Ok, Thx for the feedback. Here is what I found so far. I will try and boot
with the different kernel parameter if needed but Ill first have to read up
on how to do that correctly.
1) current Kernel marvin- X1-18:~ $ uname -a

2018 x86_64 x86_64 x86_64 GNU/Linux
2) ls /sys/class/ backlight > "ls sys-class- backlight"
