Wayland does not currently have a known method to lock touching to a specific display in any environment other than sway (or wlroots-based supported compositors). Xinput -map-to-output "Wacom HID 4861 Finger touch" "eDP1"Īnd start, test and enable the systemd/User service rvice. Install xrandr-watch-git AUR, create a script ~/.xrandr-changed with execution permission to perform map-to-output, for example: There are xrandr events we can capture from a script.

Using xrandr-watch-git to automate map-to-output The Calibrating Touchscreen page has an example udev rule for the case when a transformation matrix has been calculated manually and needs to be applied automatically. In that case it is better to use a udev rule.

The mapping will be lost if the touchscreen is disconnected and re-connected, for example, when switching monitors via a KVM. You can automate this by putting these commands in your ~/.xinitrc or similar. $ xinput -map-to-output 'Serial Wacom Tablet WACf004 eraser' LVDS1 $ xinput -map-to-output 'Serial Wacom Tablet WACf004 stylus' LVDS1 We now need to simply map our inputs to our output like so: ⎜ ↳ Serial Wacom Tablet WACf004 eraser id=14 ⎜ ↳ Serial Wacom Tablet WACf004 stylus id=13 $ xinput -list ⎡ Virtual core pointer id=2 So we have to find the ID of the stylus input: We wish to map our stylus input to LVDS1. LVDS1 is the display internal to the tablet, and VGA1 is the external monitor. VGA1 connected 1920x1080+1024+0 (normal left inverted right x axis y axis) 477mm x 268mm LVDS1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm Take for example the setup of having a wacom tablet and an external monitor xrandr shows both displays: This can be achieved with xinput as follows. To use multiple displays (some of which are touchscreens), you need to tell Xorg the mapping between the touch surface and the screen. Using a touchscreen in a multi-head setup Then, run xinput_calibrator and follow the instructions. There is a hack to emulates this scrolling behavior for every application in #Touchegg, but the X server still handles it as text selection (at least with Plasma). The two-fingers scrolling has to be implemented on the application side (see this link).įor Firefox, see Firefox/Tweaks#Enable touchscreen gestures. Again, evdev is likely to be the default if your touchscreen "just works." Proprietary drivers exist for some devices (e.g.: xf86-input-egalax AUR), but it is recommended to try the open source drivers first.ĭepending on your touchscreen device choose an appropriate driver. Less common drivers, not contained in the repository, are: xf86-input-evdev (likely the default driver if you plug in your touchscreen and it "just works").The most common ones are in the extra repository: There are a lot of touchscreen input drivers for X11 out there. If you found the corresponding node, it is likely that you will be able to get the device working. # cat /dev/input/event? # replace ? with the event numbersįor every of your event nodes while touching the display. That means there exists a /dev/input/event* node for your device. This article assumes that your touchscreen device is supported by the kernel (e.g. Input works basically as expected and I can work around it using other gamepad modes, so it’s not a major issue, but I’d like to see if I can find a solution.Įdit: I should clarify that I’m using Retroarch 1.9.0 from the Ubuntu PPA.If you ever tried to set up a touchscreen device in linux, you might have noticed that it is either working out of the box (besides some calibration) or is very tedious, especially when it is not supported by the kernel. : Pad #0 (/dev/input/event9) supports 0 force feedback effects. : Found joypad driver: “udev”.Īnd the same controller in wireless XInput mode: : Pad #0 (/dev/input/event9) supports 16 force feedback effects.

: Pad #0 (/dev/input/event9) supports force feedback. I would provide logs but the only difference I see in the logs is during force feedback detection. I don’t have any other wireless Xinput devices to test with, so I can’t be sure if it’s something about the 8Bitdo controllers specifically or XInput generally. I’ve tried them in wireless DInput and wired Xinput modes, and the issue doesn’t occur in these modes. This only affects these controllers in wireless XInput mode. When I connect these controllers(and M30 and an SN30) over Bluetooth in XInput mode, Retroarch takes much longer to launch, and afterwards thumbnails and other assets don’t load in the menu. Hoping someone here can help me diagnose some strange issues I’m having with 8Bitdo controllers in Retroarch on Linux (Specifically Kubuntu 20.04).
