I'm having trouble stopping X over SSH, on an Ubuntu 11.10 system. I'm nowhere near the computer so the usual Control-Alt-F1 is out, although I'm not sure if this actually stops X in 11.10. I'm trying to install the 285.05.33 Nvidia developer driver.
ERROR: An NVIDIA kernel module 'nvidia' appears to already be loaded in your kernel. This may be because it is in use (for example, by the X server), but may also happen if your kernel was configured without support for module unloading. Please be sure you have exited X before attempting to upgrade your driver. If you have exited X, know that your kernel supports module unloading, and still receive this message, then an error may have occured that has corrupted the NVIDIA kernel module's usage count; the simplest remedy is to reboot your computer.
Installation log file - http://db.tt/YNyYF0wR
and in /etc/modprobe.d/blacklist.conf,
blacklist vga16fb blacklist nouveau blacklist rivafb blacklist nvidiafb blacklist rivatv blacklist nvidia
sudo stop lightdm
does not recognize a job to stop, when the 'text' flag is in the grub configuration file. Also I am not porting X over SSH.
Thanks for any ideas
