I have recently installed Ubuntu for the first time and it is running exceptionally slow.
Version:
No LSB modules are available.

My graphics controller:
VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Carrizo [1002:9874] (rev c5) (prog-if 00 [VGA controller])
For which I have installed graphics drivers using sudo apt-get install amd64-microcore. My laptop specs do not warrant the slow behaviour, which is AMD Quad-Core A10-8700P APU with Radeon™ R6 Graphics (1.8 GHz, up to 3.2 GHz, 2 MB cache) and 12 GB RAM.
Does anyone have any idea why it may be running so slowly?
Edit:
Using lspci -nnk | grep -A4 VGA returns the following:
VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Carrizo [1002:9874] (rev c5)
DeviceName: ATI EG BROADWAY
