Public bug reported: On my Latitude 2110, the "dell_led" driver is useful for controlling the LED on the lid. However, the driver doesn't load automatically on boot, and so /sys/class/leds/dell::lid doesn't exist. I can load the module manually (with "sudo modprobe dell_led"), or I can put this line in /etc/modprobe.d/local-dell-led.conf:
alias wmi:F6E4FE6E-909D-47CB-8BAB-C9F6F2F8D396 dell_led If I do the latter, then the module loads automatically at boot. I note that "modinfo dell_led" says: alias: wmi:F6E4FE6E-909D-47cb-8BAB-C9F6F2F8D396 Note that the "47cb" there is in lower case. I suspect that this is the cause of the problem. I also note that the "hp_wmi" driver has a "wmi:" alias with lower-case letters in, so it may require a similar fix.
