Second touch display not working

Hi everyone! I’m having a bit of an interesting issue:

I’ve installed the 18.04 LTS version of Budgie on an Asus Zenbook Duo, and it has been working well for the past couple of weeks. However, as of today, the second displays touch and pen capabilities have completely stopped working. Xinput output below:

⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ ELAN1207:00 04F3:310E Touchpad          	id=13	[slave  pointer  (2)]
⎜   ↳ Logitech M187                           	id=10	[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)]
    ↳ Asus WMI hotkeys                        	id=14	[slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard            	id=15	[slave  keyboard (3)]
    ↳ Logitech M187                           	id=16	[slave  keyboard (3)]
    ↳ USB2.0 HD IR UVC WebCam: USB2.0         	id=12	[slave  keyboard (3)]
    ↳ USB2.0 HD IR UVC WebCam: USB2.0         	id=11	[slave  keyboard (3)]

Previously, the touchpad (and the pen, after it was used) would appear under the Virtual core pointer list.

I’ve already reinstalled Budgie (completely reformatted the partition, and re-partitioned the drive), and found that while the pen would work in the ‘Try Budgie’ boot option, it stopped working after a full install.

Any advice would be appreciated! Also, if this is the wrong place to ask, let me know.

Interesting issue.

Just wondering if the latest kernel has broken things.

You can change to an earlier kernel via Grub - advanced options (press escape, space or shift immediately when booting if you dont normally see the Grub screen)

That looks like it fixed it! In Xinput, the touch screen is showing up again.

Thanks! I’ll change the default boot kernel for now

Please remember to report the broken kernel to launchpad otherwise the kernel devs will not be aware … thus cannot fix things

Got it, will do. Thanks for your help
