I am using Ubuntu 18.4 and I own a Radeon R7 270x card. But the Card is not recognized in my system. When I search for the driver on the Radeon Homepage i can only find a Radeon R7 270m .... if i use to install this driver, it will crash my system. There is only divers for R7265 or 270m or R7 300 series.
How can I get the driver for Radeon R7 270x for Ubuntu ?
