FAHViewer v7.3.6 doesn't launch under Ubuntu

[batisteo]

Under Ubuntu 12.04 (precise) 32 bits Cinnamon, FAHViewer doesn't launch. The window seems to be created, and immediatly closes.
Free driver nouveau for NVidia seems to be used.

What could I do to fix this, or help to fix this?

Hardware: Asus A6Jc (NVidia™ GeForce™ Go7300 128MB)

Welcome to foldingforum.org, batisteo.

FAHViewer requires OpenGL. It may or may not be included with the drivers. I don't remember the minimum version.

[batisteo]

Hi Bruce!
Thanks for the fast answer!

Here are the Viewer requirements: the Operating System should support OpenGL version 2.0 or higher.
fah-web.stanford.edu/projects/FAHClient/wiki/FahViewer#Requirements

After installing the following packages, the error message remains the same:

• freeglut3
• libgl1-mesa-dri-experimental

glxinfo gives me:
GLX version: 1.4
OpenGL version string: 2.1 Mesa 8.0.4

I think it's fair to assume that 'nvfx' is the NVidia graphics code that's reporting the error. Let's assume that it has something to do with the Open-Source nouveau driver. Have you searched the nouveau support site for similar messages?

It's worth trying other video drivers. There have been a number of reports that the proprietary NVidia drivers work better in many situations. Let us know if that fixes the problem. (I have no idea what support for the Go 7300 you'll find. I do know it's too old to be supported for actual GPU folding, but that doesn't mean the Viewer won't work.)

It should also be noted that the FAHViewer is very nice to have, Folding calculations do not depend on it.

Sadly, my understanding is that you need the 64 bit version to fold and not the 32 bit

the link will explain all.
Credit to musky of the [H]ord for the work, he says " The Linux FAH client is 64 bit, meaning the OS needs to be a 64 bit version as well. You cannot fold with a 32 bit Linux install."
I can only copy and paste

http://hardforum.com/showthread.php?t=1601608

I am running 64 bit and the Latest V7 it folds very well and I can add/delete/change the settings/configuration from a stock install.
I have never used the FAH viewer in over 4 years of folding so I can't help there

While that may have been true at one time, there is some contrary evidence http://foldingforum.org/viewtopic.php?f=88&t=24037

It is possible that the viewer needs 64-bit. My Linux is 64-bit, so I can't offer first-hand information.

A limited selection of SMP projects can run on 32-bit Linux. Other projects are only available on 64-bit Linux.

OK, Thanks,
