I want to change my network monitor applet to this icon.Currently my network monitor applet has this icon .I am using ubuntu 10.04,how to do this?
There is a very simple way to do what you wish without root privileges or even overwriting anything. As you know, your icon themes are located in /usr/share/icons. Simply go to your icon theme directory and locate the icon(s) you wish to replace, taking note of their locations.
In your home folder there is a hidden directory called .icons. In Nautilus you can hit Ctrl+H to see it. Any icons you put in this directory will be treated as icons are treated in /usr/share/icons. The only catch is that icons places in the .icons folder available only for that user. Also programs run as superuser, like Synaptic, will not reflect any changes in theme-ing added to your home folder.
A way to solve that is to symbolically link ~/.icons (and ~/.themes if you want) to the corresponding folders in /root.
If you wanted to do that you could put this in terminal:
That will make your user themes globally available without needing root privileges at all. But that's beyond the scope of the question and I'm babbling.
I will use the Mint-X icon theme and the application Blender as an example.
Now instead of the Blender icon in /usr/share/icons/Mint-X/apps/48 I see the one in ~/.icons/Mint-X/apps/48 used in apps and menus that use the 48x48 sized Blender icon.
Keep in mind that everything is case sensitive and must match each other exactly for this trick to work!
There a few other ways to do this without overwriting anything in an icon theme, but this is by far the simplest. Also, just putting your custom icon in ~/.icons often works (the Twitter client Hotot is an example).
I recommend learning what the index.theme files do. Those files control what places your system looks to decide which icons to use, what to name the theme, etc. Open one up in Gedit and have a look, it's pretty simple!
The way I do it is by keeping a custom theme in ~/.icons that I always use (to make sure panel icons are the correct colors, mostly). I make up an index.theme file (you can copy one rather than write a whole new one, but make sure your folder locations correlate!) and just have it "inherit" the new theme I want.
So if I wanted to use the Elementary icon theme instead of the Faenza-Dark one I would change the line
So in turn, by inheriting Elementary I will also inherit whatever Elementary inherits, but my icons will always come first.
Hope that was helpful, time for bed!
This helped me:
Hope it works out for you.
The icon name in use there is the 'network-transmit-receive' .
So what you need to do is, Name your favorite icon as 'network-transmit-receive.png'/'network-transmit-receive.svg' depending on what format you have in your theme. Either replace it or just add one if your theme does not have the 'network-transmit-receive' icon.
Other icon names used, at times, in the applet are the "network-idle", "network-receive", "network-transmit" .
