Is there a way to make Chrome/Chromium's notifications use notify-osd instead of the ugly boxes it uses by default?
This can be installed from the Google Chrome Web Store.
To install it, just go to the webstore and click the "Add to Chrome" button - it'll do the rest.
To use it, you'll probably need to restart Chrome, at that point it should be working.
Once you have installed it in Chrome, Click on the Wrench Icon, then select the Prefences Menu, then Extensions and you should see:
The Chromify-OSD extension Icon and that it is enabled. The extension is now installed and enabled.
The only other requirement to make this work is that you have the notify-osd packages installed in your system or this will not do anything at all.
HTH. Have a nice day. :)
