I've been REALLY having nothing but troubles with Linux recently. My GPU's aren't defective. They do get hot, but Windows doesn't mind. I even tried setting all my GPU's on stock, but even that doesn't help. They ALL fail. I have 3 GTX260's (216), an 8800GT 256MB, a GT240, & an IGP Geforce 9400.

If I ran Windows, there are few, if any failed WU's. I had troubles with, but also much success with Mint Linux 8 x64 Gnome & KDE. Then I tried Ubuntu 10.04 x64, Gnome, KDE, & Xfce. I get failed WU's almost 100% of the time. I had a lesser, but still very high failure with Mint Linux 9 x64 Gnome. Now I'm close to giving up. maybe I'll try Mint Linux 8 x64 again, maybe not.

I thought that it was due to summer, since my temps are high 70's to high 80's. But Windows doesn't seem to mind & even when I clocked the two OC'ed GTX260's down to stock, they still produced just as much heat & failed just as many WU's.

Any suggestions? Appart from use Windows??? Did Bill Gates buy Ubuntu just to mess it up, or is it GPUGRID that doesn't like to support Linux. No other projects fail in such a way. But then again, I haven't tried going back to Ubuntu 9.10

which version of the nvidia driver are you using? Is your cpu over-clocked?

http://www.gpugrid.net/show_host_detail.php?hostid=70922&http://www.gpugrid.net/show_host_detail.php?hostid=71711 I've just reinstalled with Mint Linux 8 KDE64 using BOINC Client 6.10.56 & NVIDIA Driver 256.25 Before they used Xubuntu 10.04 64bit like http://www.gpugrid.net/show_host_detail.php?hostid=71457&http://www.gpugrid.net/show_host_detail.php?hostid=62706 which all used BOINC Client 6.10.17 & NVIDIA Driver 195.36.15

I still haven't received WU's for the two fresh installs. Only ID: 60998 is OC'ed from 2.4Ghz to 3.0Ghz. That same PC also uses GPU's that are OC'ed. But there is much better cooling & the case also has good airflow. It's the one with the fewest failures. I went back to Mint Linux 8 because I have had it running well with that in the past & I know how to manually change the drivers, which I don't know how to on Ubuntu 10.04

All I can say is that there appears to be a regression in the 256.25 driver that is causing instability on multi gpu set ups.

Its odd that you are completing some and not others.

I'm guessing that you're talking about: http://www.gpugrid.net/show_host_detail.php?hostid=70922 That PC is not only multi GPU, but mixed multi GPU & that the Geforce 9400IGP is Onboard doesn't make it easier. I'm going to give up on the 9400. Even on Windows 7, where it's most stable, it's still too unstable. It's a funny MB. To choose which GPU is used for BOINC, all you have to do is give it more or less RAM then the other GPU. If I want to use the 8800GT I give it less RAM, if I want to use the 9400 I just give it more RAM then the 8800GT, if both, I give it 256MB just like the 8800GT.
