Both of these also failed with Permission denied errors

Further research shows that the use of /proc/acpi/thermal_zone has been
deprecated for some time. The new location is /sys/class/thermal.
I have not found any specific reference about the current state of usage
of /proc/acpi/fan, but from some reading and kernel.org (below), I think

I posted some of this material in the thread "Lubuntu: acerhdf.conf,"
but am starting a new thread that better reflects what I'm trying to

1) BIOS/UEFI
2) Bus signalling to PWM controllers governing fans [the lm-sensors
