WHAT FILE HAS THE MINT DEFAULT RUN LEVEL?

[bluesberryinn]

I need to know how to temporarily change booting from X to run level 3 (CLI), to fix a driver issue.

History: Currently must boot in software rendering mode. Have NVIDIA 610M graphics with Optimus switching to i7 integrated graphics. Driver Manager recommends nvidia-driver-390, but when I install it rebooting gives the Mint black screen of death. Nvidia (http://us.download.nvidia.com/XFree86/L ... rtips.html) suggests this may be due to a problem needing a fix in level 3 BUT Mint booting to level X, hence a black screen (please see Booting to a different runlevel in the link above). Nvidia says that most Linux distros have this is the file /etc/inittab. Fair enough, so I went looking for it. Not to be found. Searched web, no dice. So where does Mint hide the default run level?

Doesn't the grub menu already give you an option for "maintenance mode" or some such language, where you boot into a console w/o X running?

If not....

I make my grub menu by hand, and accomplish the above with:

Code: Select all

menuentry 'LU18 18.04 SDA1  4.15.18-041518-generic SINGLE ' {
  root=(hd0,1)
  linux      /boot/vmlinuz-4.15.18-041518-generic root=/dev/sda1 ro single
  initrd  /boot/initrd.img-4.15.18-041518-generic
}

Namely, just add 'single' to the end of the 'linux' line and it boots to console (pretty sure that's what nvidia wants) rather than a graphical environment with a desktop.

Edit

rebooting gives the Mint black screen of death.

Can you Ctrl+Shift+Fn to a console? (n=1,2,3...try a few)
