Yes, there is a command. Detecting sensors First of all, you have to search for sensors: sudo sensors-detect Since lucid lynx, you have to type: sudo service module-init-tools start If you're running another Ubuntu version type: sudo /etc/init.d/module-init-tools start To save the detection results. Displaying sensor data Now, to show the ...

An alternative for nvidia cards is to use nvidia-smi: the "NVIDIA System Management Interface program". user@box:~$ nvidia-smi -q -d temperature GPU 0: Product Name : GeForce 210 PCI ID : a6510de Temperature : 39 C Or to output just the numeric value in Celsius: user@box:~$ ...

If you want something that does not depend on a desktop: Have a look at lm-sensors . From the description: Lm-sensors is a hardware health monitoring package for Linux. It allows you to access information from temperature, voltage, and fan speed sensors. It works with most newer systems. This package contains programs to help you set up and read data ...

Quick command-line solution cat /proc/acpi/thermal_zone/THRM/temperature. Applet If you are looking for a easier-to-access version, add a Hardware Sensors Monitor to Gnome-Panel: sudo apt-get install sensors-applet - this will install the sensors applet package Right-click the panel, select Add to panel..., then select this: You're done. You can ...

I have here a rather old Thinkpad with a Mobility Radeon HD 3400 series card, having similar problems: The closed-source fglrx driver is almost unusable, due to flickering, glitches, etc with gnome-shell. The open-source radeon driver is working very nice, but the card gets too hot. Checking using cat /proc/acpi/ibm/thermal shows that the card heats up to ...

The high temperature is caused by the poor power management of the open source drivers. Installing the latest proprietary drivers would help, if official support for the HD4xxx series hadn't been dropped with Quantal. So you're left with two options: 1.) Install the legacy FGLRX drivers through a custom PPA that ships with an older version of X.ORG. ...

Well found a way to lower the hard drive temperature, had to stay up all night. (Gave a +1 to Ringtail's comment ;) ) Open Dash and type disks. You will see the Disks Utility pop up. Open it. Now select the Hard Drive you wish to work with and then, in the green circle above, there is a button, click on it and select Drive Settings... Depending on ...

Depending on your hardware the sensors on your motherboard need additional calibration. Unfortunately the standard values given in /etc/sensors.conf and in /etc/sensors3.conf can only give you rough estimates because of variations in your hardware. However there is nothing that can't be set up. There are many self-explanatory notes in the sensors.conf file ...

Thermal sensor are specific to a each computer type. For example, the IBM/Lenovo Thinkpad series sensors are described here http://www.thinkwiki.org/wiki/Thermal_sensors Try to search the Internet for you laptop type and see where each sensor is positioned.

For logging of cpu/ram/temperatures/traffic on a server, I recommended Cacti. It is advertised as a 'complete frontend for RRDtool', and can have multipled data sources such as lm-sensors, SNMP or even custom scripts. Data is stored in RRD, and used to create daily, weekly, monthly and yearly graphs. See the Cacti website for more details, screenshots ...

On this webpage there is a bash script that will attempt to keep your CPU below a specified temperature. http://seperohacker.blogspot.com/2012/10/linux-keep-your-cpu-cool-with-frequency.html You just need to provide it with your desired maximum temperature, and it will throttle your CPU(s) in an effort to stay below that temperature. Shameless plug- I ...

Fans are normally controlled by the hardware in response to temperature, so you don't need to worry about it -- if the system gets too warm, it will speed up the fans automatically. You may be able to setup lm-sensors to detect the fan controller and the fancontrol package to take over, but this is not easy nor a good idea. You would start with running ...

If it has been a year, then it is time to clean the dust out again, and make sure that the fan is spinning correctly. If there is no significant dust and the fan is spinning ( at the correct speed ), then you may try removing the heatsink, cleaning and reapplying the thermal paste. You also might try the boot option pcie_aspm=force as some people have ...

lm-sensors only reads raw data of the in-built sensors. in fact there is no normalisation imposed to the manufacturers. (they can build how many sensors they want and where they want). so in some case info is clear (like in previous example) in some others info is less pertinent. you can only make supposition. only the manufacturer could tell you.

Things will start to melt when you go over 140°C. Things both in and around the CPU. 231°C is actually beyond the ignition temperature of a lot of plastic components that may be in your computer. That's a bad situation. Given your desktop hasn't reduced itself to a flaming puddle (yet) I'm going to say this is almost certainly a bug in lm-sensors or the I²C ...

You can use psensor to monitor the computer temperature. This is a GUI application that readout the CPU and Mainboard sensors. sudo apt-get install psensor After starting psensor, go to the "Sensor preference Menu", choose your CPU sensor and click on Alarm - Activate Desktop Notifications. You can modify the temperature limit for your needs.

If you have not yet run sudo sensors-detect then you will need to do that. You'll also want to have it modify the modules.conf at the end if it detected new kernel modules that need to be loaded, so that they will be reloaded on reboots. After that, sensors should report more information. If not, it's possible the sensors in your system are unsupported, or ...

Install Jupiter and jupiter-support-eee. This is a frontend to the acpi power states and works by undervolting the CPU and Mainboard. It will reduce power consumption at the price of preformance of course. sudo add-apt-repository ppa:webupd8team/jupiter sudo apt-get update sudo apt-get install jupiter jupiter-support-eee reduce the backlight as far as ...

Normally I would suggest ripping out the graphics card but that's usually not an option in laptops. It might be worth exploring though. When you run a graphical environment, most users use the nvidia kernel module. This manages the power consumption of the graphics card by helping scale back the clock speed when it's under lower loads and upps the fan speed ...

'Cpu frequency control' provides what you want, so you should install indicator-cpufreq package. sudo add-apt-repository ppa:artfwo/ppa sudo apt-get update sudo apt-get install indicator-cpufreq And Launch "Startup Applications" Then click "Add" to add a new startup application. In command area type indicator-cpufreq , in name area type whatever you ...

This is probably related to the implementation of Adobe Flash (in Ubuntu, or even in general); while the video codecs used by youtube are standardized, how they are implemented is up to Adobe and it may well be a poor implementation and/or one that uses the GPU excessively. Compared to that, most Linux/Ubuntu video apps use the FFmpeg/libavcodec open-source ...

I'm assuming you are still using lucid: You can now install the 2.6.38 kernel from synaptic manager without needing to add PPAs or needing to download the kernel itself from the mainline kernel repository. Start Synaptic Manager and search for "2.6.38". Install the generic linux 2.6.38 image and headers packages. If necessary, also install the backports ...

If you do not install the appropriate driver you can't blame the system for this behaviour. install the latest AMD ATI proprietary driver and everything will work ok, refer to this page for info http://wiki.cchtml.com/index.php/Main_Page and i reccomend to install this driver by generating the .deb packages.

You are are not specifying which model of cpu you are running, there are multiple i7 processors. For Sandy Bridge the maximum temperature is 100degrees C., so, you are well inside the parameters. Here you can you can browse some charts.

It's very difficult to make a direct comparison between one OS and another temperature wise as the programs that collect the data from the temperature sensors in your machine do that in different ways. For instance two different programs in windows can give different results about the same computer at the same time. I'm sure that the Canonical testing team ...

For nvidia there is an nvidia-settings package, which includes a gui to see the temperature. I don't recall if there is a text-mode tool in there. Some Intel graphics adapters report their temperature through acpi and you can read it through the sensors command from the package of the same name.
