I’m presenting another quick tip I’ve just found out while browsing the web (thanks google) which is making my GNOME panel go transparent (as in 100% transparent, including the indicator applets). The source of the tip is to be found here. Ok so there we go:
Open Ambiance or Radiance gtkrc file with this command from a terminal window:
sudo nano /usr/share/themes/Ambiance/gtk-2.0/gtkrc
Scroll down until you find the following line:
bg_pixmap[NORMAL] = "panel_bg.png"
Comment it (put a # in front of the damn line), save the file and then you can either go to Appearance Properties and change to another theme then switch back to Ambiance (or Radiance) or logout then login back again.
Have fun y’all! 😀
P.S.: If you want to apply the settings locally you can copy the directory Ambiance from /usr/share/themes/Ambiance/ into your home directory ~/. Here’s how to do it in case you are clueless:
cp /usr/share/themes/Ambiance/ ~/
You might as well use the file browser. Ok, that’s it for now. See you soon!
