I'm having the same error on Ubuntu 16.04.1 LTS (4.4.0-59-generic, 64bit) with ATI RV570 [Radeon X1950 PRO]: if logged in or locked, after the screen is turned off due to the inactivity time set in Ubuntu, it can not be turned back on by hitting a key / moving the mouse. It has to be rebooted manually. The error does not occur, if there is no logged-in user.
