• Configurazione solo con Intel
  Nel file /etc/X11/xorg.conf.d/20-intel.conf usare questa configurazione:

  Code: Select all

  Section "Extensions"
     Option "XVideo" "Disable"
  EndSection
  
  Section "Device"
     Identifier  "Intel Graphics"
     Driver      "intel"
     Option      "AccelMethod"  "sna"
     Option      "TearFree"     "true"
     Option      "DRI"         "true"
  EndSection

• Configurazione Intel/NVIDIA con Bumblebee e primus
  Bumblebee e primus permettono di eseguire dei programmi utilizzando la scheda NVIDIA al posto di quella intel integrata.
  Installare primus

  Code: Select all

  # emerge primus

  Oltre a questo ho dovuto smascherare anche la versione 361.28-r2 dei driver NVIDIA e attivare la use flag compat:

  Code: Select all

  # echo "=x11-drivers/nvidia-drivers-361.28-r2 ~amd64" >> /etc/portage/package.accept_keywords/nvidia
  # echo "x11-drivers/nvidia-drivers compat" >> /etc/portage/package.use/nvidia
  # emerge nvidia-drivers

  Ora si deve configurare bumblebee, per prima cosa bisogna spostare la configurazione della scheda grafica intel da /etc/X11/xorg.conf.d a /etc/bumblebee:

  Code: Select all

  # mv /etc/X11/xorg.conf.d/20-intel.conf /etc/bumblebee/xorg.conf.intel

  poi si deve creare la configurazione per la scheda NVIDIA quindi editare /etc/bumblebee/xorg.conf.nvidia e copiare la seguente configurazione:

  Code: Select all

  Section "ServerLayout"
      Identifier  "Layout0"
      Option      "AutoAddDevices" "false"
      Option      "AutoAddGPU" "false"
  EndSection
  
  Section "Device"
      Identifier  "DiscreteNvidia"
      Driver      "nvidia"
      VendorName  "NVIDIA Corporation"
      BusID  "PCI:1:0:0"
      Option "NoLogo" "true"
      Option "UseEDID" "false"
      Option "UseDisplayDevice" "none"
  EndSection

  Una volta create le configurazioni per le due schede video editare il file /etc/bumblebee/bumblebee.conf e cambiate sotto la sezione [optirun] la voce Bridge da auto a primus

  Code: Select all

  ...
  [optirun]
  Bridge=primus
  ...
  

  eliminate tutte le sezioni dei driver e sostituire con queste:

  Code: Select all

  ...
  [driver-nvidia]
  KernelDriver=nvidia
  PMMethod=auto
  LibraryPath=/usr/lib64/opengl/nvidia/lib:/usr/lib32/opengl/nvidia/lib:/usr/lib/opengl/nvidia/lib
  XorgModulePath=/usr/lib64/opengl/nvidia/lib,/usr/lib64/opengl/nvidia/extensions,/usr/lib64/xorg/modules/drivers,/usr/lib64/xorg/modules
  XorgConfFile=/etc/bumblebee/xorg.conf.nvidia
  
  [driver-intel]
  KernelDriver=i915
  PMMethod=auto
  XorgConfFile=/etc/bumblebee/xorg.conf.intel
  ...

  Ora bisogna assicurarsi che opengl sia settato su xorg-x11:

  Code: Select all

  # eselect opengl list
  Available OpenGL implementations:                                                                                                                   
    [1]   nvidia                                                                                                                                    
    [2]   xorg-x11 *

  se non dovesse essere il caso lanciare il comando:

  Code: Select all

  # eselect opengl set 2

  Per finire basta attivare il servizio di bumblebee e aggiungerlo al runlevel di default (se si vuole che parta a ogni riavvio):

  Code: Select all

  # /etc/init.d/bumblebee start
  # rc-update add bumblebee

  Fatto questo lanciando qualsiasi programma con optirun verra' eseguito con la scheda NVIDIA invece con quella Intel.
  Per testare se funziona tutto scaricate il pacchetto x11-apps/mesa-progs e lanciate i seguenti comandi dove dovrebbe vedersi una volta che usa la scheda Intel e nell'altro caso quella di nvidia:

  Code: Select all

  $ glxinfo | grep OpenGL

# emerge dmidecode

# dmidecode -s bios-version
01.01.19

• Copiare il file dell'aggiornamento del BIOS (.exe) sulla chiavetta
• Riavviare e usare F12 per potere fare il boot da usb
• Scegliere la voce con FreeDOS e poi scegliere "Load FreeDOS without drivers" (o qualcosa del genere)
• Ora siete in ambiente DOS e dovete scegliere il drive della chiavetta usb (solitamente il C o il D) e lanciare il file .exe per fare l'update del BIOS

• Freeze random del sistema
  Purtroppo la tecnologia Skylake sembra avere qualche piccolo problema che causa dei freeze del sistema. Per fortuna esiste un workaround che consiste nel fare partire il kernel con il parametro intel_idle.max_cstate=7 (per maggiori informazioni leggere qui). Per fare questo basta aggiungere nel file /etc/default/grub la seguente linea:

  Code: Select all

  GRUB_CMDLINE_LINUX_DEFAULT="intel_idle.max_cstate=7"

  poi lanciate il comando:

  Code: Select all

  grub2-mkconfig -o /boot/grub/grub.cfg

• Scheda grafica intel con kernel <4.3.X
  Se usate un kernel <4.3.X bisogna aggiungere in /etc/default/grub la seguente linea:

  Code: Select all

  GRUB_CMDLINE_LINUX_DEFAULT="i915.preliminary_hw_support=1 nouveau.modeset=0 intel_idle.max_cstate=7"

  e poi lanciare il comando

  Code: Select all

  grub2-mkconfig -o /boot/grub/grub.cfg

• Bluetooth
  Nel pacchetto manca il firmware del bluetooth per ovviare a questo scaricare il seguente file e copiarlo in /lib/firmware/brcm/

  Code: Select all

  # mv BCM-0a5c-6410.hcd /lib/firmware/brcm/

• Resume wirless
  Quando avviene il resume la wireless non si riattiva, per ovviare a cio' creare il file /etc/pm/sleep.d/00_wireless_sleep e copiare il seguente codice:

  Code: Select all

  #!/bin/sh
  case "$1" in
  suspend|hibernate)
  /sbin/rmmod brcmfmac
   ;;
  resume|thaw)
   /sbin/rmmod brcmfmac
   /sbin/modprobe brcmfmac 
  ;;
  esac
  exit 0

  poi si renda lo script eseguibile:

  Code: Select all

  # chmod +x /etc/pm/sleep.d/00_wireless_sleep

• Audio switch tra cuffie e speaker
  Per potere usare delle cuffie tramite jack bisogna aggiungere le seguenti linee in /etc/modprobe.d/alsa.conf

  Code: Select all

  options snd-hda-intel single_cmd=1
  options snd-hda-intel probe_mask=1
  options snd-hda-intel model=generic

  Cosi' facendo si ha ora la possibilita' di attaccare e staccare le cuffie al jack senza che l'audio smetta di funzionare (sembrerebbe che con questo metodo non riconosca il microfono).
