## 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's no such connector on a T460s):

    video=SVIDEO-1:d

### Fingerprint Sensor

The fingerprint sensor built into the T460s is currently not supported by Fprint.

### 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: [1] [2].

This can be worked around by using the `i915.enable_rc6=0` kernel parameter [3] (cf. Intel graphics#Skylake support)

### Smartcard Reader
