xserver-xorg-ati does not reactivate monitor after hibernate

[Shawn H Corey]

I'm running Linux Mint 17.2 with a Radeon HD 5770 card. When I restart
the computer after hibernating, the monitor remains in low-energy mode.
That means it is not receiving a signal from the card.

I have tried pressing Ctrl+Alt+Del, which should bring up the Quit
dialog with the Shutdown button as focus. And sure enough, after I
press RETURN, the computer shuts down.

I have also tried Ctrl+Alt+F1 but the monitor remains off. If I type
blindly, I can log in and enter `sudo shutdown -r now` and sure enough,
the computer reboots.

Everything seems to be working but the monitor signal. What can I do to
fix this?
