[SOLVED]Some application do not have specific icons

Hi,

I use a lot of rdesktop and Xephyr windows but neither have an icon, so it's hard to select the correct window by clicking on the right icon/ or by selecting goog icon via alt-tab

I would like to change dynamically the icon for the just launched app, examples :

to launch a desktop session on my server's virtual machine "vm1" i use this script :

export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/lib/x86_64-linux-gnu/
Xephyr -title xephyrvm1 -ac -screen 1680x1050 -br -reset -terminate 2> /dev/null :1 &
sleep 1
wmctrl -i -r $(wmctrl -l |grep xephyrvm1|cut -f1 -d" ") -b toggle,fullscreen
DISPLAY=:1.0 ssh -XfC user@xephyrvm1  gnome-session --failsafe

i would like to associate the window's icon with ~/Documents/ICONS/vm1.png

is it possible ?

Re: [SOLVED]Some application do not have specific icons

You can use xseticon to change that icon. Be careful though, there are 2 versions of xseticon and I can't get the newer version to work. The one I linked above does work. You may need to build it from source though if your repositories don't carry it.

This is the template executable file that I dump into /usr/local/bin:

#!/bin/bash

### EDIT THESE VALUES #########################################################
APP="/full/path/to/real/executable"       # path to real executable
ICON="/full/path/to/png/icon"    	  # icon file - only png supported
WAIT=2                			  # wait time for application window to display - adjust to suit
###############################################################################

###############################################################################
### DON'T CHANGE ANYTHING BELOW
###############################################################################
function change-panel-icon {

    sleep $WAIT
    activeWinLine=$(xprop -root | grep "_NET_ACTIVE_WINDOW(WINDOW)")
    activeWinId="${activeWinLine:40}"

    xseticon -id "$activeWinId" "$ICON"
}

$APP & change-panel-icon

I adapted it to get xephyr to startup as per your commands:

#!/bin/bash

### EDIT THESE VALUES #########################################################
APP="Xephyr -title xephyrvm1 -ac -screen 1680x1050 -br -reset -terminate"
ICON="/usr/local/share/xephyr.png"    	
WAIT=1                			
###############################################################################

###############################################################################
### DON'T CHANGE ANYTHING BELOW
###############################################################################
function change-panel-icon {

    sleep $WAIT
    activeWinLine=$(xprop -root | grep "_NET_ACTIVE_WINDOW(WINDOW)")
    activeWinId="${activeWinLine:40}"

    xseticon -id "$activeWinId" "$ICON"
}

$APP 2> /dev/null :1 &
change-panel-icon

I had to change a few things, but it worked for me - brought up the xephyr window with the new icon. I wasn't able to test the ssh connection part of your command, but you should be able to add it to the end and it should work.

Re: [SOLVED]Some application do not have specific icons

Just tried this on my Xubuntu 16.04 install and it got tricky with getting xseticon installed. Its no longer available in the repositories and it will not compile. What did work was the following:

1. Dowload the xseticon deb file from http://packages.leonerd.org.uk/pool/main/x/xseticon/. Make sure you get the correct one for your architecture (amd64 or i386).

2. Extract the xseticon executable from that deb file and place it in /usr/local/bin.

3. Run the following command to make the libgd library backwards compatible and resolvable to the version 2 library:

sudo ln -s /usr/lib/$(uname -m)-linux-gnu/libgd.so.3.0.0 /usr/lib/$(uname -m)-linux-gnu/libgd.so.2

Then it should work.

Re: [SOLVED]Some application do not have specific icons

hello ToZ and thanks a lot for the answer !

i got it to work, but your xprop command can't get correctly the window id of my apps, but as i already had it, i modified my script for now with :

export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/lib/x86_64-linux-gnu/
Xephyr -title xephyrvm1 -ac -screen 1680x1050 -br -reset -terminate 2> /dev/null :1 &
ICON=<path to png icon>
window_id=$(wmctrl -l |grep xephyrvm1|cut -f1 -d" ") 
wmctrl -i -r $window_id -b toggle,fullscreen
xseticon  -id $window_id $ICON

now there is my tasklist :

with a win7 icon, a suse11 icon and a suse12 icon ! the alt-tab shows icons too, so i'm so happy

so neat ! thanks a lot ToZ

i will cross post this in a xubuntu forum
