View Full Version : Linux client needs a video card ?

If you dont have a video card installed the client doesn't start.
It just sits there doing nothing after
Server msg: RSA576 will be afraid...

It ran fine on the first node I tried because I was using a monitor and keyboard
on it.

None of the others will start unless I fit a videocard and plug the monitor in.
Without a monitor attached the video card doesn't initialise and the client wont start.

I find it hard to believe a nix program won't run without a videocard.

hrmmm... interesting. Have you tryed running it via nohup?

nohup ./client &

(could possibly also try piping to /dev/null)

That would pipe all output to a file called nohup.out. I don't know if it would work, but I would assume that if the output is being piped elsewhere (other than the video card) it may possibly run. I have it running like that on two machines fine. But they have video cards, so I don't know if it would work for you guys with diskless nodes. If it does work then you could just 'tail' the file to keep track of progress.

BTW I the Celeron 333 box has a video card, but no monitor connected and it works fine. I just SSH to it to start the client with nohup and I have had no problems with it. The nohup.out file shows that it's working just fine.

I tried using nohup and piping to dev/null but no joy there.

I got a response to a post I made on the official forum so perhaps I will be able to use the PXE farm soon.

Wow, at least he took the time to build a client without display just for you and rsbriggs :D He could have easily just said "tough luck"

Well PCZ I decided to do some testing this morning with no video card. Turns out their client isn't the only program that hangs without a monitor. GRUB bootloader will hang as well without a video card, due to the BIOS VGA calls when calling the printf or MSG(x) functions.

I'll give the new version a try when I get home this evening. (Did it work for you PCZ?) Much as I like the AMD 2400+ diskless nodes for some things, they are just way too slow trying to run GIMPS....

Hmmm. Seems like someone must have "optimized" ANSI graphics to go direct to the video card or something, rather than through the termio drivers...

Yeah seems they didn't plan ahead in this area :p The new client isn't ready yet, the first two he released didn't work for PCZ, he's working on it now. I informed him what the problem is, he said he'll release future linux clients with a --no-vga option in the future :cheers:

I think he wants that new server:D

:tempted:

They are very fast at RSA and EON.

In the words of Fobot "use the right tool for the job"

I couldn't get EON to run on them either. It might just be that the server was down at the time.... Will probably do some re-arranging of things over the weekend.

I'll leave GIMPS to the P4's and run some EON and RSA on the AMDs.

Unfortunatly the AMDs aren't very proficient for GIMPS :(

I'm starting to wonder if he gave up on doing it already. I e-mailed him just about 24 hours ago and no response, he doesn't seem too interested in the thread either :rolleyes: I'll see if I can talk some sense into him...
