Blacklist acer_wmi in a Thinkpad

Hello,

I installed the last 2015.01.01 in my Thinkpad X200 and in each startup I have the driver acer_wmi is trying to load.

% journalctl -b | grep acer
Jan 30 16:12:04 X200 kernel: acer_wmi: Acer Laptop ACPI-WMI Extras
Jan 30 16:12:04 X200 kernel: acer_wmi: No or unsupported WMI interface, unable to load

I have no problem with this driver not loading, this is not an Acer laptop. The problem comes that the error message appears after the boot log clears and the pts/1 ask me for username and password.

I tried to blacklist it but does nothing. I have:

% cat /etc/modprobe.d/blacklist.conf 
blacklist acer_wmi
blacklist acer-wmi

Also, some other modules for other laptops are trying to load. For example:

% journalctl -b | grep apple             
Jan 30 16:12:04 X200 kernel: applesmc: supported laptop not found!
Jan 30 16:12:04 X200 kernel: applesmc: driver init failed (ret=-19)!

Where all this comes from? Thank you in advance.

RMMOD the modules ( go into a live linux session an use gtty ) mount your drive then unload the module ( ie apple acer wmi etc ) an keep it in the blacklist.conf ) an you should be good to go after that

Soldier, that makes no sense - even beyond the recurrent tpos.  The effects of rmmod only last for the current boot, so that would have no effect at all - and the OP is able to boot just fine, there is no need for a live medium (which makes the suggestion worse, as you'd even only be rmmod'ing the module from the current boot of that other kernel).

joksnet, it looks like something else is loading that module.  Do you have any laptop tools or modules installed?

Re: Blacklist acer_wmi in a Thinkpad

If you look at the output of:

lsmod|grep -e acer_wmi -e acer-wmi -e applesmc

That should give you a list of any other modules that depend on those three -- you will need to blacklist these as well.

EDIT: Added applesmc
