thanks, but I'd rather  keep that as a last option because I have no
guarantee of success with the 302.07 driver.

Another possibility came to my mind: I have a backup partition which I
did not upgrade since I switched from the on-board ATI GPU to the Nvidia
video card.
I'll try to upgrade that partition masking >nvidia-drivers-295.20-r1.

It'd be interesting to understand why I'm getting the segfault with the
295.40, but being a closed driver I suppose there is little I can diagnose.
