Just goto amd website. In the navigation, go to drivers, goto linux
drivers download the 121 mb zip file unzip and follow the instructions.

Title:
[Samsung NP535U3C-A03DE] Blank screen on resume from suspend
Status in “linux” package in Ubuntu:
Fix Committed
Bug description:
when resuming from suspend, the screen remains blank, while the system
ist still operational (logging in using ssh works).
* restarting X doesn't help ("sudo restart lightdm" through ssh)
* disabling KMS (nomodeset) doesn't help, still blank screen after pm-suspend
* updating to xorg-edgers kernel 3.7.0-7 doesn't help
* mainline kernel from
http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/ (3.8.0.999) didn't
work either
* playing around with acpi_os_name had no effect
I tried following the debugging instructions from
https://wiki.ubuntu.com/DebuggingKernelSuspend, but I have no
/sys/power/pm_trace (even on mainline kernel)
The system is a brand new Samsung 535U3C-A03 with an AMD A4-4355M
(integrated Radeon HD 7400G).
