Having the same issue here on Lenovo T420s with Xubuntu 14.10. After closing the lid or sleep upon resume the lock screen is displayed as intended. After having entered the password the screen blanks and stays that way. Binding xrandr --auto to a shortcut works but is an ugly workaround.
Is there no possability to fix or automate the workaround and having a working resume process?
