Same bug here. Using Ubuntu 13.04 (64 bit) with GNOME Shell
When you try to connect to a network which requires certificate, it will display a dialog titled "No Certificate Authority Certificate chosen". That window can't be clicked, neither using the mouse nor using the keyboard, so you can't connect to the internet. This is a screenshot: http://img443.imageshack.us/img443/2443/schermatadel20130430095.png Also that bug there isn't if you are using Unity instead of GNOME Shell. I hope this can help.. best regards, -- Shin -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1168293 Title: "No Certificate" dialog not responding To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1168293/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
