AMD doesn't support Linux Drivers for the Radeon 530 according to some threads I have read.
This seems to be verified in the respect for the latest AMD Driver for the Radeon 530 it only shows drivers for Windows 10. Previous AMD Drivers for the Radeon 530 shows drivers for both Windows 7 and 10 only. No linux drivers.
In one of the threads (https://ubuntu-mate.community/t/amd-radeon-530-drivers/19566 ) it mentioned this updated AMD/NVIDA/Intel linux driver but not sure how reputable it is: Updated Open Graphics Drivers - since 2011! : Oibaf
