 Posted: Sun Mar 03, 2019 6:54 pm Post subject: [Solved] [Goodix Touchscreen] Libinput |
 |
|
Hello,
I have a laptop (one mix 2 yoga) with a i2c goodix touchscreen witch work perfectly with ubuntu-mate live CD, but on gentoo i'm unable to make the touchscreen as expected : It works but like a touchpad (you can't scroll by sliding finger on the screen, instead it select the text.
After search it seems that these 2 options were the right to select :
Option "Tapping" "true"
Option "TappingDrag" "true"
Now I created a file : /etc/X11/xorg.conf.d/99-touchscreen.conf
| Code: | Section "InputClass"
Identifier "TouchScreen"
MatchProduct "Goodix Capacitive TouchScreen"
Driver "libinput"
Option "Tapping" "true"
Option "TappingDrag" "true"
Option "TransformationMatrix" "0 1 0 -1 0 1 0 0 1"
EndSection |
option "TransformationMatrix" is well applied but not these 2 :
Option "Tapping" "true"
Option "TappingDrag" "true"
It seems these cannot be selected on this device as seens bellow
Tap-to-click: n/a
Tap-and-drag: n/a
full output of libinput list-devices for this device :
| Code: | Device: Goodix Capacitive TouchScreen
Kernel: /dev/input/event12
Group: 7
Seat: seat0, default
Capabilities: keyboard touch
Tap-to-click: n/a
Tap-and-drag: n/a
Tap drag lock: n/a
Left-handed: n/a
Nat.scrolling: n/a
Middle emulation: n/a
Calibration: identity matrix
Scroll methods: none
Click methods: none
Disable-w-typing: n/a
Accel profiles: n/a
Rotation: n/a

Something strange, device is listed in xinput --list as :
| Code: | | ↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)] |
full output :
| Code: | ⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech Logitech USB Optical Mouse id=10 [slave pointer (2)]
⎜ ↳ FocalTechPS/2 FocalTech Touchpad id=13 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Asus Wireless Radio Control id=7 [slave keyboard (3)]
↳ Video Bus id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ Asus WMI hotkeys id=11 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)]

This is solved as there is no problem 
first my report is false as execute xinput by ssh is evidently not the same.
Second there is no problem, touchscreen works as expected, just by example firefox who don't behave as expected is a firefox config and not a "general" config like I was thinking...
So for this point I juts have to read first line of firefox gentoo wiki :
| Code: | Enabling multitouch
Xinput2 scrolling
This brings touch scrolling and multitouch support for Firefox:
MOZ_USE_XINPUT2 environment variable has to be set to a value of 1 in /etc/env.d/80firefox, or just before launching firefox in a shell. for example:
user $MOZ_USE_XINPUT2="1" firefox |
So I just feel embarrassed , the worst is I search for the solution for hours before posting |
