Touchpad (ultranav): There are many reports of the touchpad pointer jumping around, and it does happen. However, it may be that certain 'synclient' settings need to be changed. The problem is annoying, but the touchpad is certainly useable.

The keyboard has a 'trackpoint', but this is only for moving the pointer. It provides no 'button' functions.

The capslock key has no LED (again mentioned in many reports). With KDE the notification system can be used to report when capslock is pressed (via the accessibility menu).

Initially the speaker mute (F1) key would light the micmute (F4) key LED as well. An updated acpid however configures the micmute key as F20, and adding a tiny ACPI script enables the micmute key LED to work. This means the F1 and F4 keys and corresponding LEDs now work independently.

I think (!) the WLAN disable key (F8) LED worked. Initially it didn't seem to, then I did something and it worked, but now it doesn't work. Not sure if the LED is faulty or not. The actual hardware disabling of the WLAN does work when using the key though.

Fingerprint reader: The fingerprint reader (Validity sensors VFS5011) is currently unsupported in Linux. However, it seems that some Ubuntu people have been working on this, and code has been written to support it. I have installed this on Fedora 20, and both the fingerprint reader and the code seem to work fine. The reader recognises one of my fingers everytime time, another about 1 in 4 times, and another it just doesn't recognise at all. This is about the same I got when I used a Toshiba laptop with fingerprint reader.


Overall, for general use, Linux (Fedora 20) ran out of the box on this laptop with the exception of the fingerprint reader.

VGAout works. I hooked up a Fujitsu monitor 1200p and it works. The same is not true with displayport. Running kernel 3.16 on Antergos (Arch derivative.) Bluetooth works as well, tried connecting a bt speaker and both the bt and pulseaudio seem to work, with some quirks albeit.
