Do you know if your tablet has a "native" orientation of portrait? I wonder if the coordinates are now normalized to the natural orientation of the display.

When it boots does the logo show up in the portrait or landscape orientation?

[Chacal1988]

The native orientation of my tablet is Landscape.
The "Lenovo" logo starts in landscape mode when i turn it on.
I just try disabling "screen rotaion" and "smart rotation", reestarted the device and the result is the same, mouse axis still rotated...

[Chacal1988]

Maybe adding an option to rotate the Axis in the configuration menu sounds like a good idea!

I looked through the Android AOSP source code to see if I could figure out what changed in Android 13 and it looks like there was a bug that shipped in the original Android 13 release that caused this issue. The bug was resolved by this commit: https://cs.android.com/android/_/android/platform/frameworks/native/+/258e2b909a91e893bf8cdd5b46ac7a9446de2549

I looked through the various Android 13 branches in AOSP and confirmed that fix was not present in the original Android 13 release (TP1A), but it was present starting in the December update for Pixel devices (TQ1A). Depending on when manufacturers branched from the AOSP code for Android 13 and if they merged in fixes from upstream AOSP code, some Android 13 devices may or may not be affected.

I will test and see if this behavior can somehow be detected and corrected automatically, but it may not be possible if there's no other reference available in the input events to determine how to undo the incorrect rotation performed by Android.

Cgutman, you are a god level human, and i hope your friends and family love you as much as you deserve.
Thank you for your time!

[Chacal1988]

I just discover that if i split the screen in half, and use Moonlight in one side and at the same time another app in the other half of the screen, then the mouse moves just fine.
It is useless because the screen is so small, but at least i hope that helps you in some way finding a solution.
Thank you again!

Unfortunately, it does not seem possible to detect the swapped axis values reliably. Unlike SOURCE_TRACKPAD which does provide X and Y values in both relative deltas and absolute position, SOURCE_MOUSE_RELATIVE does not. It populates the same relative deltas in both AXIS_X/Y and AXIS_RELATIVE_X/Y, therefore it's not possible to determine if the relative deltas are rotated (and more importantly, which direction they are rotated).

There is probably no real solution other than asking your device manufacturer to incorporate the patch I linked or wait until Android 14 is released for your device. I have a build of Moonlight that just swaps the X and Y axes for all SOURCE_MOUSE_RELATIVE devices all the time, but it's definitely not something that I can include in an official release (since it will break all devices without this bug). Here is the build you can try: https://drive.google.com/file/d/19YHru1ZXMH6f1WSigsmypsPwunRkc4BH/view?usp=sharing

@cgutman Thank u very much for your time, but im sorry to say that the X axis is inverted...
When i move the mouse left the cursor moves right, and when i move right the cursor moves left.
Y Axis is working perfect now! Up and down works just fine!

[cgutman]

Ok, this build inverts the X axis too - https://drive.google.com/file/d/1956ffbPYfCEOexGUmsHQg2WYKVBCl8eK/view?usp=sharing

[Chacal1988]

It works perfect!!! You are, from now on, a god like human to me.
Dont u think Moonlight team should add an option in the config menu to change mouse axis movement?
Android 13 will live forever on some tablets and phones...
Thanks again! Your help was beyond my expectations.

+1 to add the optional "Invert X" and "Invert Y" setting.

Thanks so much @cgutman for finding the root cause and providing the modified builds!

好的，这个构建也反转了 X 轴 - https://drive.google.com/file/d/1956ffbPYfCEOexGUmsHQg2WYKVBCl8eK/view?usp=sharing

Can you send a latest version, I also encountered this problem, the same Lenovo Android tablet, the model is Pad Pro 12.7, thank you very much

[Jim29er]

+1 for the option of inverting the mouse axes in the Moonlight settings!

Knowing Lenovo we cant expect any support from their absolute bots aka customer support. Anyone know a workaround for this ?

I recall I got it fixed temporarily by running my games etc in borderless mode via parsec but the problem still persists on Android games and any fullscreen app.

I regret buying this shit tab every day
