To be able to use a secondary screen you need to be running on your discrete graphics card. It all comes down to some Mac hardware specifics quirks.

When booting in legacy boot mode on mac hardware with two cards the discrete card is not available for use and powered of completely.

  1. You need to boot in EFI mode for the discrete card to be visible. (To quickly test this part try booting on a USB stick in EFI mode and you should see two cards with lspci)

  2. Then Switch to using the discrete card using vgaswitcheroo as root run:

echo "DIS" > /sys/kernel/debug/vgaswitcheroo/switch

to switch to the discrete card. This should be run from console with X session stopped.

You don't specify how you use OpenVPN . Is it through network manager or as a daemon?

So I will assume its using network manager

under: network-manager -> you-vpn-profile-name -> ipv4 -> "use this connection only for resources on its network"

If this checkbox is unchecked it will route all traffic over your tunnel

Does your laptop have two graphics cards? do you EFI boot or legacy mode boot Fedora?

Using a 64 bit kernel , whenever your hardware supports it will gain you some performance and is therefore always recommended as it guarantees that the all the applications you run have been compiled to support modern processor instructions

If you have uninstalled the kernels still showing up in refit/refind

I believe its because the files exist or have been copied to /boot/efi/EFI

remove each unwanted folder there that contains the extraneous kernel and vmlinuz and the entries will disappear from refind

Its actually configurable for the libinput driver for Xorg even though you can't find any GUI setting for it in Fedora 23 under mouse & touch pad

open the file /usr/share/X11/xorg.conf.d/90-libinput.conf

Under the section for the device with the identifier "libinput touchpad catchall" add the optioons

Option "PalmDetection" "True"
Option "DisableWhileTyping" "true"

Will require a logout to take effect. works great on my touch pad but I have a Macbook so might not work as well for other touchpad devices.
