Display not powering up after resume

Hi,
I have an Asus 55DR-SX138H laptop, here are the complete hardware specifications: http://goo.gl/s3ie8a.
Suspension is not fully working: after resume, the display remains switched off. I can confirm that the OS returns 'active', because I can use the combination 'CTRL+ALT+FN' to switch console and type in the reboot command, and it works! How could I solve this? Probably it's related to the fact my laptop has dual-graphics:

lspci | grep VGA
00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Trinity [Radeon HD 7640G]
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Seymour [Radeon HD 6400M/7400M Series] (rev ff)

Thanks in advance for helping..
