Hi, Jean, one (hopefully last) question to you: Running # sensors -s I get w83781d-i2c-0-2d: Can't access procfs/sysfs file for writing; Run as root?

I checked lm_sensors-2.8.6/doc/lm_sensors-FAQ.html Section 4.20 regarding Linux 2.4. Looks like - for 2.4, lm-sensors-2.8.4 is expected, - for 2.6, lm-sensors-2.8.6 is expected ??? But with lm-sensors-2.8.4, I did not get the whole thing to work ... grrr... and I thought I were through, at least for the time being ... - Manfred
