I have this same bug with the invisible progress bars. I'm running Edgy on a Dell Optiplex GX110 (xorg.conf attached). Using Human theme, though switching themes does not fix it.
The progress bars were colored in when I first installed, but got messed up in the next few days as I installed new apps and performed tweaks (sorry, not sure what I did immediately before). Nothing in ~/.xsession- errors looks like it would be related to this. ** Attachment added: "xorg.conf" http://librarian.launchpad.net/5668346/xorg.conf -- Progress bar is invisible https://launchpad.net/bugs/67443 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
