First -- Just read through all posts again and realized that I had gotten the solution for my laptop from the post made by Reticent. So THANK YOU RETICENT for posting that!
Second -- good job fixing boot problem on your own Colin23erk! You're turning into an expert Linux user.
Third -- @ Scott(0) -- I think "quiet splash" is actually correct and doesn't need to be changed. That is how mine is worded.
@Colin23erk,
RE: BACKLIGHT
When you posted output of cat /proc/cmdline on your working OLD LL it was:
That is identical to mine except the two items in blue came after "quiet splash" in mine. So, they're basically the same. Both of the items in blue were additions I made using link from Reticent; so I believe you used same one or one that recommended that also. (The one you had quoted before only said GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor".)
I would recommend you run above command (cat /proc/cmdline) again on both LL installations and compare the results. (Boot into one, run command. Boot into other, run command.) If the NEW install does not have those same items outlined in blue, use this link for instructions to add them; then reboot and see if backlight is fixed.
Regarding "long list of commands that scroll down the black screen before Lite Boots" -- it sounds like it's just not using the splash screen (screen with feather) which normally hides that. If the install boots fine, but only difference is that you can see those lines, then nothing is actually wrong with the installation. I believe the plymouth package is what makes the spash screen work, but not sure how to fix that off top of my head and don't have time to look into it right now. Splash screen is prettier to look at, but all it does is hide that scrolling you are now seeing.
