Just remembered another thing to check in that Properties section of the HFM.exe file.  In the "Permissions" tab, check to see that the "Allow executing file as a program" box has a check-mark in it.  That may have been what did it for me.

Ok so, is there a way to tell what went wrong when Ubuntu crashes? so far ive crashed a time or two and i just dont know what the cause was cause there is no BSOD or anything to get a code from. 
 
also, i can boot and fold in windows at 5.0 Ghz but when i try to boot into Ubuntu, it just give me a black screen with a flickering cursor and then reboots. 
 
any ideas?

so after fiddling with Ubuntu for the last week or so, i think i am fed up with it. It is just not very stable for me at all. 
 
I can fold at 4.9 with no problems in W7 but i cant seem to fold in Ubuntu consistently, even if i drop down to 4.5 Ghz. I get crashes at random points in and nothing is consistent.
 
I have done all of the updates available. 
 
if there is something else i can try to increase stability, let me know, but for now, im moving back to windows. 

for the 6900, i think it was ~24:30 for about 51K ppd. now in linux i would get ~58K ppd at 4.8 but i cant trust it to not crash. it is very random and even down at 4.5 it would still crash. 

~ 1.42 Volts. my chip will do 5ghz at 1.44 vcore and pass 20 passes of linX. But its still finnaky. i cant fold at 5 yet.

So I attempted the gpu folding again using the first gpu guide I mentioned but I still got the same error when running the client. The second guide just looks old so I'm afraid that it will kill my 560Ti driver. I guess I don't know enough about Linux to update the guides for the newest drivers.

Hey rklapp! You helped me, maybe I can help you..start reading this post at post #13:

You may need the OLDER drivers.
 
Don't know if that's the error you are getting, buy it may help anyway.

Thanks. When I initially installed Ubuntu 10.10, I had to load the brand-spanking-new proprietary drivers to get Linux to recognise the 560Ti. When I installed 11.4, the packaged driver automatically recognised the 560. If I go back to an earlier driver, then Linux isn't going to recognise it and the screen will look like low-res crap.

The guides that I've used include modified CUDA drivers that only work with older cards. The irony is that I want to fold on my 2nd gpu (9800gt) because I don't want the primary to take away from the smp folding (no, running at smp-7doesn't help and I don't want to swap the gpus).

 
Hmmm, unfortunately the newer drivers for the latest Fermi cards are giving folders fits right now. They're good for gaming, but not for folding for some reason. Hope you can work it out, man.
As to what I higlighted in red, it won't matter which slot any cards are in, you'll lose CPU cycles no matter how you set it up. I still do a lot of GPU folding with multiple mixed cards on 2 other machines, and using process lasso, it shows quite well the CPU usage for each card. The 470 and 450's use the most, 8-20% depending on wu. The 275's ony use about 2-3% per card. -smp 7 on both of those rigs running -bigadv. At least that's my experience. YMMV
Good luck!

How to monitor the cpu temperature:
Note: I only know how to get it to work in the classic Gnome desktop. In 11.4, you need to select "Classic Desktop" below when you log in to your account. If anyone knows how to do this in the 11.4 Unity desktop, then do tell... do tell...

• Open a Terminal and type $ sudo apt-get install lm-sensors
• Type $ sudo sensors-detect
• This will ask you a bunch of questions that you will reply with Y for each. It will then ask if you want to append the module file and type Y. The sensors that it finds depends on your mobo. For example, my Asus P8P67 Pro has the "adt7574" probe which will only tell me the four core temps.
• Type $ sudo service module-init-tools start
• Type $ sudo sensors
• If you see the sensor readings, then you have done well Padawan. The next step is to show the temps in the Panel (assuming you are using the Classic Desktop).
• Type $ sudo apt-get install lm-sensors sensors-applet

• Right click on one of the top or bottom task bars and select "Hardware Sensors Monitor". This will show the temps for each gpu and each physical core.

