Peace, Love and C++

For the sake of anyone else who’s fighting their screens, I’ve got a script that will do this (but very very slowly)

setup script

xrandr --output VGA1  --auto
xrandr --output LVDS1 --auto
xrandr --output VGA1  --rotate left
eval "`monconf`"

monoconf script

#!/usr/bin/env python
import subprocess
output = subprocess.check_output(["/home/tag/.bin/mon.ls"])
output = [ item.split() for item in output.split("\n") ]

mons = {}

for mon in output:
    if len(mon) > 0:
        if mon[1] == "connected":
            res=mon[2]
            res=res.split("x")
            for item in res[1].split("+"):
                res.append(item)
            res.pop(1)
            mons[mon[0]] = res

BOTTOM_LEFT = "LVDS1"
TOP_RIGHT="VGA1"

LEFT_WIDTH  = mons[BOTTOM_LEFT][0]
LEFT_HEIGHT = mons[BOTTOM_LEFT][1]

RIGHT_WIDTH  = mons[TOP_RIGHT][0]
RIGHT_HEIGHT = mons[TOP_RIGHT][1]

print "xrandr --output %s --pos 0x%s" % (
    BOTTOM_LEFT,
    (int(RIGHT_HEIGHT) - int(LEFT_HEIGHT)))
print "xrandr --output %s --pos %sx0" % (
    TOP_RIGHT,
    int(LEFT_WIDTH)
)

and the mon.ls command

xrandr -q | grep "^[^\ ].*" | grep -v Screen

All of this is super hacky, but it works.
