@Po-Hsu, we would need more info on the system config when the issue is happening. With AMD's fglrx driver installed, can you help make sure what graphics mode (I or A) when the issue happens?
To find out which graphics module is in use: aticonfig --pxl To switch to Intel, run the following command and reboot: sudo aticonfig --px-igpu To switch to AMD, run the following command and reboot: sudo aticonfig --px-dgpu Please also include the /var/log/syslog file after failure happens.

(Without the proprietary driver, which means run on the Intel GPU, suspend works fine with it) Steps: 1. Install 14.04 + update (3.13.0-29) + fglrx (2:13.350.1-0ubuntu2) 2. Boot to desktop, suspend it with the option in the power menu 3. Wake it up by pressing the power button Expected result: * Suspend / resume should work. Actual result: * System suspended, but unable to resume properly, it will stuck on the login screen with fan running at full speed. Touchpad and caps Lock LED are not responding Since we will need to test the hybrid graphic feature, and it needs the proprietary driver to switch between the integrated and discrete GPU, I will mark this bug as a blocker.
