if Fn+F6 doesn't bring it up. then you should try to install updated firmware via Windows Asus driver updater, or attempting to use fwupd:
sudo fwupdmgr refresh sudo fwupdmgr update But given no touchpad appears visible, i'm not sure how to figure out which one it is, and what is missing to support it. Do you know the full touchpad vendor and model number? I.e. from windows info, or from bios settings / hardware spec sheets? ** Changed in: linux-signed-hwe-5.13 (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-hwe-5.13 in Ubuntu. https://bugs.launchpad.net/bugs/1965878 Title: touchpad dosen't be detected asus f553m Status in linux-signed-hwe-5.13 package in Ubuntu: Incomplete Bug description: model:laptop asus f553m issue: lubuntu 20.04 dosen't reveal touchpad Description: Ubuntu 20.04.4 LTS Release: 20.04 ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.13.0-37-generic 5.13.0-37.42~20.04.1 ProcVersionSignature: Ubuntu 5.13.0-37.42~20.04.1-generic 5.13.19 Uname: Linux 5.13.0-37-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.20.11-0ubuntu27.21 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: LXQt Date: Tue Mar 22 09:14:39 2022 InstallationDate: Installed on 2022-01-10 (71 days ago) InstallationMedia: Lubuntu 20.04.4 LTS "Focal Fossa" - Release amd64 (20220223) SourcePackage: linux-signed-hwe-5.13 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.13/+bug/1965878/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
