just as the name says, this is a bit of my xinitrc file as used in a dual monitor evilwm setup.

a little about my setup:
Gentoo
evilwm (emerge x11-wm/evilwm)
SLiM Simple Login Manager (emerge x11-misc/slim)
conky lightweight system monitor (emerge app-admin/conky)

so when i first started using evilwm in a dual monitor setup i realized that i could not drag windows across monitors, which in all reality turned out to be awesome since it made me focus on how to properly optimize my setup for work.

so first thing i did was changed my slim.conf to start my xinitrc from /etx/X11/xinitrc/xinitrc since i am the only user of this machine and since i dont log in as root.

line from slim.conf to call xinitrc:

login_cmd               exec /bin/bash -login /etc/X11/xinit/xinitrc

this could be changed to start a local xinitrc (~/.xinitrc) but whatever, thats up to the user.

now, the xinitrc file has all my basic stuff starting on each respective monitor. to find out which monitor is which just run xrandr (emerge x11-apps/xrandr or grab it from xorg)

here is output from xrandr monitor 0.0 (right):

and here is a snippet from my xinitrc file:

        /usr/bin/evilwm -snap 10 &
        xsetroot -solid \#000000 -cursor_name crosshair -display :0.0
        xsetroot -solid \#000000 -cursor_name crosshair -display :0.1
        conky --display=:0.1 &
        trayer --expand true --transparent true  --alpha 255 --edge bottom --align right --expand true --SetDockType true --widthtype request --margin 130 --display=:0.0 &
        setxkbmap -option terminate:ctrl_alt_bksp
        xbindkeys &
        DISPLAY=:0.0 /bin/bash scripts/work/random_images.sh &
        DISPLAY=:0.1 /bin/bash scripts/work/random_images.sh &


ill try to explain it line by line:
/usr/bin/evilwm -snap 10 & starts evilwm with a snap size of 10px

xsetroot -solid \#000000 -cursor_name crosshair -display :0.0
xsetroot -solid \#000000 -cursor_name crosshair -display :0.1
sets the background color and crosshairs per monitor (xsetroot cursors covered in a previous post)

conky --display=:0.1 &starts conky on my left monitor (conkyrc as described in previous posts)

trayer --expand true --transparent true --alpha 255 --edge bottom --align right --expand true --SetDockType true --widthtype request --margin 130 --display=:0.0 & starts my doc tray to minimize certain programs on the right monitor (emerge x11-misc/trayer)

setxkbmap -option terminate:ctrl_alt_bkspsets my ctrl alt del to restart evilwm (xorg)

xbindkeys & starts xbindkeys (x11-misc/xbindkeys) which launches gmrun (x11-misc/gmrun) bound to alt f2

DISPLAY=:0.0 /bin/bash scripts/work/random_images.sh &
DISPLAY=:0.1 /bin/bash scripts/work/random_images.sh &
using the DISPLAY variable to call my wallpaper scripts (from previous posts) per monitor

so with all this done, now when i log in i can just start any other misc programs that i need with my environment all set up.
