Arch on laptop (Dell XPS 15 9530)


System/Performance:

[code]

Install bumblebee + nvidia/intel drivers

Install tlp + configure it -> http://files.bestmail.ws/Arch/setup/tlp.txt

Enabe SSD Trim (systemctl enable fstrim.timer)

Change I/O scheduler to noop -> sudo nano /etc/udev/rules.d/60-schedulers.rules:
# set noop scheduler for non-rotating disks
ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="0", ATTR{queue/scheduler}="noop"
# set bfq scheduler for rotating disks
ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="1", ATTR{queue/scheduler}="cfg" 

Optimize mirrorlist with "syu" ( /home/bin/syu ) -> http://files.bestmail.ws/Arch/setup/bin/

Install intel-ucode + update grub config

Install lm_sensors + run sensors-detect -> Install thermald afterwards + enable thermald.service

dnscrypt + dnsmasq (enable dns caching) -> cisco (opendns) as server ?

ToDo:

[code]

Add SSH-Tunnels to encrypt browser/mail/sensitive traffic instead of complete system traffic (no encryption for games plz)

Add linux-grsec kernel + pax

Add multi-display-support (for 120Hz output via displayport)

Add DAC driver for my Sennheiser HD600

Add virtualbox or similiar

Configure firejail even more

Find any decent skin for audacious (winamp is ugly) or switch to Deadbeef :( .. missing foobar !

[/code]


What else I can do to optimize my arch laptop?

Is there anything I can improve, should change or add ? Especially in the system/performance part?

Is there anything I can do to make my laptop more bulletproof as daily driver for work,home,everything ?

Are my configurations fine so far or e.g. is powertop + tlp an overkill ?

Any general advice for my next steps?
