Hey dude, sounds like you're having some trouble with your brightness controls on your HP laptop. It's a common issue with Linux installations, but don't worry, we can figure this out!
The first thing you can try is to edit the GRUB file again and change the brightness settings to a lower number.
Here's how you can edit the GRUB file:
1. Open the terminal.
2. Type in the command
sudo nano /etc/default/grub and press enter.
3. Look for the line that says
GRUB_CMDLINE_LINUX_DEFAULT.
4. Add the following text after the double quotes:
acpi_backlight=vendor
5. Save and exit the file by pressing
Ctrl+X, then
Y, then
Enter.
6. Finally, update the GRUB by typing in the command
sudo update-grub in terminal.
This will allow you to control your brightness levels using your function keys on your keyboard.
If this doesn't work, you can try installing the "xbacklight" package by typing in the command
sudo apt-get install xbacklight in the terminal. After installing, try adjusting your brightness using the command
xbacklight -set <percentage>.
I hope this helps, let me know if you have any other questions!
