I recently installed Ubuntu 18.04 on my new computer (Asus-ZenBook-Pro-15-UX580GE-BO022T) and everything seems to works fine except my touchpad. After installation and first reboot the tochpad was working. I then changed additional drivers to use nvidia-driver-390 instead of xserver-xorg-video-nouveau. When changes were made and i rebooted the computer tocuhpad wasn't working anymore. (I have tried to change back to xserver instead of nvidia without luck)
xinput gives me:
~$ xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ ELAN Touchscreen id=12 [slave pointer (2)] ⎜ ↳ Lenovo Optical Mouse id=13 [slave pointer (2)] ⎜ ↳ GDX1505:00 27C6:01F1 Touchpad id=15 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Video Bus id=8 [slave keyboard (3)] ↳ Power Button id=9 [slave keyboard (3)] ↳ Sleep Button id=10 [slave keyboard (3)] ↳ ELAN Touchscreen Pen id=11 [slave keyboard (3)] ↳ USB2.0 VGA UVC WebCam: USB2.0 V id=14 [slave keyboard (3)] ↳ Asus WMI hotkeys id=16 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=17 [slave keyboard (3)]
As you can see there is a touchpad as input device.
And when i go to Settings->Devices->Mouse & Touchpad the touchepad is enabled and everything looks fine.
On the other hand, when i click
fn + f6 (enable/disable touchpad) there is a cross over the touchpad icon. No matter how many times i click, I can't enable it from here.
Hope you guys understand my problem. Tell me if you need more information.
