===== Tweaks =====

==== Console ====

  * Add //kld_list="i915kms"// to ///etc/rc.conf// in order to increase font size in the console (this kernel module is loaded automatically anyway when you start the X server).

==== Installation ====

Installation works fine from memstick in UEFI mode.

==== Xorg ====

=== Touchpad ===

Two-finger scrolling does not work out of the box.

I've tried adding the following mouse configuration into  ///usr/local/etc/X11/xorg.conf.d/10-mouse.conf// but without success:

<code>
Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "CorePointer"
        Option      "Protocol" "auto"
        Option      "Device" "/dev/sysmouse"
        Option      "ZAxisMapping" "4 5 6 7"
        Option      "Emulate3Buttons" "false"
EndSection
</code>

==== sound workarounds ====

Might not be necessary on 12.1-RELEASE.
