Opening an application on a specific monitor and a specific workspace

Hi guys,

I tried to create a couple of commands that open Thunderbird maximized on the left monitor on the default workspace. They worked however those look like a bit cumbersome and I wonder if I can improve the commands.

The panel launcher from the left monitor uses this command:

sh -c '/usr/bin/thunderbird & sleep 3 && wmctrl -r thunderbird -t 0 | wmctrl -r thunderbird -b add,maximized_vert,maximized_horz'

The panel launcher from the right monitor uses this other command:

sh -c '/usr/bin/thunderbird & sleep 3 && wmctrl -r thunderbird -b remove,maximized_vert,maximized_horz && wmctrl -r thunderbird -t 0 | wmctrl -r thunderbird -e "0,290,0,-1,-1" && sleep 1 && wmctrl -r thunderbird -b add,maximized_vert,maximized_horz'

Especially the latter looks like very amateur... What do you think?

Thanks,

D.

Can you install Gdevilspie? It's a GUI for devilspie2 that (I heard) makes those operations easier to achieve.

Re: Opening an application on a specific monitor and a specific workspace

The problem I have with devilspie it is because I don't want a daemon running in background just to open a bunch a of programs in certain way, many WMs have those features by default, XFCE should provide the same features as well...

No, that is a GUI for devilspie (without the 2) - I am the developer of devilspie2 (and neither 1 or 2 is under development any longer unfortunately). I don't know of any similar GUI tool for devilspie2.

Re: Opening an application on a specific monitor and a specific workspace

I use the same approach with wmctrl with one difference: I made a script my_windows_move which moves windows. Script itself is:

#!/bin/bash
# Move working windows into its correct desktops

# Input file - SRC data
inpf=~/bin/$(basename $0).input

while IFS='' read -r line || [[ -n "$line" ]]; do
  #echo "Text read from file: $line"
  #desknum=$(echo $line| sed -r 's/^([0-9]+) .*$/\1/')
  #echo "Desknum: $desknum"
  
  # Pattern for correct input line
  pat="^[0-9]+ .+"
  if [[ $line =~ $pat ]]; then
    desknum=$(echo $line| sed -r 's/^([0-9]+) .*$/\1/')
    title=$(echo $line| sed -r 's/^[0-9]+ (.+)$/\1/')
    echo "Desknum: $desknum, title: $title"

    # Get title id from title substring
    tid=$(wmctrl -l | grep "$title" | cut -d ' ' -f1)
    for n in $tid ; do
      echo "Found id: $n, moving..."
      wmctrl -i -r $n -t $desknum
    done
  fi
done < "$inpf"

and this script reads data from a config file with the same name as the script + ".input" my_windows_move.input. The input file looks like this:

# Configuration file for my_windows_move
# Format:
#  desktop_number window_substring
#
# window_substring - can have non backslashed spaces
#
# desktop_number in wmctrl:
#      0 | 1 | 2
#      ---------
#      3 | 4 | 5
#

5 Thunderbird
3 SSL/SSH VNC Viewer
1 gFTP

I have another script which runs all applications I use most of days (the 3 above are just an example) and once all of them are running (some of them need me to type a password) I click on a shortcut and move windows into desired desktops.
For your purpose there would be necessary to add reading and using position coordinates of windows... Something like this I use only for Firefox and Vivaldi - I am bothered by the fact that XFCE can open many Thunar windows on proper desktops and positions, but it is not able to do the same with FireFox and Vivaldi (which is probably the applications fault). So I made another script, which I call before logout (I made a button which calls my personal logout script and then it makes shutdown/logout/reboot):

windows_positions --save

and the next day, after Firefox and Vivaldi are started:

windows_positions --restore

and the script windows_positions itself:

#!/bin/bash
# Move working windows into its correct places

usage="Usage: $(basename "$0") operation\n Operations:\
\n   --save     - saves windows position\
\n   --restore  - restores windows position"
operation=$1;[ -z "$operation" ] && echo -e "$usage" && exit 0

# Basic configuration 
#
# Config file - same filename as current script name
cfgdir=~/.config/$(basename "$0")
cfg=$cfgdir/$(basename "$0").cfg
cfgt=$cfg.tmp
hostname=$(hostname)

# Array of applications to be saved (exact class, not only substring)
applications=("Navigator.Firefox" "vivaldi-stable.Vivaldi-stable")

# Diff between save and restore positions via wmctrl (what the hell???)
# (subtract diff before restoration)
diff_x=10
diff_y=44

# End of basic configuration

It is not perfect but it works well with pages which does not change title before --save and --restore.

These scripts are probably just for inspiration and probably not sufficient for your purpose.

Another approach could be a script which could read info from ~/.cache/sessions/xfwm4-*.state and restore windows according saved session info...
