@Jamie: Rats. We don't need the plymouth:debug anymore. Would deleting it help? Can you simply go back to where you were last night when you were getting logs (albeit with the tty1 bug). If you can, maybe you can try Seth's new gdm fix.
modeset and nomodeset are other possible things to try (I can't tell from the log what it is doing, and I don't even know if the nvidia driver supports kernel mode setting). In grub the linux cmdline parameters matter, but nothing else should. Grub should be loading the same kernel and initramfs into memory and passing control to linux. The linux command line is the only way to tell the kernel it just loaded to do anything different. The other parameters just tell grub how to behave before it loads the kernel. The xorg.0.log doesn't help. I can't tell if it is the same kind of problem as in this and bug #626723 or not since it just says it's going to give a backtrace and then doesn't. A dmesg or syslog from when the crash occurs may contain more information, you might look there. Attach them if you want us to take a look. Is there an X log in something like :n.log.n that shows the error with more output? It's one thing after another, I'm afraid. -- X starts on wrong tty: pressing enter after 5 minutes crashes X https://bugs.launchpad.net/bugs/625239 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
