on HD7950 instal driver 12.6
with cgminer 2.6 on windows 7 x64 BTC hashe rate is : ~535MHs
whit cgminer 2.6 on XUBUBTU 12.4 x64 BTC hashe rate is : ~499MHs
windows beat up linux in my case whit 40MHs on BTC digging
with cgminer 2.6 on windows 7 x64 LTC hashe rate is : ~250kHs
whit cgminer 2.6 on XUBUBTU 12.4 x64 LTC hashe rate is : ~300kHs
with 12.6 is a little better,
but is not so good compare 6950 on LTC do ~405kH/s

no so big difference for LTC
edit:
considering that result i think windows is better decision in my case

this is with 12.4 driver

Did you run

What are you stock clock rates? Maybe try experimenting there a little with engine and memory clocks upwards and downwards, the hash rates can vary quite a bit depending on the ratio of engine to memory
export GPU_MAX_ALLOC_PERCENT=100

Use cgminer and these settings
--scrypt -I 19 --shaders 1792 --thread-concurrency 8960 -g 1
Should get 500+ kh/s
also try --thread-concurrency of 17920, may be a little faster
for the 7xxx series you must always use -g 1 to achieve high intensities
a lot of reject A:6 R:85 ~600kH/s
i try a low intensity 15 result : A:30 R:73 ~370kH/s
still no good result

you have not readed either, some cards can not go over -I 13 !
ckolivas,
now i run xubuntu 12.4
cgminer 2.6 with this settings :
--scrypt -I 14 --shaders 1792 -g 1
it run normal , if i increase intensity start rejecting,
but a hash rate i think is little be low >260kH/s
now i run xubuntu 12.4

come one mining linux guru how to increase hashe rate ?

Ah fuck a problem of scale. Hashrate will look too low making it think it's sick for scrypt only. I'll fix it tomorrow.
Thank you sir for looking into this issue and your effort to date!
The latest cgminer 2.6.0 reports the gpus SICK after about a minute or two of mining but appears to hash away just fine and submit shares successfully this is on windows 7 and Ubuntu-12.04

If any of you run 6950, those settings seem to work fine:
I have not fraked with any aticonfig setting.
If you find better options, please post them here.
Cheers and happy LTC mining
Code:
./cgminer --scrypt -o http://xxxxx:9332 -u USER -p PASS --worksize 256 --lookup-gap 2 --thread-concurrency 7040 -g 1 --intensity 19
I get (avg):403.4 Kh/s I have not fraked with any aticonfig setting.
If you find better options, please post them here.
Cheers and happy LTC mining
i try to run HD7950 , but only a half of HD6950 hashe rate , or cgminer crash , look past 2.3 pages

great new release cgminer 2.6 , but the same problems 
...
now I'm starting to think about does it make sense to buy one more HD7950 eventually, unable to work only one to digging LTC.
will take more RAM for the system tomorrow to see if it has an effect.
meanwhile I saw manual somewhere for ubuntu and cgminer, but I can not find it now

Deserving of a bump to get this above the drama-rama!
