ThinkPad T420 after installing arch what files are important?

Hello community

installing arch in now not a problem for me

i read the wiki but iam not sure what are importand configs and what not. So my question is what configs must i have or create.

does anybody has the same Laptop ThinkPad T420?

specs i5 with integrated HD 3000,16 GB RAM,256 GB SSD M4 Cruicial.

do i need this?

CPU Frequency Scaling
CPU frequency scaling is fully supported with all of the available processor models with this laptop.
Fans
The thinkpad_acpi kernel module needs to be configured so user space programs can control the fan speed.
/etc/modprobe.d/modprobe.conf
options thinkpad_acpi fan_control=1
The thinkfan configuration file also needs to know how to set the fan speed. Replace the default sensor settings with the following.
/etc/thinkfan.conf
sensor /sys/devices/virtual/thermal/thermal_zone0/temp
You can add or remove services by editing the DAEMONS array in your /etc/rc.conf file. It will initially look something like this:
DAEMONS=(...@thinkfan...)

Synaptics
TouchPad and TrackPoint do work out of the box, but the TouchPad is way too sensitive (i.e. fast) to be usable, since it is recognized as a mouse. To fix this, install the xf86-input-synaptics package and add the following two files to your /etc/X11/xorg.conf.d/ directory:
50-thinkpad-trackpoint.conf
 Section "InputClass"
        Identifier      "ThinkPad TrackPoint"
        MatchProduct    "TPPS/2 IBM TrackPoint"
        MatchDevicePath "/dev/input/event*"
        Option          "EmulateWheel"          "true"
        Option          "EmulateWheelButton"    "2"
        Option          "XAxisMapping"          "6 7"
        Option          "YAxisMapping"          "4 5"
 EndSection
50-twofingerscroll.conf
 Section "InputClass"
        Identifier      "two finger scrolling"
        Driver          "synaptics"
        MatchProduct    "SynPS/2 Synaptics TouchPad"
        MatchDevicePath "/dev/input/event*"
        Option          "VertTwoFingerScroll"   "on"
        Option          "HorizTwoFingerScroll"  "on"
        Option          "EmulateTwoFingerMinW"  "8"
        Option          "EmulateTwoFingerMinZ"  "40"
        Option          "TapButton1"            "1"
 EndSection

Optional kernel boot arguments
Using the following kernel boot parameters [drastically reduces battery drain]:
pcie_aspm=force
i915.i915_enable_rc6=1
i915.i915_enable_fbc=1
i915.lvds_downclock=1 

i dont't know what else is importand so i hope someone has the same laptop as i and can type me all configs that are important to change,or to create, and what programs are needed

thank you

Re: ThinkPad T420 after installing arch what files are important?

The wiki entry is written by 'someone who has the same laptop' and covers most things you want to know.
https://wiki.archlinux.org/index.php/Le … nkPad_T420
Please do not ask a generic question about what you need. Instead choose what you want first, and come back if you can not achieve it on your own using the wiki and forum search.
Also nobody can tell you what programs you want, you have to decide on your own in arch linux.
