Hello guys another update from me. I saw that tjis thread is shared across multiple distro forums and because I tested 4 I would like to post it here for feuture reference.
Ubuntu - working but with grub parametres from comment #96, sadly no gestures are available (nor will be by libinput and touchpad-gestures library because they just can't reckognize them) Mint - same as linux Redhat - working but clicks are inverted for me lol (nothing on settings can chnage it but I guess that you can change it somehow tbh didnt want to bother with it) Kali - same as ubuntu but the touchpad is VEEERY snesitive and everything will trigger touch, multiple times while i was writing something i was iterulted by a click and this cannot be changed. For some reason ubuntu is better. Also it cant support gestures only click and pointera. I got in contact with libinput creator and after some testibg we realised that it can onky capture point devices and click events, nothing multitouch. Also every gestures on xinputlist are displayed as n/a Arch - My biggest surprise and I was so happy to boot it on arch because it works flawlessly. Not only that touchpad works (with hack) buz the gestures of scrolling got automatically reckognized, i tried as much as i can to trigger accidental clicks but couldnt do it, only thing is that it comes with touch to click disabled which was a quick fix.I think that it is compatible with libinput or other gestures because its reckongized as ELAN not just pointer device. This will be my main distro on this laptop. Hope that this was helpfull i'll also link other newer lenovo devices that I test so that this problem does not limit to thinkbooks. Again this is just my experience for you it might be different. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem-5.6 in Ubuntu. https://bugs.launchpad.net/bugs/1861610 Title: 'Elan touchpad' not detected on 'Lenovo ThinkBook 15 IIL' Status in linux package in Ubuntu: Fix Released Status in linux-oem-5.6 package in Ubuntu: Fix Released Status in linux-oem-osp1 package in Ubuntu: Invalid Status in linux source package in Bionic: Fix Released Status in linux-oem-5.6 source package in Bionic: Invalid Status in linux-oem-osp1 source package in Bionic: Fix Released Status in linux source package in Eoan: Fix Released Status in linux-oem-5.6 source package in Eoan: Invalid Status in linux-oem-osp1 source package in Eoan: Fix Released Status in linux source package in Focal: Fix Released Status in linux-oem-5.6 source package in Focal: Fix Released Status in linux-oem-osp1 source package in Focal: Invalid Bug description: [SRU Justification] [Impact] Touchpad function unavailable on some platforms with new ELAN touchpad HIDs.
