It's 4:30am, going to sleep...
Way too high core clock. Start with 1050 and you can move up a bit maybe around 1140.
Memclock to 1500
This generally works good for most 7970 -I 13 -g 2 -w 256 --thread-concurrency 8192.
Very rarely you can't use 2 threads (search for The Stilt's bioses), in that case -I 20 -g 1 -w 256 --thread-concurrency 24000 and tweak TC to higher numbers upto stability.
Also add to the startup script for sgminer
#!/bin/bash
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1
config now set as follows, still no effect on speed:
./sgminer -k darkcoin \
-o stratum+tcp://lotterymining.com:4444 -u un -p pw \
--thread-concurrency 8192 -I 13 -g 2 -w 256 \
--gpu-engine 1050 --gpu-memclock 1500
It still complains about the exported variables as if they hadn't been exported.

I have a hunch that ADL/OpenCL whining is part of the problem. I think the values passed in the command line are being ignored. Thus, why setting GPU clock to 1500 didn't do anything bad or good; it's not actually happening.
Also, found that libGL.so is only being installed in /usr/lib32/ which is complete fail. No idea what it previously was just fine but then went poof. Tried manually linking /usr/lib/libGL.so to /usr/lib32/fglrx/libGL.so.1.2 and that is a disaster, as expected... It's just plain borked up beyond hope and I'm done wasting my time on it. I have too much real work to do to play these games with busted ubuntu crap.
