After installing the lm-sensors package it's usually good to probe available sensors unless those supported by the motherboard are already known. However, in Dapper (8.04) the user will get the following error
$ sensors-detect No i2c device files found. Use prog/mkdev/mkdev.sh to create them.
and that mkdev.sh or similar is nowhere to be found. Here's a script that will do what needs to be done:
#!/bin/bash # Here you can set several defaults. # The number of devices to create (max: 256) NUMBER=32 # The owner and group of the devices OUSER=root OGROUP=root # The mode of the devices MODE=600 # This script doesn't need to be run if devfs is used if [ -r /proc/mounts ] ; then if grep -q "/dev devfs" /proc/mounts ; then echo "You do not need to run this script as devfs is used." exit; fi fi i=0; while [ $i -lt $NUMBER ] ; do echo /dev/i2c-$i mknod -m $MODE /dev/i2c-$i c 89 $i || exit chown "$OUSER:$OGROUP" /dev/i2c-$i || exit i=$[$i + 1] done #end of file
Copypaste that to your favorite editor, save as mki2cdev.sh, give it execution bits
chmod a+x mki2cdev.sh
and run it once as root
and continue with sensors-detect. That error should finally be gone and sensors detected as wanted.
