Sorry for taking so long to get to this. I see that there's a 5.5.0 rc kernel in testing now. Can you update to that? In this week's Prioritized Bugs meeting, we decided to defer a decision. I will send a request to the test mailing list to see if they can reproduce the issue. Adding needinfo to Dee'Kej to see if 1. The 5.5.0 kernel currently building (https://koji.fedoraproject.org/koji/packageinfo?packageID=8) fixes it 2. The latest live respin (https://dl.fedoraproject.org/pub/alt/live-respins/F31-WORK-x86_64-LIVE-20191105.iso) works. The respin contains kernel 5.3.8, so that may help narrow down the version that introduced this behavior. grab a updated 20191205 (f31) or 20191206 (F30) updated iso from http://tinyurl/Live-respins do either resolve this issue? Latest libinput pre-release contains: "Touchpad fix and trackpoint speed adjustment for Lenovo T490s" [1] Perhaps related? [1] https://lists.freedesktop.org/archives/wayland-devel/2019-December/041062.html My apologies for late reply, I was stuck in personal stuff. Unfortunately I cannot test this issue anymore, since I'm no longer working for a company from which I was using the Lenovo T490s. Hopefully someone with the same model can reproduce and confirm/reject the fix. With kind regards, Dee'Kej Rejected as a Prioritized Bug since the reporter no longer has access to the affected hardware and there are no other reports. https://meetbot.fedoraproject.org/fedora-meeting/2019-12-18/fedora_prioritized_bugs_and_issues.2019-12-18-16.06.log.html#l-39 This can be reproduced on the new standard spec laptop provided by Red Hat service desk. There's also a bug for this specific to Fedora 31 https://bugzilla.redhat.com/show_bug.cgi?id=1788537 I'm not sure how Fedora manages bugs, whether or not one of these should be marked as a dupe of each other so I'll just leave this note here. Since I'm using Fedora 31 I'll attempt to use a 5.5 kernel and report back on the other bug. I can confirm that disabling TPM in the BIOS on the T490s works as a workaround for Fedora 30 running Linux 5.4.10-100. I ran into this problem on F31 today with a fresh install, but after updating to the latest packages including kernel 5.5.7-200.fc31.x86_64 the trackpad on my T490s started working properly. Disabling TPM on a T490s gets past this issue on F31 LiveCD. For those not sure how to do this: * enter your BIOS screen (hit enter on boot) * Go to "Security" section * disable "Trusted Platform Module" (typing from memory, it may not be named exactly this) * save and exit * boot to USB and install OS I couldn't find the TMP or alike setting in the BIOS. But I found a hint in BZ1634832#c23 where it is suggested to add psmouse.elantech_smbus=0 to the kernel parameter in /etc/default/grub. I'm going to dnf update first and reboot now and if that doesn't work I'm going to add the kernel parameter. After rebooting my system to the new kernel (with no other changes) I no longer have the problems that my trackball and touchpad don't work. kkleine@work ~$ uname -a Linux work 5.5.17-200.fc31.x86_64 #1 SMP Mon Apr 13 15:29:42 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux kkleine@work ~$ lsb_release -a LSB Version: :core-4.1-amd64:core-4.1-noarch Distributor ID: Fedora Description: Fedora release 31 (Thirty One) Release: 31 Codename: ThirtyOne This message is a reminder that Fedora 30 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 30 on 2020-05-26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '30'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 30 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 30 changed to end-of-life (EOL) status on 2020-05-26. Fedora 30 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
