I tried to put my LMDE (201108 RC of both types) to have login automatically to user account.
1. Installed fresh LMDE (and updated all packages, now up to date) (HD got broken
2. created normal user (yyy)
3. locked in and out as normal (yyy) user (to make sure it exists)
4. re-started PC and locked in as main user (xxxadmin)
5. Started "Login Screen Settings" and tried to activate editing from "lock". Nothing happens.
(everything else seems OK in my favorate system)
Same "feature" in both editions
Bug or newbee issue
(was working on my 201012 edition, last update 2Ms back)...
If bug, I hope will be corrected before official release.
