[Lenovo V15-IIL] Screen brightness hotkeys don't work

I had Ubuntu installed on my computer and was using it normally, but I could never control the brightness using the hotkeys. A few days ago, when I tried to start the computer, I received the following error message:

"ACPI BIOS error: could not resolve symbol [\TZ.ETMD], AE_NOT_FOUND
ACPI ERROR: aborting method _SB.IETM._OSC due to previous error
Bluetooth: hci0: Malformed MSFT vendor even: 0x02
irq 9: nobody cared (try booting with the "irqpoll" option)
handlers:[<00000000f27a4891>] acpi_irq
Disabling IRQ #9"

I was unable to access Ubuntu and had to proceed with a reformat. After doing some research, I learned that this may be a problem with the graphics driver, and I am concerned that I may lose access to Ubuntu again and have to constantly reformat my computer.

I would appreciate any assistance in resolving this issue and ensuring that my Ubuntu installation is stable and fully functional. Thank you for your attention to this matter.
