tried liquorix, but it won't boot. It gives a kernel panic, VSF: Unable to mount root fs on unknown-block(0,0).

I tried updating the traditional kernel from wheezy repo (2.6 to 3.2), and it worked. Those parameters are working now and the temperature is OK.

Thanks for the help.

By the way, where my right hand rests got a unusual warm (not really a overheat). Any other tip to try?
