For those that went with Debian they've just put the 375.66 drivers into Jessie-backports. All I did to upgrade was:

1. Login as root
2. In a terminal type "service boinc-client stop"
3. Type "apt update" to get the latest list of packages
4. Type "apt upgrade -y" to update it. It pops up a warning about older drivers. Just press enter to continue
5. After its finished (it takes about 5 mins to compile) type "sync" to flush to disk
6. Type "reboot" to reboot the machine

. . LOL

. . I don't think so, because I hadn't encountered this particular problem when I started that thread :)

. . But thanks for the thought.

Stephen

. . But when I tried to install the Nvidia drivers it all went wrong because of something called "Nouveau". It led me through an attempt to remove it and install the drivers but it failed. And I have forgotten how to get the boinc package to install. I tried sudo, sudo apt-get and sudo apt-get install but nothing will install it. What have I forgotten??

. . OK, I gave up chasing my tail with the third party (Nvidia) video drivers since Ubuntu have a repository version of 375 that works, so I went back to my notes and this time it installed without an issue. I really need to rewrite my notes and improve and expand them. I am still at a loss to get BOINC installed.

. . One thing that has cause me to lose even more hair is that when I attempted to copy the download files I have on one of the working Linux rigs onto the new rig via a Flashdrive I ran head on into permission/ownership issues. One of the files I was able to copy was the BOINC install file, but could that be why I cannot install it ??

If the drivers attempt to Blacklist the Open Source driver doesn't work, then simply remove it https://askubuntu.com/questions/412141/uninstall-nouveau
Another method would be to install the repository driver, which also disables nouveau, then drop into the console, remove the repository driver as per previous instructions, and install the nVidia driver as per previous instructions.
The Berkeley BOINC instructions are here, https://setiathome.berkeley.edu/forum_thread.php?id=80636&postid=1836494#1836494
For Security reasons, the Execute bit is disabled when copying files from a USB stick. It's a simple matter to reset it once on your hard drive.

. . Hi and thanks TBar,

. . The issue copying from the Flashdrive wasn't about the execute permission, I set that on all the appropriate files I was able to copy, but ownership issues. Half the files would not copy because Linux said I do not own them :( How frustrating! How are you supposed to transfer files when the host you are moving them to rejects them as not belonging to you the user??

. . Yes, that library was the step I missed in my notes :(

. . As I said I have gone with the Ubuntu 375.39 drivers and that now works, cool-bits is in and working.

. . It turns out that the BOINC install was working, it was just too fast for me to realise that. As soon as I hit the enter key there was an immediate response saying to run the boinc manager run file so I thought I had done something wrong and it had failed, especially as the folder was not where I expected it to be (it is currently under downloads :( ).

. . My problem now is how do I uninstall the current version so I can install that library and re-install it in the right place? Should I use the package manager to do that ??

If I understand you, the BOINC folder is in your Downloads folder. Why don't you simply drag and drop it into the Home folder?

The BOINC working directory can be moved elsewhere as you like, and can even be renamed. One common choice is ~/.boinc, since files and directories with names that begin with "dot" do not show up by default in Unix directory listings. Whatever the name, everything related to the BOINC client is contained within that directory, and you should always run the client and the manager from that working directory.

The Berkeley BOINC folder is entirely portable, if you wish you can copy it to a USB stick and transfer it to another Linux Host, of course you have to reset the Execute bits after moving it via a USB stick. The location of the BOINC folder has absolutely nothing to do with installing the libwxgtk2.8-dev package as those packages are installed in the system folder, Not the BOINC folder.

Just when my xw9400 w/ 4 GTX 960s was starting to level off at around 80K RAC running the Special App, it appears it will have to take some time off.


It first crashed early Wednesday morning, then has only run intermittently since. I figured the PSU was dying, so I first tried switching back to Windows SoG processing, to see if that lessened the load, then disconnected one GPU and then a second. No real help. I also reduced the CPU load, with no improvement. So, tonight I started pulling things apart. Ugghh!

Keeping my fingers crossed that the connector on the MB isn't too fried and that a PSU replacement will do the trick. But not until I figure out what those 2 pins were supplying. That's a job for tomorrow. :^)

. . Hi TBar,

. . I didn't think it would work if I did that, I am too used to the registry getting upset if things are not where they were installed. OK cool, thanks. Not sure why you would want to hide the boinc directory but OK. It's nice to know it is portable.

