Can you check if you have intel-vbtn or intel-hid driver loaded? I would think intel-vbtn.
Whichever it is a good experiment with the above comment is to blacklist the module, rebuild initramfs and reboot. See if this helps. If it does then it's likely a situation of this driver starting in wrong state. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libinput in Ubuntu. https://bugs.launchpad.net/bugs/1822394 Title: [Dell BIOSes dated 27 Mar 2019, XPS 9575, Precision 5530 2-in-1] laptop keyboard & touchpad not working at gdm screen after boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libinput/+bug/1822394/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
