Lenovo Yoga 2 11
To access the boot menu and BIOS, use the "alternative" power button: a small circular one on the right, next to the main power button.
Disable secure boot from the BIOS. Only the UEFI boot mode appears to be available, but the Arch Linux install ISO used supports UEFI boot.
To enable the wifi card, first run
rfkill unblock all
returned no scanning results, however
iwlist wlp1s0 scan
confirmed the wifi card was working. I was able to get a connection by setting up a netctl profile manually.
The power button works out of the box, however the system reboots after shutdown. This appears to be an xhci-hcd kernel module bug and can be worked around by unloading the xhci_hcd module before shutdown. This can be done via systemd by creating a unit file /etc/systemd/system/xhci.service containing
[Unit] Description=rmmod xhci_hcd [Service] Type=oneshot ExecStart=/bin/true ExecStop=/usr/bin/rmmod xhci_pci && /usr/bin/rmmod xhci_hcd RemainAfterExit=yes [Install] WantedBy=default.target
and enabling it with
systemctl enable xhci
To use the unit immediately, you will also have to start it
systemctl start xhci
There is a Windows button by the screen, however key down events are only reported when the button is released (in tandem with the key release event).
