Troubleshooting
Wacom Digitizer (056a:5002)
Requires a custom module not currently avalable in the stock 3.14.4-1-ARCH kernel.
See Hardware Modules for how to enable the digitizer
Fingerprint reader
According to the Fprint wiki, the reader does not appear to be a supported model. If the reader is unused, it is recommended that the device be physically disabled in the bios.
Fan noise
Fan noise was an issue on initial BIOS revisions. The change log for BIOS version 1.08 noted a fan settings update which has since resolved the fan noise issue.
User confirmations of the fix may be found after post #540 [1]
Hardware modules
Wacom Digitizer
The wacom kernel module (wacom.ko) loaded by default in the 3.14.4-1-ARCH kernel does not support the T904's integrated digitizer 056A:5002 (VendorID:DeviceID). However, the Linuxwacom project has included support in their upstream kernel module and xf86-input-wacom-git package which are not yet available in the official arch repositories.
Until future updates are released, users may obtain a functional digitizer by installing xf86-input-wacom-git and building the kernel module as described below:
X11 wacom input
Install xf86-input-wacom-git via building from source or using an AUR helper)
Wacom Kernel Module
The non-functional default wacom kernel module (wacom.ko) is located in /lib/modules/3.14.-4-1-ARCH/kernel/drivers/input/tablet/wacom.ko This module must be replaced with the latest Linuxwacom project module as follows:
First, ensure that git and linux-headers are installed:
# pacman -S git linux-headers
Create a new directory to build the wacom.ko module in:
$ mkdir ~/builds $ cd ~/builds
Download the latest module source from the Linuxwacom project:
git clone git://git.code.sf.net/p/linuxwacom/input-wacom
Build the module with autogen.sh:
# bash ~/builds/input-wacom/autogen.sh
As described in the autogen.sh output, copy the module to the appropriate directory:
# cp ~/builds/input-wacom/3.7/wacom.ko /lib/modules/3.14.4-1-ARCH/kernel/drivers/input/tablet
In case the old wacom module was previously loaded, ensure it is removed:
# rmmod wacom.ko
Insert the new module:
# insmod ~/builds/input-wacom/3.7/wacom.ko
Ensure modprobe has the correct aliases:
# depmod -a
