Ubuntu 18 Claymore 12.6 AMD Radeon default drivers

I have installed the new Ubuntu 18 LTS … trying to get Claymore miner to work. When I run Claymore I get the following error:
ZEC: 6 pools are specified
Main ZCash pool is zec-eu1.nanopool.org:6633
AMD OpenCL platform not found
No AMD OPENCLGPUs found, exit

Please help … I’m not sure what else to add here, please let me know

When I look at the driver configuration it looks like this … basically the default drivers that came with the Ubuntu 18 install:
00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)
