I have a behaviour very similar to
https://bugs.freedesktop.org/show_bug.cgi?id=42960.
After resuming from suspend, display is blank.
I have tried the tricks suggested in #42960 (acpi_sleep=s3_bios) with no luck,
when I use that the laptop doesn't resume correctly.
With the catalyst driver the display resumes correctly.
It's an Ubuntu 13.10 with a 3.14 kernel, DPM is activated.
Feel free to ask for tests.
