Hi Wolfgang,

We haven't tried the new NVIDIA driver yet, so extra thanks for letting us know.

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
