screen backlight not working hp victus 15

fo flag

I have an hp victus 15 gaming laptop (dual gpu) and as soon as I booted up linux the screen went dim. BIOS menu and hp victus symbol remains bright every time I boot it up until the distro icon pops up, then the screen goes dim. Have tried multiple distros (currently using ubuntu 22.10). The buttons and /sys/class/brightness folder both work changing that value, and the only brightness variability i get is when the slider is full it gets slightly dimmer and when it emptys it gets slightly brighter. I've spent a lot of time trying to debug this issue, I have tried many different versions of different drivers, different kernels, different distros, putting things in my /etc/default/grub file, as well as updating my BIOS. I am desperate for some help in troubleshooting and resolving this issue. All help is appreciated.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
