Touchscreen tap-to-click behaviour after changing to x11

Hello everyone!

I’m relatively new to the whole Linux game, and as for now nearly everything is working fine, only one thing, which i think is configuration, but i dont really know what exactly or where to search.

IS:
hardware:

  • lenovo thinkcentre (tested: m93p, m910q) or ops module (2 types tested)
  • iiyama touchscreen or noname touchscreen (both usb, no special drivers) (only one screen attached)

software:

  • manjaro-gnome-24.0.5-minimal-240730-linux69 (installed with open source drivers)
  • no other software installed, just the iso installation

everything works out-of-the-box, including touchscreen (tap-to-click)

now i want to use openboard and rustdesk, and these two have a limited wayland support, so i switched to x11 (etc/gdm/custom.conf → waylandenable=false)

when i do this, there is a strange behaviour:

i can click the app button top left with one finger, and then the app menu comes up i cant click with one finger, i have to use 2 fingers!

how could i change this to one finger again?

(i dont know the exact version, but ca. half a year ago it worked with the then-actual manjaro iso)

searching for this problem i tried:

  • in /etc/X11/xorg.conf.d/ there is no configuration file for the touchscreen, so i dont know what to do
  • in gnome-tweaks there is no tap-to-click option
  • dconf says tap-to-click is activated (off-restart-on-restart doesnt do anything)
  • i found this but i dont know what to do with it: arch bbs topic id 272771 as there is no conf file for the touch screen
  • i tried installing “xf86-input-evdev” (standard was libinput), no change in behaviour
  • everything else i found were problems with the synaptics touchpad on notebooks

i hope its enough information, if not i can give more.

thanks!
