[chimera-dev] FYI: Chimera crashes X-Server (solved - Nvidia driver problem)

[Wolfgang Lugmayr]

Hi,

Probably you know already, but I found nothing like this in the list 
archive.

Short version:
Use Nvidia driver version 319.49 on Linux when running Chimera.

Long version:
I've setup a new PC with Scientific Linux 6.4 and the latest Nvidia 
driver v319.60. Simple configuration (no stereo).
When running Chimera (official builds 1.8 and 1.8.1) the X-Server 
crashed and logged me out somewhere after the first pop-up window 
(Loading Tix ...).

I recompiled the latest SVN version (1.9_b39272), but still the same effect.
Running the program with --debug-opengl showed no pop-up window on my 
system as on other older Linux PCs.

Debugging the program led to a section in Tkinter/Togl part until the 
server crashes and gives me the login screen.
So I assumed it has more to do with Tk than with Chimera.
I've made a gdb remote debug session with my X-Server (see screenshot).

Based on this info I made a Internet search and more programs have a 
similar problem with newer versions of the Nvidia driver.
All infos recommend the stable 319.49 version.
After this driver installation and a reboot - everything (official and 
my builds) work now fine.

Cheers,
Wolfgang
