Hi Peter,

Just to provide report that 611 driver works without problem with:
- pymol 0.97
- python 2.3.3
- 2.6.7-gentoo-r12 kernel
- nvidia-kernel-1.0.6111
- nvidia-glx-1.0.6111
- xfree-4.3.0
- GeForce2 Go graphic card (as well as three other types of cards)

Cheers,

Stéphane

Hi, Peter

What Linux are you using? Seems it's not a problem on RedHat linux, I am running both 7.3 and EL-AS, with 2.4.20 and 2.4.21 kernel respectively, and the exact same NVIDIA version without any problem at all. Although we are using python2.2, looks like you are using python2.3, maybe that's the problem?

Best
Chen

Hello.

I did a scan (albeit brief) of the mailing list for this issue, but didn't find
it, so I decided to post it FYI.

I wanted to mention a serious issue I just discovered after installing the new
nvidia drivers for linux (specifically regarding the
"NVIDIA-Linux-x86-1.0-6111-pkg1.run" driver, though I imagine the same is true for all other 6111 drivers), on a 2.4.x kernel, as well as the solution. It may
be important to make a note of this somewhere in the FAQ or installation
instructions (or perhaps it would be easy to fix in one of the pymol scripts).


PROBLEM:
========

Running Pymol gives the following message:

Traceback (most recent call last):
File "/usr/lib/python2.3/site-packages/pymol/__init__.py", line 90, in ?
   import pymol
File "/usr/lib/python2.3/site-packages/pymol/__init__.py", line 306, in ?
   import _cmd
ImportError: libnvidia-tls.so.1: cannot handle TLS data


SOLUTIONS:
==========

There are 2 solutions to this problem.

(1) either rename /usr/lib/tls to something else, or delete it entirely. Pymol then works perfectly ok. However, since this is akin to "If it hurts, cut it off", it might break something down the line. Do note though, that the files
contained within this dir are also in /usr/lib (not a symbolic link).

(2) edit /etc/default/nvidia-glx (if it exists, for me it didn't), and set
USE_TLS to 0. Reboot. Surely there must be another editable config file
somewhere with this option, but I haven't found it.

According to a thread on PyKDE, "The tls (thread local storage) stuff only
works if you are running a tls-enabled glibc on a 2.6 kernel, and when
installing nvidia-glx, you are normally asked by debconf on what to use."

This suggests anyone running the new nvidia drivers on a 2.4.x kernel may encounter this problem. Admittedly, I haven't tested them on a 2.6.x kernel, so
I can't be sure the problem doesn't occur there either.

Hope this helps someone.

Cheers,
Peter
