Both Nvidia and Noveau were working fine before my bios update and now they both crash when I change the brightness. Integrated still works fine with brightness and I've tried several Nvidia drivers with no change. Any help would be greatly appreciated, I am not sure where to start.

Alright I figured it out and it brightness adjustments works better now then before my bios update

Here's my fix for my NVIDIA NVS 5400m

sudo nano /etc/default/grub

edited GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

make sure to save and then run sudo update-grub afterwards.

then do this Brightness not working after installing NVIDIA driver
