Comment 11 for bug 546785

I have additional information.

In the login window, 'gdm', selecting a different keyboard layout changes your .dmrc file for that session.

For example, if choose Spanish, then the 'layout' option inside .dmrc file is changed to spanish, which is great.

If we choose 'USA', which is by default in english installations of ubuntu, from the layout menu at 'gdm', then the 'layout' option under your .dmrc file shows 'us'.

So, not only changing keyboard layout in control-center should update default gdm layout in .dmrc. Something needs to be done to avoid 'gdm' to overwrite users' .dmrc 'layout' option (if previously established under control-center).

Cheers,
