Zipped because github did not accept the file format

file /sys/bus/wmi/devices/7A4DDFE7-5B5D-40B4-8595-4408E0CC7F56/

It exists

I get this error when I try install it again (first install went without any issues. I uninstalled it then.)

The program did not work with my laptop even when it installed properly. Secure boot is disabled. I rebooted after install, still no luck.Both turbo mode and keyboard did not work.

I am happy to help you with this. If I have to do something (like finding WMI ID) I can help (need some help, because I am not good at these kernel stuff)

Support exists for PH315-53, which worked really well, kudos to it!

Acer default driver in the kernel needs to be loaded.

Try run this command: $ lsmod | grep acer_wmi

The output will be something like this:

➜  ~ lsmod | grep acer_wmi
acer_wmi               28672  0
sparse_keymap          16384  1 acer_wmi
rfkill                 32768  9 acer_wmi,bluetooth,cfg80211
wmi                    36864  3 intel_wmi_thunderbolt,acer_wmi,wmi_bmof
video                  57344  2 acer_wmi,i915
i8042                  32768  1 acer_wmi

If nothing shows up, it is' cause the driver is not being loaded. Maybe driver is listed on blacklist, try it: $ cat /etc/modprobe.d/* | grep acer_wmi

If print something, you need found the file where driver is listed and remove it.

[SuperSecureHuman]

That driver is present Trying again now. I updated kernel recently and have to test it now

[SuperSecureHuman]

Yes, it works now. I have to reinstall the the repo every time I reboot, but I can make it a startup script, and forget about it.

Sadly, the turbo button dosent work in my case. For controlling the fan, I use NBFC and it works like a charm (when ever it dosent work, I have to boot into windows, play with predator sense a bit, change it to default profile, and reboot to linux, and not shutdown. But it happens only sometimes, when I boot into windows, then into linux

Here the shortcut for keyboard brightness is fn + f10. For some reason, when using it for the first time after reboot, it dims the screen to 0%.

[RuiGuilherme]

Ok. Try it:

# ./uninstall.sh
# rm /dev/acer-gkbbl-0
# ./install.sh

[RuiGuilherme]

I made the comment before reading your last comment, can disregard my last comment haha. : D

[SuperSecureHuman]

No issues.

First, I need to see difference in performance for default mode vs turbo mode before I start actually caring about it not being available to me on Linux.

Put some worthy benchmarks to test it.

According to acer, it puts overclock on GPU and CPU. My doubt is, how will u overclock a 11800H? It's a locked variant 🤔

[RuiGuilherme]

Overclock should be done only in the GPU. You can confirm going on Windows and test offical driver.

[JafarAkhondali]

Thanks to https://github.com/JafarAkhondali/acer-predator-turbo-and-rgb-keyboard-linux-module/pull/23, you can now install repo as a service, so you don't have to reinstall it after reboot. I Also think CPU overclocking is doesn't work (OS-independent), but overclocking GPU worked with some benchmarks.
