Please see and provide more details:
Touch screen support on seamless mode is broken (Act as mouse but shouldn't), not sure if it has anything to do with Uinput yet Also touch screen support is broken on ssh X forwarding (Act as mouse), but is not with envioronment variable directly set to remote machine's display
Touch screen support on seamless mode is broken
You have provided no evidence for this. Please see the previous comment and provide more information.
not sure if it has anything to do with Uinput yet
Touch device emulation requires uinput.
Kinda fixed the issue, now it's complaining unmanaged X11 context once i touch the screen
Kinda fixed the issue
So you were not using uinput
and now you are?
now it's complaining unmanaged X11 context
@fan87 Please include the full message.
uinput support is kinda broken (at least in python 3.10). server_util.py line 388

2022-12-26 13:46:19,362 binary mode doesn't take an encoding argument
Fixed it by removing encoding, now what happens is unmanaged X11 context

It spams the stdout so it's performing really slow, I disabled the error output then it doesn't lag anymore, and touch works as mouse.
Did more digging, found out that uinput devices are created, and it's using uinput pointer device instead of xtest pointer device now, but when i click on the screen (touch screen of my linux laptop), its device ID is still -1, which resulted in UInput Pointer Device
Also touch devices are not acting the same touchpad devices, that's why I mentioned not sure if it has anything to do with uinput - because I don't know (and don't think) if touchpad devices is same as touch screen
uinput support is kinda broken (at least in python 3.10)
Thanks! That was recent change in the 5.0 development branch, the commit above fixes that.
Error: unmanaged X11 context
parse_xi_event
The next commit should fix this one and restore parsing of XI2 events.

I can't remember all the details, but that looks correct.
because I don't know (and don't think) if touchpad devices is same as touch screen
IIRC they're close enough, and it's not easy to differentiate.
Not sure how useful that's going to be, but there are APIs we can use for simulating touch events in shadow mode: https://github.com/Xpra-org/xpra/issues/3750#issuecomment-1420793669 libei claims to have support for touch devices, but I'm not sure yet if this is going to work with X11 (how would it?).

Is your feature request related to a problem? Please describe. Touch screens are currently unsupported and they will be emulated as mouse input, scrolling and other touch actions won't work. (Not HTML Client, X11)
Describe the solution you'd like Emulate a touch screen (Not a touchpad)
I've seen there's an open issue for Touch Device, but apparently it's not touch screen but touch pad / drawing tablet.
