I have a Dell Latitude 2120. On boot, /sys/class/leds/dell::lid does not exist because the dell_led module isn't loaded. It does after running 'sudo modprobe dell_led'. However, without doing anything else:
hitechcomputergeek@hitechcomputergeek-Latitude-2120:~$ modinfo dell_led filename: /lib/modules/3.16.0-37-generic/kernel/drivers/leds/dell-led.ko alias: wmi:F6E4FE6E-909D-47cb-8BAB-C9F6F2F8D396 license: GPL description: Dell LED Control Driver author: Louis Davis/Jim Dailey srcversion: 9EE537D53326E7266C67193 depends: wmi intree: Y vermagic: 3.16.0-37-generic SMP mod_unload modversions 686 signer: Magrathea: Glacier signing key sig_key: 32:23:0C:F4:08:B3:8C:6D:FA:DB:53:FC:8B:F0:61:69:33:CE:13:D2 sig_hashalgo: sha512 Note the lowercase '47cb'. Also, I managed to track down the source file for this kernel module on kernel.org. In it, the identifier (whatever you should call it, GUID?) is hardcoded with the lowercase '47cb'. The file: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/leds /dell-led.c I'm not sure that the lowercase '47cb' is what's causing the module to not autoload, or if it should autoload in the first place. But I still feel that the '47cb' should be '47CB'. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1399952 Title: [Dell Latitude 2110] dell_led driver does not auto-load (bad alias) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-utopic/+bug/1399952/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
