I3 Community Edition starts with green/purple lines on the screen

It can be fixed if I plug it into an external monitor and run xrandr --auto which then allows me to use the laptop on the external monitor. Ideally I would like to fix this issue, and then extend the screen if it connects to the monitor.

I have the same issue when I get to the login screen.

My default resolution is 3000x2000.
After I entered my password and changed my display resolution to 1920x1200 everything seems to be fine.

Here are some specs that might be useful.

I’ve found a solution (or at least a workaround):

  1. Identify your internal display
    grep "\<connected\>"< <(xrandr)
    [mrvn@mmo-mtbk ~]$ grep "\<connected\>"< <(xrandr)
    1: eDP1 connected (normal left inverted right x axis y axis)
    2: DP1 connected primary 3440x1440+0+0 (normal left inverted right x axis y axis) 800mm x 330mm
    [mrvn@mmo-mtbk ~]$
    
    In my case, (1) is my internal monitor and (2) is my external monitor. So I remember eDP1 as my internal display.
  2. Gather information about the resolution you want to use after booting the OS
    cvt 1920 1200 60 #(change values to fit your needs)
    This will output the modeline for using the resolution 1920x1200@60Hz
    In my case:
    Modeline "1920x1200_60.00"  193.25  1920 2056 2256 2592  1200 1203 1209 1245 -hsync +vsync
    
  3. Create a file named 10-monitor.conf under /etc/X11/xorg.conf.d/ and paste those lines:
    Section "Monitor"
        Identifier "eDP1"
        Modeline "1920x1200_60"  193.25  1920 2056 2256 2592  1200 1203 1209 1245 -hsync +vsync
        Option "PreferredMode" "1920x1200_60"
    EndSection
    

That is a problem when monitors are constantly pushed and pushed - an aspect ratio of 3:2 is like the old 4:3 ratio vga (800x600) svga (1024x768) and is bound to create problems when everything is created to 16:9 hd (1366x768) fhd (1920x1080) - even 16:10 fells awkward.

You’re right.
That’s why I chose to use 16:10 instead of 3:2.
So far, I’ve never had those green/purple lines on laptops with native 16:9 or 16:10.

Well, I’m happy enough that it is working now.

My solution ended up being changing my driver from intel to modesetting in xorg.conf.

Section "Device"
	Identifier  "Card0"
	Driver      "modesetting" # used to be "intel"
	BusID       "PCI:0:2:0"
EndSection