. . Some Freon and a Qtip should show up how much damage has been done. Did you say you were waiting on a new MoBo? Is there any sign of tracking on the underside of the mobo? (arcing between adjacent printed circuit rails). Anyone willing to bet against it being the 12V lines?

Deja Vu!
Dude, that's exactly how my xw4600 looked after the bout with the ATI 6970. Exact same two pins. In my case, after I picked at it, it only worked as long as there wasn't a card in the #1 slot. The 'new' $22 xw4600 seems to work fine...with a different Power Supply. Seems the two melted pins on the old PS don't work correctly with an ATI 6870, but seems to work in another machine with just an ATI 7750 on an ECS board. The PS I'm using now on the new xw4600 is too small for both ATI cards, and the new PS won't be here 'till Saturday. I think I'll try swapping the cards again after then.

. . Aha!

. . My apologies to Jeff, but I knew somebody had burnt out an ATX connector and was replacing the MoBo. I hope this disease isn't contagious ... :(

Have plenty of QTips, but no Freon. I'll see what I can do tomorrow. I have a replacement PSU ordered (as of a couple hours ago), but will hold off on the MB until I can get a better look at the damage. Amazon has refurbished ones for $19.98, so they're cheap enough, but it's a real PITA to pull the old one out and put a new one in. All those little plugs for the fans, etc., and, oh yeah, a big honkin' water cooler and fresh thermal paste for the CPUs. I'd rather not tackle that project if I don't have to. ;^)

It'll probably be at least a week before a replacement PSU arrives here, so there's probably not much I can do in the meantime. It's a 1050W model, and the box never drew more than about 675W, so I don't think the overall power draw was the issue. However, it's a multi-rail PSU and I suspect I need to figure out just which was overloaded. On my T7400, I had to do a lot of juggling of supplemental connectors to get it to support 3 GPUs. Never before had that problem with either of my xw9400s, but it could be the extra 40-50 watts that the Special App was drawing was just enough to cross the line somewhere. I'll start diagnosing tomorrow.

All those little plugs for the fans, etc., and, oh yeah, a big honkin' water cooler ....

Those are both +12V pins, so if you can move some of the 12V fan draw to SATA/Molex connectors it would help lessen the MB loading. That is they are likely at full speed anyways, so don't really need to be on the MB other than for monitoring.

I'm sure your PSU is fine, just put a new plug on it from an old PSU and maybe patch in 2 replacement ends.

Yeah, the cooler itself has 3 little plugs running off in different directions. Both Molex connectors are currently being used to feed the supplemental connector on one of the GTX 960s, as are a couple of the SATA connectors for another 960. There should still be a couple more SATA power connectors free, but I really need to map out what rails are feeding what before I go trying to shift stuff around.

I'm sure your PSU is fine, just put a new plug on it from an old PSU and maybe patch in 2 replacement ends.

You may very well be right about that, although I assume the existing PSU is the original one and is getting a bit long in the tooth, anyway. And unfortunately, the only old PSU I have laying around is from an old AT rig and the plug just ain't quite what I need. :^)

Anyway, if replacing the PSU will get the box going again, I can track down a new plug somewhere later on and perhaps fix that up. That might give me a 1050W upgrade for the 800W PSU that's currently driving my other xw9400.

Oh well, too much to think about tonight. I'll face it all tomorrow.

Keeping my fingers crossed that the connector on the MB isn't too fried

That connector (motherboard & PSU) is dead, those 2 pins are beyond redemption.

Sure,...have plenty of that stuff around. An old dinosaur has to keep his 8-track players (yes, that's plural) in good working order, after all. ;^)

Was thinking, grab an old molex connector with a female pin, pop it out of the case, and it can be used to insert/twist on the bad MB pin to clean it up.

Hmmm...might try that. I was just playing around with it a few minutes ago and felt like I needed a dental pick or similar tool. All that black in the worst-looking socket is melted gunk from the PSU connector, and no amount of cleaning fluid, or digging with a stiff wire, is going to get it out. The pin in the middle of the socket still looks to be intact, though.

I've ordered a new mobo, just in case. For 20 bucks, I can afford to have a spare handy.
