#310 Touchscreen in Lenovo X1 Yoga [056a:503e] not supported

[Mike F]

Symptoms: Hardware is to all appearances detected and initialized, but does not respond to touch, stylus, or eraser input. Hardware has been verified to work in Windows 10. Manually setting the screen bounds wth "xinput_calibrator --porecalib" did not make any difference.

Version of kernel is 4.4.1, version of xf86-input-wacom is 0.30. Running evemu-record (suggested by whot on IRC) does not capture any events, regardless of whether X is running or not.

Here's the info dump. X log is attached. Using the stock 50-wacom.conf for X11. Adding Input Device sections for Pen, Tich, and Eraser with sepecific device file options did not help, so I removed them.

Saw this requested in #307, so I'm adding it:

for F in /sys/bus/hid/drivers/wacom/*/report_descriptor; do echo $F; hexdump -C $F; done > /tmp/descriptors.txt

[Mike F]

Also, the complete /proc/bus/input/devices

hid-recorder output for /dev/hidraw0 (touch) and /dev/hidraw1 (stylus) inside of X windows.

[Jason Gerecke]

Based on the hid-recorder output, it looks like the device is sending events with an unexpected report ID. Instead of having the ID specified for the generic HID packets, the ID is of the "vendor defined" HID packets that the driver can't automatically decode. That's really odd since since most devices use the former automatically... I'll see if I can come up with a way to switch the device mode....

In the meantime, perhaps try entering the BIOS and seeing if the pen/touchscreen work there. Usually the pen or touchscreen will work properly in the BIOS, and that should be using generic HID reports. Entering the BIOS should do the necessary mode switch, and (very unlikely, but maybe) the effect of the mode switch may even persist across reboot.

[Mike F]

Unfortunately, the BIOS is keyboard only. The touchpad. trackpoint, and touchscreen are not supported in BIOS. I tried booting into Windows and rebooting into Linux to see if the initialized touchscreen would "stick", but that didn't change anything.

I noticed on the Lenovo forums that there is a firmare update to fix issues with the touschscreen failing to respond:
https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/X1-Yoga-Touch-Screen-No-Longer-Working/td-p/2269132
If your theory is correct, it might have something to do with this (Windows) issue -- it could be that the touchscreen mode is not being set correctly in firmware. I am going to apply the firmare upgrade in Windows (shudder) and will post with an update.

[Mike F]

Firmware upgraded. No change. Attached is the hid-recorder output post-firmware upgrade. I also included output from hid-recorder -d, though it probably won't be any different.

Did you hard reset the beast?

Worked until I went back into windows on its little brother (yoga 260; OpenSuse Tumbleweed)

[Mike F]

The hard reset worked. Thanks, mabawsa.

The touchscreen is now responding. For future reference, the fix is to apply the firmware update and do a hard reset.

[Jason Gerecke]

Good to know that the hard reset worked for you as well (see mabawsa's bug [#307]). I'm still going to see if I can find a way to change the mode through software since you shouldn't have to hard reset after booting into Windows :D

[Jason Gerecke]

I've made a patch which I think will do the trick. You can find the updated sources on my Github to try out. If you're not familiar with building and installing the input-wacom driver, you can find instructions here.

After installing the driver, reboot into Windows, and then back into Linux. If all goes well, the pen and touch should start working again. Let me know either way :)

[Mike F]

Seems to work.

I don't use Windows much, and rarely even reboot, so I don't know if it required a hard reset before (or if the firmware fixed it).

Some notes on the install: I'm using 4.4.1, and the 'sudo make install' failed with the following errors:
At main.c:222:
- SSL error:02001002:system library:fopen:No such file or directory: bss_file.c:169
- SSL error:2006D080:BIO routines:BIO_new_file:no such file: bss_file.c:172
sign-file: certs/signing_key.pem: No such file or directory

I'm guessing this has to do with some sort of kernel build process over at Ubuntu (I got the kernel and headers from the Ubuntu mainine PPA).

I manually copied the driver files into place, which worked fine.

[Jason Gerecke]

Fixed upstream by commit 326ea2a (due for Linux 4.6) and in input-wacom by commit 61745a2 (due for input-wacom 0.31.0 or input-wacom 0.32.0 depending on timing).

[Jason Gerecke]

Fix available in Linux 4.6 and input-wacom 0.31.0
