# The default configuration file exists at /etc/libinput-gestures.conf

Install Notes - Dell XPS 13 (9370) 2018

The laptop works well on Archlinux. A few notes based on the installation guide for the previous version.

Intel GPU Power Saving

Per the Arch wiki, more power can be saved by creating /etc/modprobe.d/i915.confwith the following content:

options i915 modeset=1 enable_rc6=1 enable_fbc=1 enable_guc_loading=1 enable_guc_submission=1 enable_psr=1

  echo >&2 ERROR: Commit message must include issue number.
  exit 1

exit 0

How to make faster scroll effects?

• Avoid too many reflows (the browser to recalculate everything)
• Use advanced CSS3 for graphic card rendering
• Precalculate sizes and positions

Beware of reflows

The reflow appens as many times as there are frames per seconds. It recalculate all positions that change in order to diplay them. Basically, when you scroll you execute a function where you move things between two reflows. But there are functions that triggers reflows such as jQuery offset, scroll... So there are two things to take care about when you dynamically change objects in javascript to avoid too many reflows:

var auth_token = $("input[name='authenticity_token']")[0].value; 
$("a.repo-name[href^='/THEORG']").each(function($elem){ 
    $.post("/notifications/subscribe", { 
        authenticity_token : auth_token, 
        do : 'included', 
        'repository_id' : $("form.js-unsubscribe-form #repository_id", $(this).parent("li")).val() 
    }); 
});

// CSS Color Names
// Compiled by @bobspace.

// A javascript object containing all of the color names listed in the CSS Spec.
// This used to be a big array, but the hex values are useful too, so now it's an object.
// If you need the names as an array use Object.keys, but you already knew that!
