In Ubuntu 11.04 using Unity or Gnome Classic the same visual bug is there. The option selected for a network connection is not highlighted enough so it is very hard to know which one is selected. In the following picture you can see the example where no option appears brighter than the others so i do not know which one is the one selected in case where i want to share a connection or have several connection options available.
UPDATE - Just in case nobody noticed. The Intel* and **Auto Ethernet options can both be selected using the first card there (The Wired Intel 8255DC-2). The problem is that the Auto Ethernet does not appear highlighted or brighter than the Intel option which can also be selected with the same NIC. Do not confuse the picture with the gray options. You can even notice that the Disconnect option is the same bright white than the "Selected" option.
UPDATE2 - In the following image from Ubuntu 10.10 you can see that the highlighted connection is more BLACK than the rest. In my case, in the original theme, the option should be more WHITE than the rest.
Ubuntu 11.04 with more options to show what i mean.
As you can see in the image, the Intel connection has the same color than the Shared and Realtek ones. If i had more it would confuse more the problem since with a quick glance i would not be able to find the one used at the moment.
So what option do i need to edit to change the selected connection to a brighter color?
