[SOLVED] Touchpad not working after install [Lenovo IdeaPad Flex3]

I was able to install Arch on the laptop Lenovo IdeaPad Flex 3 11ADA05. However, the touchpad is not working from the start. The USB does work. Arch was the 4th distro I tried to install on this laptop as the others did not see the eMCC drive to install on. The touchpad worked on all of the previous liveUSBs (MX, Manjaro), but not on the penultimate one which was Ubuntu.

The touchpad seems to be detected. I believe that's the ELAN238E:00 04F3:2A78.

xinput enable "ELAN238E:00 04F3:2A78"

did not work.

[root]# xinput --list

Re: [SOLVED] Touchpad not working after install [Lenovo IdeaPad Flex3]

Did you check if Xorg detected it correctly, as described here: https://wiki.archlinux.org/title/Libinput ?

grep -e "Using input driver 'libinput'" /var/log/Xorg.0.log

It should output something like that:

[    28.799] (II) Using input driver 'libinput' for 'Power Button'
[    28.847] (II) Using input driver 'libinput' for 'Video Bus'
[    28.853] (II) Using input driver 'libinput' for 'Power Button'
[    28.860] (II) Using input driver 'libinput' for 'Sleep Button'
[    28.872] (II) Using input driver 'libinput' for 'AT Translated Set 2 keyboard'
[    28.878] (II) Using input driver 'libinput' for 'SynPS/2 Synaptics TouchPad'
[    28.886] (II) Using input driver 'libinput' for 'TPPS/2 IBM TrackPoint'
[    28.895] (II) Using input driver 'libinput' for 'ThinkPad Extra Buttons'

Also make sure that you have xf86-input-libinput and xorg-xinput installed.

Re: [SOLVED] Touchpad not working after install [Lenovo IdeaPad Flex3]

Yes, it is detected by Xorg (assuming it is ELAN238E:00 04F3:2A78):

[root]# grep -e "Using input driver 'libinput'" /var/log/Xorg.0.log
[     4.072] (II) Using input driver 'libinput' for 'Power Button'

[     4.486] (II) Using input driver 'libinput' for 'Compx 2.4G Receiver Consumer Control'

And yes, both xf86-input-libinput and xorg-xinput were installed.

Re: [SOLVED] Touchpad not working after install [Lenovo IdeaPad Flex3]

Touchpad works in BIOS version FPCN24WW. I found a similar problem on a different forum ( https://newbedev.com/elantech-touchpad- … arch-linux ) where it was suggested to make changes to GRUB. However, I'm using systemd-boot because I had issues booting with GRUB ( but I'll consider giving it a try again if nothing else works).

Is there a way to make an equivalent change in systemd-boot as was done for GRUB in the link I posted?

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

Re: [SOLVED] Touchpad not working after install [Lenovo IdeaPad Flex3]

I have tried booting with:

[root]# cat /proc/cmdline
initrd=\amd-ucode.img initrd=\initramfs-linux.img root=PARTUUID=3b81b8a9-1206-2448-8562-91d7a90c0007 rw i8042.reset

and

[root]# cat /proc/cmdline
initrd=\amd-ucode.img initrd=\initramfs-linux.img root=PARTUUID=3b81b8a9-1206-2448-8562-91d7a90c0007 rw i8042.kbdreset=1

but neither worked.

Re: [SOLVED] Touchpad not working after install [Lenovo IdeaPad Flex3]

Issue solved by reinstalling Windows 10 and downgrading the Lenovo BIOS to FPCN21WW. Touchpad still works after reinstalling Linux.
