OpenSUSE Tumbleweed - Galaxy Book 3 Pro 360

[AP-XD]

Thanks for the sound fix with the necessary verbs, I installed hda-verb and sof-firmware packages and was able to set a cron JOB to execute the verb.sh at every reboot.

Display Backlit was working by default so I didn't set the kernel parameter.

Issues:

• Webcam not DETECTED - Any fix would be appreciated
• Keyboard Backlit is always constant F9 key isn't working - FIX NEEDED
• Left Speaker has little low sound than the right one but can be fixed or adjusted with the balance I found This to be ideal

Hi @AP-XD I don't have the device which you mentioned but regarding some of the issues you highligted:

1. For webcam the GB2Pro (non-360) reports this device (via lsusb):

Bus 003 Device 003: ID 2b7e:c556 SunplusIT Inc 1080p FHD Camera

And according to lsusb -t it is using the module uvcvideo

My guess is whatever the vendor/device ID and/or type for your camera is just not being picked up for some reason?

2. For the keyboard backlight this is also an issue on my device -- assuming it is similar/related but can't be sure of course :) I and others have looked into this a bit but have not found a solution quite yet

3. I agree and have a similar issue -- have considered taking a capture or series of captures with the latest version of QEMU and latest BIOS and see if it helps, but have not gotten to this as of yet! Even better case is if we could figure out exactly what are those few that are really needed and/or work out an actual change/quirk to the device driver so this hack is not even needed at all.

Found this repository before buying the Book3 360 Pro and got it solely for the EMR stylus / display combo so none of the issues are deal-breakers for me, but so far it's been great just taking notes, drawing and following the progress made on the software side. Here's the current status:

• Display / touch / stylus
  Works great
• Camera
  It's a different model, driver is being worked on, see Support for Raptor Lake ( and OV02C10? ) Sensor module not seen by ipu6 modules. intel/ipu6-drivers#171
• Keyboard backlight
  Haven't found a fix. Seems to be unsupported by the kernel.
• Speakers
  Haven't tried the suggested fix due to caveats and the experimental nature of it, but seems to be just a matter of time edit: I've managed to follow the process of reverse-engineering the necessary commands to make the speakers work, documented at [BUG] Samsung Galaxy Book2 Pro 360 no sound through speaker thesofproject/linux#4055 (comment)
• Fingerprint reader
  Thanks to the work over at https://gitlab.freedesktop.org/libfprint/libfprint/-/merge_requests/451 there is now a working (can confirm) driver that seems to be a good merge candidate
• Quiet / Performance mode
  Yet to see modes like these be supported on any laptop I've ever encountered, but could be wrong
• Battery
  Around 6 hours of battery life between 20% and 80%

Much obliged @joshuagrisham

Hi @EverardNisse regarding the speakers issue I saw a lot of buzz in that SOF bug from you so will try to take a look when I can :)

Regarding the Keyboard backlight there is now a very much "alpha" out-of-tree platform driver I have created here: https://github.com/joshuagrisham/samsung-galaxybook-extras which adds a new LED class that lets you control the keyboard backlight. It might be that my keyboard mapping file needs to be updated if you want support for the hotkeys (e.g. fn+f9) but that should be easy enough to sort out (see instructions in that repo about the keyboard mapping filters).

The Quiet/performance mode is also handled by a similar driver+software in Windows so in theory this same platform driver would be able to add support for it. I actually have a lot of traces with examples of all 4 modes but it is a little more complex than the keyboard backlight so will take more debugging, testing, and development to get that part working I think!

The fingerprint reader driver was me also by the way :)

Cheers!

That is wonderful, will try out the fixes when I have the time. Of course I know it's you over at fprint as well 😄 Currently I'm trying to better understand verbs in hope of writing a proper patch.
