Linux: 1080p external screen desktop only covers a quarter screen [Using xrandr]

I used to use Ubuntu for my development environment, since I have a new workstation that I have decided to switch to Manjaro, with a KDE GUI.

When I used Gnome, I used a tool called xrandr-extend to give me the ability to use both the 4k screen of my laptop and my external 1080p screen without suffering from the usual scaling problems. It works well; I had no problems with xrandr-extend in Gnome. In Manjaro, however, I have a problem that I cannot solve.

The problem lies in the desktop on the external screen:

Desk with external display

As you can see, three quarters of the screen are black, while the desk accommodates the last quarter of the screen.

I think it may have something to do with the fact that I am compressing the screen by 2 in the xrandr-extend configuration. I am doing this to achieve the optimum degree of scale to use applications on the screen. However, if this is the case, how can I maintain the level of scale that I need while the entire desktop instance on the external screen covers the entire width and length of that screen?

To my knowledge, I have filled in the configuration file correctly: 

[provider:modesetting]
primary = eDP-1
hdmi = HDMI-1
vga = DP-1

[provider:nouveau]
primary = eDP1
hdmi = HDMI1
vga = DP1

[resolutions]
primary = 3840, 2180
hdmi = 1920, 1080
vga = 1920, 1200

[scaling]
hdmi =  2

The console logs generated when I execute the command to extend and scale the external screen:

[dukejm@duke-pc ~]$ xrandr-extend -n hdmi                 
xrandr --auto
xrandr --listmonitors
xrandr --output eDP1 --auto --output HDMI1 --auto --panning 3840x2160+3840+0 --scale 2.0x2.0 --right-of eDP1

dnd 3.5e – Is there a rule that covers self-made equipment as a starter equipment at higher levels?

The rules expressly allow initial magical objects to be initiated at higher levels.

Dungeon Master & # 39; s Guide (3.5) p.199 gives the official rules for starting a new character above the 1st level. The most relevant section is under Magic Items as Equipment:

Magic objects created by characters: A PC spell caster created at a level higher than the first level can use any of the XP and GPs you have granted to make magic items, provided it has the exploits and prerequisites for creating objects.

However, advice is also provided on what elements to allow, with particular guidance on how to prevent PCs from spending all their initial wealth with a dominated element.

You are free to limit what magical items characters can choose when they create characters from higher levels, as if you were assigning those items to treasures accumulated in the game. You can exercise a veto item by item, but an easier method is to use a maximum cost for a single item as a limit. (…) You can also limit the characters to a certain type of magic item.

Set cover with several covers

In the Set Cover problem we need to cover each item at least once.
I am considering the case in which I want each item to be covered at least $ k $ times with constant $ k $.

I consider the classic LP for the problem and random rounding.
Is it true that the modification of the LP of $ geq 1 $ to $ geq k $ in the coverage restriction and with the same rounding (up to the number of repetitions) also works well for this variant?

It seems so, but I'm not sure if I'm missing something.

Algorithms – Practical calculation of disjoint vertex cycle covers of minimum weight

How are the vertex-disjoint cycle covers of minimum weight of large dense symmetric graphs in real implementations really calculated?

I know that the problem can be reduced to a general coincidence using the Tutte device or the device suggested by Lovasz and Plummer; However, there is a fly in the ointment with those reductions, namely that each vertex of the original graphic is replicated $ O (n) $ times, producing a match problem for a chart with $ O (n ^ 2) $ vertices and therefore a $ O (n ^ 6) $ algorithmic solution

Question:

These are the devices actually used to calculate the lightest D factors and especially the 2 factors or, if the linear programming formulation provides significantly better performance, resp. footprint and, if so, which variant of linear programming is the most appropriate, primal, dual, primal-dual, etc.

I need an efficient way to generate those cylce covers to investigate the performance of a new idea for a heuristic TSH.

Algebraic Geometry – Covers a related variety by finely many irreducible related related subvarieties

Take a related Noetherian scheme. Can it be covered by many locally closed irreducible and related related subsystems?

An example: take the 4-dimensional related space on a field and consider the union of two interesting planes at a single point, a cover is {the foreground, the background minus a line passing through the point of intersection, the line that passes through the intersection point minus the intersection point}.

Why threads & # 039; Do the covers need moderation approval?

He noticed that when he loads a cover to his thread, it is configured to wait for approval. It would be good to eliminate that approval of moderation for the cover.

javascript: fixed navigation scrolls too far and covers the top of the content

I have a fixed browser that I created in React, but when I click on a link, the window scrolls too much and the browser covers the top of the content. I have tried to dynamically calculate the height of the navigation and take this into account in the displacement, but it still goes to the wrong position. 

import react from & # 39; react & # 39;
import {string} from & # 39; prop-types & # 39;

The FixedNav class extends React.Component {
constructor (accessories) {
super (accessories)

this.handleClick = this.handleClick.bind (this)
}

shouldComponentUpdate (nextProps) {
returns nextProps.navItems! == this.props.navItems
}

handleClick on (e) {
const nav = document.querySelector (& # 39; # fixedNav & # 39;)
we go to navHeight = nav.getBoundingClientRect (). height
leave itemLink = document.querySelector (e.target.parentElement.dataset.link)
leave scrollHeight = itemLink.offsetTop - navHeight
window.scroll (0, scrollHeight)
window.location.hash = e.target.parentElement.dataset.link
e.preventDefault ()
}

createNavItems () {
const {navItems} = this.props
returns navItems.map ((item, key) => {
const itemLink = items[1].link
he came back (
        
  • 
          
            
    { articles[0] }
    
              
        
    • 
      
      
      
      )
})
}

render () {
const navItems = this.createNavItems ()
he came back (
      
    
        
      
          
          
          
          {navItems}
        
    
      
    
    
    
    
    )

    Theory of complexity – Matrix that covers by squares.

    I wonder about the following decision problem:

    Instance: we consider a $ n times p $ matrix $ M $ of zeros and ones, and two integers. $ N $ Y $ k $.

    Question: Is it possible to cover all of the matrix with $ N $ side length squares $ k $?

    It is possible that the squares cover some of the zeros in the matrix and that they can overlap each other.

    I have the impression that it is $ textsf {NP} $-complete (it is clear $ textsf {NP} $), I find some similarities with the grid that covers rectangles, but I can not find a good reduction.

    Can I get any idea about the problem?

    Thank you.
