hi all hoping for some help. was on my PC on Friday and it went to black screen , so from looking around from what i gather my HDMI cable was not connected to my TV and that was the cause , so need help i have done and tried all of this stuff reboot kill power deleted drivers deleted graphics...

I'm having lots of issues trying to get Ubuntu 16.04 to run on a Lenovo V110-15AST AMD A9 9410 R5 cpu googling seems to throw up a Radeon driver issue, anyone know where I can get this driver.?
