AMD Video CARD - Ubuntu 14.04 on the Lenovo ThinkPad Edge S5-S540

Asked by Michele

This laptop has a hybrid video system with two modules:
- Intel® HD 4400 integrated
- AMD Radeon™ HD 8670M with 2 GB of dedicated memory.

With the "xserver-xorg-video-ati" drivers the only module that seems be loaded is the one Intel:

sudo lshw -c video
  *-display
       description: VGA compatible controller
       product: Haswell-ULT Integrated Graphics Controller
       vendor: Intel Corporation
       physical id: 2
       bus info: pci@0000:00:02.0
       version: 0b
       width: 64 bits
       clock: 33MHz
       capabilities: msi pm vga_controller bus_master cap_list rom
       configuration: driver=i915 latency=0
       resources: irq:62 memory:f0000000-f03fffff memory:e0000000-efffffff ioport:5000(size=64)

Instead, if I install the FGLRX driver I can see the two modules and I can choose to use the AMD video card. But the problem is that if I use the AMD video card with the FGLRX driver, the STANDBY function doesn't work correctly (the system freezes after resume) and in general the system is unstable (sometimes it freezes apparently with no reason).
There are any news about this issue?
Thanks in advance.

Hello Michele,
I've linked the bug report here.
You can try the latest driver (version 14.9) from AMD as mentioned in comment #5, it should resolve this suspend issue for you.

Thanks
