I just got a new computer, and I'm wanting to install Ubuntu. Right now I'm just running the live image from USB, and everything seems to work great...except the touchscreen.
The touchscreen works in both BIOS and Win10, so I know the hardware is good. Win10 recognizes it as:
However when I boot my 18.04 Ubuntu live usb (4.15.0-20 kernel), the touchscreen doesn't even show up at all under
lsusb. Completely missing. This is all I get under the pointers:
Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=15 [slave pointer (2)]
I've checked the syslog, and haven't found anything mentioning Elan, but I'm not really sure exactly what I'm looking for. I've tried two different ISO images (Ubuntu and Xubuntu, both 18.04).
My other computer is a 2 year old XPS 13, also with an Elan touchscreen. This is what i get from
xinput on it (same as above, except also this line just above the Synaptics):
⎜ ↳ ELAN Touchscreen id=10 [slave pointer
Likewise on the XPS I get this in
Bus 001 Device 003: ID 04f3:20d0 Elan Microelectronics Corp.
That's my only reference point, I've been searching here and elsewhere and haven't found anything about this. Any help would be greatly appreciated!
