How can I find out the cpu temperature of my linux desktop? What does

acpi -t

measure? The man page doesn't really say more than 'thermal information'. Judging from ACPI = advanced config and power interface, and the fact that all googles for info about that command brings up forum posts about laptops, I would guess it's battery temp? Please help...

Thanks

Type sudo apt-get install lm-sensors (once), then sensors (every time you want to check) in a terminal window.

thanks for the answer - this works perfectly! Also, searching for lm-sensors in synaptic led me to discover 'psensor' which is a graphical monitor that also shows gpu temp.. – noobler Oct 4 '12 at 0:23
    
There's hddtemp as well, and I've used Gnome panel applets like sensors-applet and computertemp in the past. – Karan Oct 4 '12 at 0:26

1) Install the lm-sensors packet: sudo apt-get install lm-sensors

2) Start the sensors detection: sudo sensors-detect

3) In a terminal run sensors to read the sensors data...

Details: lm-sensors packet install these files:

System executables in /sbin (system binaries):

/usr/sbin/fancontrol /usr/sbin/pwmconfig /usr/sbin/sensors-detect

The sensors utility in

/usr/bin/sensors

The shell scripts in /etc/init.d

/etc/init.d/lm-sensors allow to start, stop or restart the daemon /usr/bin/sensors
