I'm using Ubuntu 14.04 64-bit (out of the box, updated) and I'm having
the same issue. My hardware is a laptop Asus with AMD A8-4500M Trinity
APU (Radeon HD 7640G) and updated BIOS. To make some Fn keys work I had
to add "acpi_osi='!Windows 2012' to my grub command line, I'm dual
booting Windows 7.
@Casey Maybe you can dive into your /var/log directory. If you are that
novice you can make use of a graphical log viewer that you can install
from the ubuntu software centre. One or two logs where you can start is
/var/log/messages or /var/log/Xorg.xxx or even /var/log/boot to see if
there was so
@Casey Sorry for double posting but I forgot one important log and can't
find an "edit" button or option. Chechk your /var/log/pm-suspend.log too

It is a very odd behavior with this AMD A8 4500M processor. I'm having
the same issue in post-precise installations. Open drivers are better,
but we can't use them because we can't use the display after suspend.

Maybe they are actually several bugs. And I don't know if this is
important but when I wake my laptop from suspend:
1) No matter if I have xscreensaver installed or not, the screen keeps as if it
was off and everything else seems to be working.
2) I can "wake" my laptop with ANY KEY.

I just found a working solution for Xubuntu 14.04 updated, uninstalled
Gnumeric and Abiword and installed Libreoffice and htop (but I don't
think this matters, just want to be clear it is not a completely fresh
install). My laptop is an ASUS K55N with AMD A8-4500M Trinity APU and

Here again.
My workaround works but only because Xfce does not rely on 3D
acceleration. If you try to change to a compositor that relies on OpenGL
you'll get into trouble. Thats why my CPU temperature got higher. So, if
you want to use a pretty and modern desktop like KDE, GNOME, Cinnamon,

nomodeset as a kernel parameter fix the problem. But, if you use
nomodeset then you'll get software 3D acceleration in a clean
installation (it seems radeon driver breaks suspend). If you install
fglrx (binary blob) then you MUST use nomodeset to disable radeon (open
source) driver to load. Then, y
@Patrick So, if you boot with nomodeset kernel parameter you can't wake
from suspend? I tried yesterday Sabayon Linux 14.05. They use the binary
blob as default when possible, if they can't use binary blob they
fallback to X.org radeon driver. The same behavior should be for nouveau
and binary nVID
