Builds on other Linux machines show black for standard shader

Hi All,
I've made a small demo in Linux editor, it runs fine ( lubuntu 18 ). When I build and run on same machine it runs great. So I copied build onto another machine ( again lubuntu 18 ) and anything that uses standard shader is black. If it's an unlit shader it's fine. So I tried on a friends machine ( lubuntu 16 and 19 ) again black. My development machine has Nvidia, my other and friends have ATI graphics. Is there some issue with ATI builds on unity or is it something else. How can I get over this?
