Public bug reported:
Device Information:
- Laptop Model: Daffodil Computers Ltd. DC253D
- OS: Ubuntu 26.04 LTS
- Touchpad Device Name: SYNA3602:00 093A:0255 Touchpad
- Touchpad IDs: bus 0x18, vendor 0x93a, product 0x255
Problem Description:
The SYNA3602 touchpad on this chassis features dedicated physical left and
right buttons. Under GNOME / libinput, the default software click emulation
('areas' or 'fingers') misinterprets button presses and drops BTN_RIGHT events,
preventing right-clicks from registering.
Verified Fix:
Setting the click method to 'none' resolves the issue completely and allows
physical BTN_LEFT and BTN_RIGHT events to pass through directly.
Suggested Quirk:
