Custom icon for terminal application in gnome-shell
March 25, 2018
Recently I wanted to create separated “window” for my weechat so I can easily alt-tab to it.
I’ve wrote the .desktop file and place it to
gnome-shell (I’m on ubuntu 17.10) will show me it.
And it did, BUT when I start the weechat the icon turned to “terminal-like”.
play with terminal icon
Ok, there is terminals like
xfce4-terminal that allows to set custom icon
when terminal is starting… so let’s try
xfce4-terminal -I /the/icon/i/need -e /usr/bin/weechat
There are other temrinals allows us to set custom icon but non of them was working.
It turned out the gnome-shell overrides everything it thinks is a terminal with the icon from theme currently used.
Discarding some guesses I decided that gnome-shell determines that app belongs to “terminal family” based on WM_CLASS
window property (you can see them using
xprop). Thanks god (or gnome developers) the gnome-terminal has
that overrides the WM_CLASS property. After that my .desktop file just works.
