I just got a Lenovo Yoga 510. I've installed Fedora 25 (as dual boot with MSWindows). But the touchscreen isn't working in Wayland nor Xorg.
xinput list only shows the trackpad, keyboard, powerbutton and camera. No likely candidates seen in /proc/bus/input/devices, lspci, lsusb nor dmesg.
lsusb reports two devices (other than hubs): acer 5986:0711, which appears to be the webcam and amd 0438:7900. I've not been able to find a description for the latter. I don't see anything else which is obviously the trackpad (which is working fine) - so the AMD USB device might be that.
Under MSWindows, it seems the devices is handled by the WacomPen driver.
In Linux, running
modprobe wacom modprobe wacom_w8001 xsetwacom --list devices
produces no output.
It does seem a little strange that not only is the device unsupported by Linux, but actually seems to be invisible to Linux.
While I don't believe I'm in a position to start writing device drivers, I would like to be able to capture as much information as possible about the hardware, if nothing else to be able to describe the issue.
Does anyone have any suggestions about where else I should be looking for information about the hardware (or a solution would be nice too ;))
