Thank you I remembered I had a problem when compiling so I left out the --scrypt option. recompiling did the trick 

BTW what hashrate are you getting with that 7970. your clock speeds seem kinda low. but I'm pretty new to this stuff so I could be wrong. I can't seem to push my card past 700KH/s on scrypt, just wondering if that seems normal.

I am trying to switch from mining BTC to LTC at this point its all for fun. I have run into a problem getting scrypt to work.

I am running a AMD Radeon HD 7900 series at about 700 Mh/s
     I did notice that it drops the difficulty down to 8 before it starts accepting anything

When I try to mine on any pool beside BitCoin I just keep getting restart requests. I noticed my card is still reading out at 700 Mh/s So I assume it is submitting SHA resulting in the restart request from the server. I also noticed all the tutorials start with "cgminer --scrypt" however that results in a unrecognized option. I am running cgminer 3.7.2 on a ubuntu 14.04 system.

I looked at the cgminer man page and it lists the "--scrypt" option so I'm not sure if my build is missing it or if it was taken out of 3.7.2

Any help would be appreciated. Thank you.
