Configuration
flip_done timed out freezes
See this thread for some discussion. You can either move back to a <4.8 kernel by using linux-lts, or add the following parameter to your kernel command line, which seems to help (it disables S-Video, but there is no such connector on a T460s):
video=SVIDEO-1:d
Fingerprint Sensor
The fingerprint reader included with this model `138a:0090 Validity Sensors, Inc` currently lacks a linux driver. libfprint bugreport. Synaptics (which has acquired 'Validity Sensors') has unofficially said that they cannot disclose the protocol, but may possibly release a binary driver.
Open source Linux driver is being developed by reverse engineering the Windows driver [1]. Based on this work an experimental fprint driver was developed: libfprint-vfs0090-gitAUR [2].
ALSA Beep
There is no "beep" input to the snd_hda_intel device, so beeps generated by terminal emulators etc. are not played. As a workaround, PulseAudio can be configured to pick up X11 bell events, see PulseAudio#X11 Bell Events.
Function keys
Fn+Esc to enable FnLk which will make your function keys work.
Video Issues
With newer kernels (>= 4.5), there seems to be video flickering, i.e. the screen occasionally goes black for what seems to be a single frame. See bug reports: [3] [4].
This can be worked around by using the i915.enable_rc6=0 kernel parameter [5] (cf. Intel graphics#Skylake support[broken link: invalid section])
Smartcard Reader
Bus 001 Device 003: ID 058f:9540 Alcor Micro Corp. AU9540 Smartcard Reader
Install the ccid and pcsc-tools packages, and enable the pcscd service. The reader should be visible when running pcsc_scan:
pcsc_scan PC/SC device scanner V 1.4.27 (c) 2001-2011, Ludovic Rousseau <ludovic.rousseau@free.fr> Compiled with PC/SC lite version: 1.8.16 Using reader plug'n play mechanism Scanning present readers... 0: Alcor Micro AU9560 00 00 Wed Sep 7 16:48:42 2016 Reader 0: Alcor Micro AU9560 00 00 Card state: Card removed,
Sound
If the sound quality is bad, updating /etc/modprobe.d/modprobe.conf with
options snd-hda-intel model=tpt460
may improve it. These options are documented [6][7] in the Linux kernel.
