The documentation linked above about how to enable onboard at GDM was written for the old GDM. Since karmic, Ubuntu is shipping the new GDM that offers an accessibility icon to open the accessibility dialog which contains a checkbox to start the onscreen keyboard.

These files need some updating, as they don't include some features added to onboard the last years. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/768602 Title: Does not contain any a11y/tablet computer documentation about Onboard, the default on-screen keyboard -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
