To reproduce, install the latest Raspberry Pi OS on a pi5, and connect a touch screen display. Then configure the rotation in cmdline.txt and wayfarer.ini. I believe that this is a wayvnc issue. All local USB and bluetooth mouse movements work as expected on the console/screen. Touch screen also registers correctly. It's just the WayVNC session that has reversed X and Y mappings. Before I upgrade the wayvnc service, upon connect it would show the orientation off by 90 degrees before it would do a screen refresh. Once the screen refreshed, it would then show the correct orientation. After wayvnc upgrade to 0.8.0-rc0-2 upon connection it would now show the right screen orientation, however it still had reversed X and Y mouse movements. If I do not rotate the screen, the VNC session works just fine. So something in wayvnc does not know how to map the mouse movements when the display is rotated.

I was hoping to find documentation in wayvnc on the config file to reverse the mouse movements, but did not see anything in the config documentation for that.

To fix this, I switched back to X11 server and vncserver (RealVNC) using the raspi-config tool under advanced options. Then all the mouse movements match up.

It works fine on sway, so I think it's a wayfire bug.

I can confirm this bugger !

@any1 any fix?

I haven't had the time to look into this, and it's not very high on my list of priorities.

@any1 I found some more info about the issue. It seems it's not a way fire bug but an issue with wlroots. There is this issue describing the changes here: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3760 Do you think it contains a fix?

I don't see any references to inverted mouse in that issue.

[steveiliop56]

Yes I know it might have a different name or something. I couldn't understand the changes that's why I asked here.

[steveiliop56]

Is there any temporary fix for that? Can I tweak the config somehow to fix the cursor?

Ahh, it's because wayfire doesn't map the seat to the output: WayfireWM/wayfire#1283

Found this thread after experiencing the same issue with VNC and I don't see a way to solve it. The mouse orientation is incorrect when using VNC - did anyone manage to solve this?
