I installed 15.0 'successfully' on an ASUS Z370-G + Intel i7 8700 box. It has an Nvidia Geforce 1050Ti card.

I installed the propriety Nvidia driver NVIDIA-Linux-x86_64-410.93.run after having add blacklisted the nouveau driver in /etc/modprobe.d/50-blacklist.conf by adding to the end of the file -

blacklist nouveau
options nouveau modeset=0
and running 'mkinitrd'

After rebooting with runlevel 3 the Nvidia driver installed ok and my LXDE world is fine at 1920x1080.

However, I noticed 2 things happen -

1. The animated push button screen during boot is gone and is now a screen with 3 horizontal dots. Not fatal but why did this change and can I get the original screen back?
2. And console screen - TTY1, TTY2 etc - is now a very low resolution (80x24??). Where do I check for console resolution to get a higher res?

Bonus question, if the repos update the default kernel later on, do I need to rerun/reinstall the propriety Nvidia driver?
