asus_laptop issue, on Toshiba laptop, w/less led won't turn off
Having drawn a blank trying to solve an issue with my Toshiba Equium
L40 17M laptop I'm trying to gather information to slowly solve the
issue myself, even if it takes a year or more and feels like making a
guitar out of matchsticks.
I'd currently like to know what
happens in a laptop when one particular acpi module is blacklisted.
Though a Toshiba, this laptop uses the asus_laptop module for acpi, at
a guess for the same reason that when it had Vista it used an Asus
hotkey driver. If I blacklist asus_laptop most of the hotkeys still
work, though not the Fn and up/down arrows for volume control. I've
wondered if there is any danger to blacklisting the acpi module that
was actually in use.
Is there then another source for acpi or what is happening? Is there a
terminal command I can run to find out? Currently I have Ubuntu 11.10
on the laptop, for better or for worse. Using this (or Debian 6 or
Fedora 15) minus the blacklisting the wireless LED stays on regardless
of whether the wireless is on. Using Sabayon 7 as I was a week ago the
LED did not work whether the wireless was on or off. I am yet to check
whether it had the wrong acpi module running.
Pardon any naivety or wrong terminology. I do have a rich and creative
life and realise that this bug is minor but it's an enjoyable mystery
to put some time into all the same.
Better still, if someone reads this and thinks they might be able to
solve my issue let me know and I'll go into more detail.
