Posted by cviorel on May 6, 2009 No comments | This post has 562 views.

I use the following script to automatically update my Ubuntu box.
I don’t recommend using this on your production servers!

Apply themes to GTK apps running as root

Posted by cviorel on April 13, 2009 No comments | This post has 798 views.

To make your current installed themes available to the root account as well, you just need to run these in your terminal:

sudo ln -s ~/.themes /root/.themes
sudo ln -s ~/.icons /root/.icons
sudo ln -s ~/.fonts /root/.fonts

sudo ln -s ~/.fonts /root/.fonts
