Re: TTY1 doesn't run at boot, but TTYs 2-6 are OK
Waht version os Lubuntu are you using ?
If it is 12.04 or greater then it is using LightDM as the desktop manager.
You can ensure LightDm does not start at startup by creating an override file and this is the way you want to be doing it.
Remove that text parameter from grub as that was only ever a hack to ensure GDM did not boot at startup and, if i remember correctly, was part of GDM's startup scripts.
So, put the system back as it was.
After that, boot into your system and from a terminal or console type
Thst should do it for you.
echo "manual" | sudo tee /etc/init/lightdm.override
