On my desktop PC running Ubuntu 11.10 with 3.0.0-24-generic-pae kernel
I have /sys/class/backlight/eeepc-wmi symbolic link pointing to
/sys/devices/platform/eeepc-wmi/backlight/eeepc-wmi
My PC is non an EEEPC. Perhaps Linux kernel wrongly detects type of
hardware,
I don't know. I just have a PC with an LCD monitor.
P.S.
By the way, when I use the default mobile kernel without needed CONFIG_s
I have
several more division by zero since PowerTOP uses default value of 0 to
lot's of variables.
But since that CONFIG_s are required to run PowerTOP I have not reported it.
