I have a problem with linux on my laptop, this problem has occurred on every single distro I have tried.

When I turn down my screen brightness with "fn + f5" it goes up and down a bunch for a minute or so. The only time this seems to not be the case is if I turned it too 100% Screen brightness or 0%, It will still say that it is changing and it will say 100% or 0% Brightness and i will hear the sound it makes when you switch brightness.

How do i fix this, so that i can change my screen brightness?

According to proxeIO answer, You can edit /etc/default/grub file:

sudo nano /etc/default/grub

And change the GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" line to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force acpi_osi="

Then run this command, that applies the changes:

sudo update-grub
