Title:
[Dell Latitude 2110] dell_led driver does not auto-load (bad alias)
Status in linux package in Ubuntu:
Incomplete
Bug description:
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.
