Samsung TabPro S Linux compatibility tweaks

This is a collection of scripts, quirks and patches to improve the use of a Samsung TabPro S under Linux distros.

A couple of items require some attention for this device

  • The NIC is an ath10k QCA6174. The firmware support for this device is rather messy and the wrong set of files will break it. Place the contents of the ath10k/QCA6174/hw3.0 dir in /lib/firmware and be sure to delete anything else in there. This firmware works very well (30MByte/s on 5ghz without issue) on 4.7.x.
  • Brightness changes do not work with intel_backlight, probably because the display is OLED. The way to adjust brightness is by means of xrandr --brightness; a script is included that uses inotify to monitor changes to intel_backlight so that all existing brightness management tools can function correctly. It should be started with your display manager or in your user session.
  • TODO: Audio does not work yet. This is an ongoing investigation, but it appears that the ALC298 codec is getting misconfigured because headphone works at double speed/pitch, but speakers produce no sound whatsoever under 4.7/4.8/4.9 kernels. Bugzilla report is https://bugzilla.kernel.org/show_bug.cgi?id=188411
  • TODO: There is an SMO8A80 accelerometer which is visible through i2s; it should be leveraged to enable auto rotation
  • TODO: When disconnecting and reconnecting the dock, the touchpad on the dock stops working. Cause as of yet unknown, but likely an X or synaptics issue.
  • TODO: Buttons not tested yet, may or may not work.

samsung_tabpro_s's Issues

Audio support

Thanks to set up this repository.
In case you are still using this machine, are there any piece of news about the audio support?
Did you find out a way to fix it in the meanwhile?
(unfortunately it seems there haven't been any changes related to this bug https://bugzilla.kernel.org/show_bug.cgi?id=188411)
Many thanks again

Touchpad

It's a relief to finally see others having the same problems with the Tab Pro S.
Any updates on the touchpad problem?
The touchpad not working properly is my biggest concern at the moment, if I can't fix it I might return to Windows.

Battery

Hello!

Dont know if this is the proper place for my question but I'll go ahaid anyway. I was just wondering how the battery life is working out for you when using linux..

Thnx

Gamma

Calling xrandr --output eDP1 --brightness 0.5 also seems to reset the gamma to 1.0:1.0:1.0, which interferes with applications like redshift.

Something like this might work, except in the case there are multiple monitors and with different gamma values:

gamma_val=$(xrandr --verbose | grep "Gamma:" | grep --only-matching "[0-9]\.[0-9]:[0-9]\.[0-9]:[0-9]\.[0-9]")
xrandr --output eDP1 --brightness "${luminance}" --gamma "${gamma_val}"

Thoughts?

btw just set up this tabpro with manjaro kde and using this repo, very happy with it! Thanks for putting this out there.

WSL

I picked up a TabPro S at the beginning of 2020 thinking I would run linux on it. It wound up being too frustrating.
I also love the screen so much that I can't bring myself to sell it. So, I wound up with a great big hack:

Loaded Win10 and all the Samsung proprietary drivers. Then I spent a day turning off all the adware built into windows.
Then, and to my surprise, I was able to upgrade to Win11 (have to be part of their insider program to do this)
So, yes, I have secure boot enabled. I'm also pleased that the Samsung drivers provided an option to charge the battery only to 85% - claiming that this will extend its life. I have not seen that trick before.

I installed and run Ubuntu on Windows Subsystem for Linux. Most things work - even GUI apps. (virt-manager for example)
The disk access is slow, but I'm not really doing disk intensive things from this PC anyway.

I still need to see about getting snaps to work, but there is evidence that can be done.

I think everything I've done is really straight-forward. I just wanted to leave some bread crumbs about this option.

Wireless driver does not work on kernel 4.18

I installed the wireless driver as in the readme by deleting the contents of firmware and copying in the two files from ath10k/QCA6174/hw3.0. I rebooted the tablet and there are still no visible wireless networks. I rebooted again with the same result. Tested on a fresh install of Kubuntu 18.10 with kernel 4.18.
