Installing Sabayon

Wireless

Install a kernel >= 3.11.6 and make sure CONFIG_IWLMVM is enabled. the iwlwifi module should be automatically loaded and wifi just works.

Audio

Mostly just works.

There are two physical sound cards, both driven by the snd-hda-intel driver. The HDMI card is always detected first, and the analog (speakers and headphones) second. Reorder these to make the analog the default by /etc/modprobe.d/alsa.conf to contain the following

options snd-hda-intel index=1,0

KDE defaults to letting the multimedia volume keys (Fn+F1/F2/F3) control the HDMI card by default. Switch this to the analog card by opening KMix and setting Settings→Select Master Channel…→Built-in Audio Analog Stereo.

If there's no sound when logging into plasma (the volume icon has a red cross through it, and the kde settings shows no devices), make sure pulseaudio user daemon is running, and if not start it one-time with pulseaudio -D,

Graphics

After installing and upgrading to latest i915 driver, remove nomodeset from the kernel boot options. This will enable screen brightness control and fix sleep/resume.

Install bumblebee and enable the service to use optimus. Run programs using optirun to enable the discrete graphics card.

Nice feature, the screen brightness can be turned all the way down to zero, which turns the screen and backlight off.

DPI

Because of the high resolution, text will be very small by default. Change the DPI size in KDE to make all KDE applications well-behaved (konsole, plasma).

Still working on fixing non-KDE programs such as chrome.

Bluetooth

* Enable the bluetooth

systemctl enable bluetooth
systemctl start bluetooth

* Use bluetoothctl to enable the controller, scan and pair with devices, and connect

# Start the shell
bluetoothctl -a
# Turn on the controller
power on
agent on
default-agent
# Scan for devices
scan on
# List available devices
devices
# Pair with a device
pair $mac
# Connect to the device
connect $mac

The error message:

Nov 24 12:33:22 serenity.jellybean.sihnon.net bluetoothd[10758]: Endpoint replied with an error: org.freedesktop.DBus.Error.AccessDenied

is fixed by amending /etc/dbus-1/system.d/bluetooth.conf to match:

  <policy user="root">
    <allow own="org.bluez"/>
    <!-- Add this line below -->
    <allow send_type="method_call"/>
    <allow send_destination="org.bluez"/>

Set the preference for certain types of audio (e.g. Music) to route through the bluetooth device when present using the Multimedia applet in KDE's control centre.

Touch screen

Out of the box, single touch input works but no gestures. This means you can touch to click, and drag to select. No scrolling, or pinch-to-zoom.

Install and run touchegg to get multitouch gestures. touchegg, touchegg-gui (configuration tool), and dependencies (utouch-{evemu,frame,grail,geis}) are in the sihnon portage overlay and community entropy repo.

USB

Just works.

Flashing BIOS

ZFS root

Kernel package installations run sabayon-dract –rebuild x.y, which invokes dracut with a bunch of module omissions including all the systemd ones needed for ZFS to work. Therefore whenever upgrading the kernel, be sure to run dracut -f /boot/initramfs-genkernel-x86_64-$(uname -r) $(uname -r).

Grub 2.02-r3 ships a version of grub2-probe which can't handle ZFS properly. This means the generated grub config file will contain root=ZFS=/root instead of root=ZFS=rpool/root which breaks root filesystem mounting. After installing grub or any kernel package, fix grub,cfg before rebooting.

Troubleshooting

Failure to boot from ZFS root

Errors on startup about system not having been booted with systemd. This is a problem with the dracut initrd.

Manual boot:
