Changes in window themes of something of the sort is causing the popup dialogs in Eclipse to have a very dark background. Then, since Eclipse uses hyperlinks in dialogs, I get blue on black, and it's basically unreadable. I tried changing themes in Ubuntu Tweak, but nothing seemed to affect the background color of that dialog. Can anyone help?

Eclipse can use GTK themes but it is an option, it's not obligatory. Go to Preferences, General->Appearence. Select "Classic" in Theme instead of GTK. Restart eclipse and you should be happy with the result.

Cheers :)

+1 Classic looks much better than the Gtk themes. It also fixes the problem that I can't read the heap status when "Default" is enabled. – Aaron Digulla Nov 21 '12 at 8:14

I use Kubuntu 12.10.

I fix this problem with change color of tooltips background and change color of text tooltips.

To change the colors, open "System Settings" -> "Application Appearance" -> Colors -> Colors -> "Tooltip Background" – Aaron Digulla Nov 21 '12 at 8:15

On ubuntu 12.10 (quantal) you can use the following two commands:

#foreground white => black
sudo sed -i s/tooltip_fg_color:#ffffff/tooltip_fg_color:#000000/g  /usr/share/themes/Ambiance/gtk-3.0/settings.ini /usr/share/themes/Ambiance/gtk-3.0/gtk.css /usr/share/themes/Ambiance/gtk-2.0/gtkrc
#background black => yellow
sudo sed -i s/tooltip_bg_color:#000000/tooltip_bg_color:#f5f5b5/g  /usr/share/themes/Ambiance/gtk-3.0/settings.ini /usr/share/themes/Ambiance/gtk-3.0/gtk.css /usr/share/themes/Ambiance/gtk-2.0/gtkrc

(Thanks to the other answers here that helped me to figure this out)
