Further news... I managed to boot find by installing older kernel 2.6.31-21-generic (from ftp://ftp.ubuntu.com/ubuntu/pool/main/l/linux/), still with the nvidia-current (195.36.15) package.
So far, it seems to work all right - I had a graphic message telling me that nvidia-current had failed to install, but glxinfo teels me I am using the proprietary driver, so it seems OK. So there's definitely a specific problem with 195.36.15 that appears with kernels 2.6.32 and above, when multiple GPU are installed... -- Cannot install nvidia 195.36.15 - crashes system https://bugs.launchpad.net/bugs/548362 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
