 Posted: Tue Jun 20, 2017 6:28 pm Post subject: [SOLVED] ASUS Zenbook Pro UX501 Touchpad not recognized (v2) |
 |
|
I posted about this a while back, but got sidetracked, did a full new install, and am back now and able to work on this some more, so I'm starting a new thread. In short, I have a new-ish ASUS UX501 Zenbook Pro. I've been fighting with it for months trying to get the touchpad working. I can boot into an Ubuntu liveUSB and the touchpad works. Right now I have a fresh install with little more on it besides the kernel and Xorg. In X I have a working touchSCREEN but not touchPAD. To remove any dependency on X, I can test it on boot, prior to unlocking my root drive: If I wiggle my finger on the touchpad, I get the "rng initialization" message, but as of right now, that is not happening, and the device is not present under /sys/class/input.
I am glad to provide any more info as requested, and more than happy to do some trial and error testing as suggested. I have alread tried adding all of the configs noted here:

Thanks in advance for anyone's time in working on this. I am afraid my new laptop will be old technology by the time I get it working. :'(

I imagine that the zenbook peripherals are on the I2C bus (intel LPSS), in which case, you might be missing the correct LPSS drivers. Looking at your kernel config I suggest you might need to enable CONFIG_MFD_INTEL_LPSS_PCI. You can confirm the driver is loaded, and indeed what the ubuntu livecd is using with lspci -k.
After that, it looks like the actual HID drivers you have already found and enabled.

This has fixed it! Unfortunately, I somehow have lost my touchscreen. The Silicon Integrated Systems Corp. line has completely gone from my lsusb, and I'm not sure how I've done that. I tried simply rebuilding the kernel without the MFD_INTEL_LPSS_PCI to see if it was related, but it does not seem to be the culprit. I've apparently changed something else along the way that killed it.
Anyways, thanks so much for your help Telemin, you hit the nail right on the head. I'll keep messing around with the touchscreen, but the touchpad was the real showstopper.
Update: Touchscreen issue was hardware and was easily resolved. I've got a working laptop! |
