I am a Mathematica 7 user on amd64 (gentoo-sources 2.6.30-r5) with an nvidia graphics card, and I just completed the same X upgrade this evening. So far Mathematica has not given me any issues. For what it's worth, I also receive the same "compiled for 4.0.2" messages in my logs for the nvidia module, though I have not recompiled my drivers (180.60) since the upgrade. dri and dri2 are not loaded, as you have above. After glancing through your xorg.conf and X logs, I do not see any glaring issues that would cause the problems you are experiencing. Two suggestions (apologies if they have been suggested already): 1) If you haven't already, recompile your xf86* packages. Somehow I missed those when upgrading X, which caused issues for me. 2) Mathematica (at least version 7) ships its own version of Qt, which it will use instead of the system version of Qt. If Mathematica 5 does something similar -- sorry, I have never used that version on Linux, so I do not know -- then it's possible that the old libraries are causing issues. At least in version 7, removing the Mathematica-supplied Qt libraries will cause Mathematica to use the updated system Qt libraries. For me, the Qt libraries shipped with Mathematica are under (install_directory)/SystemFiles/Libraries/Linux-x86-64/. If Mathematica 5 ships libraries that are also installed system-wide, then I would suggest moving the Mathematica files to another location and seeing if using the system libraries helps with your crashing issue. For me, removing the Mathematica Qt libraries made Mathematica faster and look better. Good luck with your issue. Regards, Brandon Vargo
