[pccs]

All shares being rejected for some reason.

Do I have something configured wrong?

Youre not running scrypt.

Youre not running scrypt.

Changed it and tried it with scrypt, got the same result.

I'm on bitcoins now and it's workin fine. HD6450 ~ 30Mh/s at I=9

If you're on Linux with cgminer, for Litecoin, you need to run (or add to your script):

export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100

This works around some various bugs/creativities in the AMD drivers that trip up cgminer.
