Font colours on the login screen menus
On my login screen, if I try to change, for example session, the font on the menu that appears is the same colour as the background. This makes it impossible to see the options available.
Can anyone point me in the right direction as to where I can change the font colours. I have changed the GDM theme thinking that was the answer but I get the feeling that the menu fonts on the login screen are not part of the GDM theme.
Any tips would be gratefully received.
I'm running Gnome on Ubuntu Dapper.
