Device Information

• Laptop Model: Lenovo Yoga 730-15IWL (Type 81JS)
• Touchscreen Device: WCOM5169:00 056A:5169 (Wacom HID 5169)
• Connection: I2C HID v1.00

Problem Description

The touchscreen is detected by the kernel and creates input devices, but produces zero touch events. The device appears in dmesg without errors and creates both "Wacom HID 5169 Pen" and "Wacom HID 5169 Finger" input devices, but touching the screen generates no input events.

System Information

• Distribution: Fedora 42
• Kernel: 6.17.4-200.fc42.x86_64
• Desktop Environment: Cinnamon
• Wacom Driver Version: v2.00

Device ID Not in Supported List

$ modinfo wacom | grep 5169

Returns nothing - device ID 5169 is not in the wacom driver's supported device list.

What We've Tried

• ✗ Tested both event12 (Pen) and event13 (Finger) - no events
• ✗ Disabled touch_arbitration parameter - no effect
• ✗ Tested in tablet mode (360° fold) - screen rotates but touch still doesn't work
• ✗ Attempted to build input-wacom from source - fails to compile on kernel 6.17.4 with from_timer API errors
• ✓ Tablet mode sensor works correctly
• ✓ No errors in dmesg

Related Reports

• Arch Wiki Talk page mentions another Yoga 730-15IWL owner with the same touchscreen issue (quote: "I couldn't get touchscreen to work, although this is probably an issue with my hardware, since it didn't work on Windows either")
• Ubuntu bug #2023580 reports Yoga 730-13IWL touchscreen only works with stylus, not fingers
• Arch Wiki main article for this laptop model

Expected Behavior

Touching the screen should generate input events visible via evtest and should function as a touchscreen input device.

Actual Behavior

Zero touch events are generated despite the device being detected and creating input devices without errors.

Request

Please add support for Wacom device ID 5169 (056A:5169) to enable touchscreen functionality on Lenovo Yoga 730-15IWL laptops.
