Difficulty setting up with Ubuntu

[Coinkarlonline]

Hi guys,

I have recently set up an Etheruem Mining rig for last little while now using Radeon 290x card + Radeon 7950 + 1 Nvidia 1070 running Ubuntu, whenever I input command 'ethminer -G -M' I receive the message "No GPU device with sufficient memory was found, Can't GPU mine. Remove the -G argument" . I am currently syncing to Mist and think I might now be using my CPU instead of grafics cards...Any help that can be provided is greatly appreciated!!
