dtoggle
=======
Small bash script that uses `xrandr` to configure internal/external displays. I use it here with Arch Linux and i3 whenever I connect one or more external displays.
I use the toggle option with the `XF86Display` key (Fn + F7) on my Thinkpad:
```
bindsym XF86Display exec "~/Documents/bin/dtoogle -p home -t"
```
Config File
-----------
dtoogle can read the to be used profile from a config file in `$HOME/.dtoggle.conf`. If the config file is not present you have to specify the profile using the -p option. The file looks as follows:
```
# Set your desired profile here
PROFILE=home
```
Command Line Options
--------------------
```
dtoogle [-ceix] [-hmntv] [-lr] -p profile
Display Options:
-c Clone screen on all displays
-e Enable external display(s) and disable internal
-i Enable only the internal display
-x Extend screen to all displays [default]
General Options:
-h Show this help
-m Show all available modes
-n Dry run. Do not run xrand. Implies -v
-t Toggle different options"
-v Be more verbose
Position:
-l Display n is left of display (n+1)
-r Display n is right of display (n+1) [default]
Profile:
-p profile Enable the specified profile
```
Usage
-----
1. Clone the repository and copy dtoogle to a location in your `$PATH`
2. Open the file in a text editor, look for the `choose_profile()` function and change the profiles to your needs or add new ones. I included my profiles for home, work and projector. In order to get the names of the displays, connect them and run `dtoogle -m`. Look for the strings that say "connected". Add the name of your internal display to `INTERN` and all names of your external displays to `EXTERN[0]` up to `EXTERN[n]`. Note: The order of the extries is important, i.e. entry number n is either left of right (depending on the option) of number (n+1)!
```bash
function choose_profile()
{
[...]
case "$PROFILE" in
# Home profile: Internal on, external extended
home)
INTERN="LVDS1"
EXTERN[0]="HDMI1"
;;
[...]
# -----------------------------------------------------------------------
# Add your own profiles here.
# -----------------------------------------------------------------------
# name)
# INTERN="LVDS1"
# EXTERN[0]="VGA1"
# ...
# EXTERN[n]="VGAn"
# ;;
# -----------------------------------------------------------------------
```
3. Check the command line options with `dtoogle -h` and enjoy.
