I use dual boot on my lenovo ideapad 320. Windows 10 and ubuntu 19.04 at the same time. In order to get ubuntu working I have to disable Radeon 530 from UEFI using "only use UMA" setting. This causes problems such as low performance on ubuntu and whenever I try to fix UEFI for windows and reboot, windows drivers also get deleted or corrupted. In order to stop this madness I need official Radeon 530 drivers for linux. Please help me.
