Cgminer will not submit on linux.

[Naelr]

Running Ubuntu 11.04 64 bit with CGminer 2.7.5 

when I try to mine litecoins and the pools is either PPS or P2POOL it doesn't matter (bitcoins no problem)... the miner says it is submitting shares and they are accepted but nothing seems to be received by either my PPS pool or my p2pool node.  ON my second box running win 7 I can scrypt mine just fine ... anyone have any ideas ?  thought about upgrading cgminer but on the version before 2.7.5 it wouldn't submit either.

You don't tell us how you are starting the program ie. the command line arguments. It has worked for me since the start of support 2.6.0 or .6.1 I believe for the first version offering it. Running 11.04 64 bit 2.7 sdk 12.6 driver if my memory serves me well.

Yea good point I start it with no command line arguments except calling the config file and here is my config

{
"pools" : [
        {
                "url" : "http://whatever.pool.com:9332",
                "user" : "myaddressyoucan'tsee",
                "pass" : "X"
        }

]

Also the card is a 6950 if that makes any difference

"kernel" : "scrypt",

That option has never worked for me it starts but then tries to mine btc on a ltc pool when I use it I need the --scrypt when starting on the command line then it will actually mine ltc. Here is the file I use when starting it.

Code:

cat ltc.sh 
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100
export DISPLAY=:0
cd ~
cp .cgminer/cgminer.conf-ltc .cgminer/cgminer.conf

~/cgminer-2.8.5 --scrypt --api-listen --api-allow W:127.0.0.1,R:192.168.0.0/24 -g 1 

All other options are in the cgminer.conf. except the core/memory speeds I need to set it manually with another file as if in the .conf file they don't seem to take effect. For your 6950 I find that worksize 256 vectors 4 intensity18 and speeds of 800,1250 get me the best result of nearly 400kh/s on the one I have.

Edit: Here is the cgminer.conf I use as well for the 6950 the threads are 7040 that I use, it is the first card in this conf file.

Code:

cat .cgminer/cgminer.conf
{
"pools" : [
	.......
],

"auto-fan" : true,
"auto-gpu" : true,
"temp-target" : "81",
"gpu-fan" : "0-100",
"intensity" : "18,13",
"vectors" : "4,4",
"worksize" : "256,256",
"thread-concurrency" : "7040,8192",
"log" : "5",
"queue" : "1",
"retry-pause" : "5",
"scan-time" : "60",
"donation" : "0",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}

Thanks for the input .. I will try that as soon as I can on my linux box... will let ya know what happens...

OK made some changes and started with --scrypt flag ... it sends some data to the pool but it isn't mining at the 371 Kh/s it claims it is.. I even updated to cgminer 2.8.5a ... compared to my 6970 in windows... I might as well be cpu mining... the page reports it is getting 3Kh/s after about 3 mins of mining and my 6970 is up to over 86 (the page is average over 15 minutes) ... what will help some logs?

Thanks

That sounds like pool problem to me when I use it they show the correct speed that cgminer shows me. What pool you using? Also my 6970's get 425mh/s using all the same settings as my 6950 except 7200 for the threads. As well there is an official support thread on this forum they can probably help better there by looking at the logs for you I have no clue how to read them.

2 pools.... p2pool and xurious ... on my local p2pool node after running for 30 minutes... the client reports it is going at 315Kh/s and on my node page I only see

Local rate: 8.71kH/s (12% DOA)

when I mine with my 6970 on my windows box to the same pool in just under 10 minutes it is up to 400+ Kh/s rate...

I will check out that that thread tomorrow some time it is late and I am going to bed.
