Comment 36 for bug 396226

Ramon:
Are you sure that it's the same bug? I'm in the same position as you, I'm testing the proprietary drivers, but for me it's not a timed issue neither is it with completely random characters. I always get logged out when I'm entering my password for the wireless network, specifically when typing @. When I log in again it works without problems. I've filed a new bug here: https://bugs.launchpad.net/ubuntu/+source/gnome-desktop/+bug/522554
