I noted that when boot hangs (during plymouth, but before kwin starts) the xorg.log always shows:
open acpi socket failed then continues to load stuff ( amongst others glx nividea module) then start loading dri2 and then complains it can not load the nividea driver. I have not found a solution, but this work around seems to work: press F8 during plymouth and kwin starts. Now xorg shows acpi socket openede succesfully Ferry -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/769846 Title: Can't Boot into natty after installing nvidia driver -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
