One month ago I switched to an Nvidia-based (ASUS GT520, PCI-e) video card on an ~amd64 box. I immediately had problems with the latest Nvidia driver causing a segfault when X started (text console is ok) so I switched to 295.20-r1 and everything was fine.
But I forgot to mask 295.40 and during yesterday's update it got pulled in again, with the same segfault behaviour when starting X. I tried to manually downgrade nvidia-drivers but now glibc is upgraded to 2.15-r1 and nvidia-drivers-295.20-r1 depends on an older glibc (2.14.1-r3, I think). Emerge refuses to downgrade glibc so I am stuck. Since it is a mythtv box I want to stay away from nouveau. No problem myself with it but most of the mythtv development is around proprietary nvidia drivers. What other options do I have? Is everybody running nvidia-drivers-295.40 without problems? thanks, raffaele
