# aptitude install lm-sensors
# /usr/sbin/sensors-detect This program will help you determine which I2C/SMBus modules you need to load to use lm_sensors most effectively. You need to have i2c and lm_sensors installed before running this program. Also, you need to be `root', or at least have access to the /dev/i2c-* files, for most things. If you have patched your kernel and have some drivers built in, you can safely answer NO if asked to load some modules. In this case, things may seem a bit confusing, but they will still work. It is generally safe and recommended to accept the default answers to all questions, unless you know what you're doing. We can start with probing for (PCI) I2C or SMBus adapters. You do not need any special privileges for this. Do you want to probe now? (YES/no): yes
Probing for PCI bus adapters... Use driver `i2c-viapro' for device 00:11.0: VIA Technologies VT8237 South Bridge Probe succesfully concluded. As you are not root, we can't load adapter modules. We will only scan already loaded adapters. If you have undetectable or unsupported adapters, you can have them scanned by manually loading the modules before running this script. To continue, we need module `i2c-dev' to be loaded. If it is built-in into your kernel, you can safely skip this. i2c-dev is not loaded. As you are not root, we will just hope you edited `/etc/modules.conf' for automatic loading of this module. If not, you won't be able to open any /dev/i2c-* file. We are now going to do the adapter probings. Some adapters may hang halfway through; we can't really help that. Also, some chips will be double detected; we choose the one with the highest confidence value in that case. If you found that the adapter hung after probing a certain address, you can specify that address to remain unprobed. That often includes address 0x69 (clock chip). Some chips are also accessible through the ISA bus. ISA probes are typically a bit more dangerous, as we have to write to I/O ports to do this. This is usually safe though. As you are not root, we shall skip this step. Some Super I/O chips may also contain sensors. Super I/O probes are typically a bit more dangerous, as we have to write to I/O ports to do this. This is usually safe though. As you are not root, we shall skip this step. Sorry, no chips were detected. Either your sensors are not supported, or they are connected to an I2C bus adapter that we do not support.

$ sensors Can't access procfs/sysfs file Unable to find i2c bus information; For 2.6 kernels, make sure you have mounted sysfs and done 'modprobe i2c_sensor'! For older kernels, make sure you have done 'modprobe i2c-proc'!
