The bug is still there in Ubuntu 11.10 Oneiric Ocelot. I installed the new release a few days ago and experienced the same problems with the nVidia chipset/driver. The suggested solution ( http://www.warp1337.com/content/ubuntu-1104-natty-segmentation-fault- nvidia-geforce-9-series-kernel-failure-solved) does not solve this issue. 2011/7/21 Rasmus Nielsen
