RGB seems to be working but the default turbo button (pressing red button 1) does nothing.

sudo dmidecode | grep "Product Name" -B 2 -A 4

sudo cat /sys/firmware/acpi/tables/DSDT > dsdt.aml - doesn't return anything.

I tried manually going into the DSDT folder but it won't allow me to do so. Any ideas on what to try next?

Hi Above command puts DSDT data in a file called dsdt.aml in your current working directory. Please press your red button several times, then report the output of this command:
sudo dmesg | tail | grep "Unknown function number"

Also I haven't check codes for your laptop, so it will be just a trial\error process to enable turbo mode

Change this line: https://github.com/JafarAkhondali/acer-predator-turbo-and-rgb-keyboard-linux-module/blob/c0f99438d7f684d12b03ff811705ca80f7ecf51a/src/facer.c#L2549

to: if (return_value.key_num == 0x2)

and add this:

{
				.callback = dmi_matched,
				.ident = "Acer Predator G9-793",
				.matches = {
						DMI_MATCH(DMI_SYS_VENDOR, "Acer"),
						DMI_MATCH(DMI_PRODUCT_NAME, "Predator G9-793"),
				},
				.driver_data = &quirk_acer_predator_pt917_71,
		},

after line 770 in facer.c.

Do a reboot, then try installing.

I have no idea if it would work, I just used similar code for your laptop. Use at your own risk.

I'll give it a shot when I get back in town. Cheers!
