Try this:

modeline "1280x768" 69.000 1280 1280 1300 1424 768 769 775 812 -hsync -vsync

Sounds to me like its not just a resolution issue. Does it work fine using windows ?

Can youpost a full list of your hardware so i can look into this further ?

drgr33n, first off, thank you for your work.

I have quick question- is it normal for LinuxCoin/Debian Linux to log a user off by simply moving the mouse into the corner of the screen? Specifically, moving to the top-right/bottom-right corners are what causes me to completely log off. I've done this way too many times on accident and had to restart my miners. Is there an option somewhere to disable this?

kjj: Thanks for the response. How do I check for this/fix this issue? Do you recommend I try changing the resolution for example? I'm running it at 1280x768, with no additional modifications to any settings besides disabling the screen-saver.

Yeah, I'd try changing the resolution.  Maybe look for some logs.  I don't use X much, so I'm not sure where to go from here.

I had the same (no X) problem after i installed a second card. I have a 6990 but borrowed a 6870 to try. I read somewhere that the different cards should work although I'd take a performance hit. On windows I got reduced hashrates on crossfire or switching video outs, but on LinuxCoin no X. Card in - X stops. Card out - X works. (regardless of which card I was taking in and out). I tried a fresh non persistent install, no go.

Anyone successfully running LinuxCoin with two 6990s or 6690 and a 6970? (edit)

Wouldn't have worried me except I can't get cron working with DiabloMiner because I can't figure out how to get it to find java, or which bit of java in which folder it needs in path. Groan. Gave the card back unsused as I clearly didn't have the chops to get it going.

drgr33n: any idea of what i might need to add to cron's PATH to get java running from cron?

sjohn: Maybe if you *can* get cron running on cli? Then you wouldn't need remote access or a gui maybe?

Don't run your cards in crossfire and you won't see a performance drop. LinuxCoin was tested using the same setup you have and worked fine ? Maybe something is a miss somewhere else ? If you are having problems I would ask people to list information about their hardware and any other relevant info to the issue. if its problems with X your experiencing can you pastebin the output of


this way I can take a look at exactly whats going on and make sure your hardware is working in the final version of LinuxCoin.


Same applies to you sjohn. If you could post the output of the above code and I will take a look. I've been really busy with work related projects the last week or two so haven't had a lot of time to read through everything. My apologies if I've missed anything !!

Is the Linuxcoin-v0.2a i686 compatible?

I dont have a 64bit CPU.