I'm on the latest ubuntu and have something available for that, that I'm pretty sure came as part of the default install package.  It's called xsensors 0.70.  I think I got to it by going to the applications folder in the left sidebar,
then click on the "Show [e.g.] 97 more applications", then selecting "xsensors" all the way at the bottom right.  Unfortunately it doesn't tell me which temp corresponds to what, but I have a temp1 reading of 49, and a temp2 of 42, so either those are the two cores of my core i5 or that's a core and a NB temp?  [edit: I have 4 cores...so Temp1 is probably either the temp of Core0 or Tcase?]  If you don't have xsensors you can probably get it with the GUI via the Aptitude Package Manager (which is on my desktop in addition to "terminal" and "update manager", which itself is probably redundant).
 
In any case, once you DO have xsensors (or another such program) installed, after launching it you can dock it to the tray mac-style.  Right click on the icon and select "Keep in Launcher".  Or you can probably make a desktop icon off of the applications folder entry.
 
update to the above..I have since installed lm-sensors as well....this is my output

acpitz-virtual-0
Adapter: Virtual device
temp1:       +42.0°C  (crit = +125.0°C)                  
temp2:       +40.0°C  (crit = +127.0°C)                  
temp3:        +0.0°C  (crit = +127.0°C)                  

coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +45.0°C  (high = +95.0°C, crit = +105.0°C)  

coretemp-isa-0002
Adapter: ISA adapter
Core 2:      +38.0°C  (high = +95.0°C, crit = +105.0°C)  

so xsensor's temp1 is probably the core0 temp and temp2 is probably the core2 temp?  Where the readings for cores 1 and 3 are, I don't know.  also seems odd that an "instantaneous" poll using multiple "drivers" would pull temps up to 3 degrees apart in either direction.

diminishing my contribution a bit: also XSensors can do this without the gnome overlay if you have the lm-sensors package installed and the service started.  You'll see two+ "coretemp" entries in the left panel, which you can click on to see the temp of that core.  but XSensors has a large display footprint and clicking to see what your other core's temp is is kind of a PITA.  So, I like my gnome-panel solution:P

Backing up gnome panel before you begin (source: http://ubuntugenius.wordp...of-your-ubuntu-panel/)
The following commands MAY need to be run with superuser privileges.  in other words sudo gconftool-2...

To backup your Gnome Panel settings, run the following commands in a terminal:
[Edit:pagelm added] mkdir ~/Settings/ [end Edit]
gconftool-2 --dump /apps/panel > ~/Settings/panel_settings

To restore your last saved Gnome Panel settings and refresh the desktop, run:
gconftool-2 --load ~/Settings/panel_settings && killall gnome-panel

 
 
If you did NOT back up your panel before doing the instructions in 77 but want to go back to gnome:
According to http://www.watchingthenet...-default-settings.html you can issue these commands on a commandline (terminal) prompt

gconftool-2 --shutdown
gconftool --recursive-unset /apps/panel
rm -rf ~/.gconf/apps/panel
pkill gnome-panel

You may have to restart your unix session for the default settings to re-propagate.
Note, with a very similar series of commands, some users on another URL have reported not being able to restore the bottom toolbar properly.
Also, I have not personally run this set of commands (I did do all the steps in post 77), so proceed with caution
 
Edit: edited post 77 above to point to this post as well

I try:P

I remember trying to run Xsensors before and got nothing. Now when I installed from the USC and run, it shows the temps as you describe so I'm not sure what I did to make it work. It shows in a window so the sidebar solution is better as you mentioned.
 
I noticed that when I click on the Preferences for the Hardware Sensors Monitor in the taskbar, there is an Alarm option in the Sensors tab that also allows you to run a Command such as sigstop.

if you already have a windows installation, you can use the windows installer and create an easy to remove dual boot.
Or just simply install it on a fresh disk

I run as dual boot, but i don't fold/boinc in linux either, so vmware is a better sol'n there
 
dual boot:
laptop had Win7, I added ubuntu 10 without any sweat
desktop had WinXP, but I managed to fudge over my install when adding debian, so had to reinstall XP again.  Also dual boot

I updated the guide with version 11.10.
