20.04 Daily Build - Elan touch pad not detected.

Asked by D on 2020-03-21

Long time since I had to ask for help or advice and this is just the daily build, pre-release so it may be in the process of being fixed. I don't have a launchpad account and I'm not sure I need one.

How can I check if this is a known issue?

Hardware: Lenovo P73 with a NVIDIA RTX-5000 QMax, 64Gb RAM.

There are two issues:

1. On the USB install the screen is not correctly detected and shows garbage. When the sound for Focal Fossa being loaded is heard I close the lid (putting the laptop to sleep), open the lid, touch the power button to activate and the screen is perfect. No problems with the install after that.

2. The onboard Elan touch pad worked during the install but not after installing Ubuntu 20.04 daily build.

I used a wireless USB mouse from Vilros to navigate initially.

 sudo sh -c 'echo -n "elantech" > /sys/bus/serio/devices/serio1/protocol'
enabled the touchpad and pointer and the USB mouse still worked.

I don't know if these are transient issues and will be fixed later but I'd like to know if people think these reportable bugs or noting the issue here is enough?

I suggest you report a bug. Report your workaround too. It may help

Can't log a bug. Alt-F2 fails as it's not a program and using PID 1 fails as it's not a stable version.

Since there seems to be no other way to log a bug I guess this pitiful post will remain missed by all but you and I.

So I'll leave this as "I still need an answer" in case someone can tell me how else to log these two issues against a non-stable build.

Press CTRL + ALT + T and run:

ubuntu-bug xorg

Obviously change the package name if you can think of a more accurate one

Ok, I'll take that as an answer, even though it's not xorg. I'll hope someone will reclassify it.

Thanks actionparsnip, that solved my question.
