Happy to confirm that I am typing this from the laptop running a fresh
Ubuntu 18.10 installation. The only snag I had was after the installer
completes, it doesn't want to pop up the grub menu (goes straight into
booting Ubuntu), which would prompt a crash due to the grub cmd not
being in place. Yo
My USB install stick had 18.04 on it, can confirm editing the installer
line enabled keyboard/touchpad no issues in the installer; however, I am
shooting for 18.10 for this laptop. Just adding the confirm here that it
works for 18.04 kernel as well. Will update shortly on 18.10 fresh
install.

Okay, just went back over some things to confirm in case anyone else is
encountering this issue. First, here's my setup:
1. Lenovo 330s-15arr with BIOS version 7WCN28WW.
2. BIOS settings are default for the most part (UEFI boot, etc).
With the above BIOS version, booting into Ubuntu with noapic l
Hi Kenji,
My last post went in before seeing your last post. Just tried mine with
STOCK kernel, removing noapic line and replacing it with
ivrs_ioapic[32]=00:14.0. Boom, everything works. Touchpad, keyboard,
wireless, sound. Looks like the ELAN acpi ID edit may not be needed?
Time to do some play
Hi Kenji,
I too had 7WCN27WW and went through the exact same mess of having to
open it up to reset BIOS. I just noticed they have 7WCN28WW up and
flashed it, but now my keyboard isn't working at all except to bring up
BIOS menu and THEN fail there as well. Something majorly screwy going on
with th
So far, my wifi has worked consistently, but maybe I am just lucky.
Considering the random nature of the keyboard, it makes me wonder if
some of us seeing ELAN in dmesg and some not is also pure luck of the
draw on that bootup as well.

Hi Kenji,
Compiled the 4.18 kernel last night with the proposed changes, but have
no luck. In fact, I have noticed that my keyboard doesn't work 1 out of
3 or so boots either.
I also attempted this by adding additional ACPI IDs based on how people
were doing it in the Github history for the file
Hello,
Tried this kernel but saw no change in behavior.
Earlier, someone posted this:

Hi Patrick,
I have the 330s-15ARR. What references are you seeing? I will check on
my side. Any particular boot options you're passing like noapic?
Thanks!

Hi kaihengfeng,
Tried the hardcoded kernel on 18.04, verified the following:
1. Machine still won't boot without noapic,
2. Touchpad doesn't work, dmesg | grep -i i2c and dmesg | grep -i elan doesn't
give any indication that it detected the device,
3. Confirmed with uname -a that I was running t
I would like to add that I am encountering the same issue with ELAN469D.
Tried with kernel v4.19 with no changes, not seeing it in dmesg. Please
let me know if there is any way I can assist with testing.
Thanks!
