On a new XPS 15 9575 2-in-1 with BIOS 1.8.1, the symptoms are similar to comment #24. At the gdm login screen, the keyboard doesn't work at first but is OK after 20-30 seconds. The touchpad is not affected. The Linux 4.15 kernel is not affected but later ones are. I tried it with 4.18, 5.0 and 5.3 kernels. I am running Mint 19.2, which uses the Ubuntu kernels.
If I boot in recovery mode, the keyboard works on the recovery mode menu. If I then exit to normal boot, the unresponsive keyboard recurs. However, the elapsed time until it starts working again is from the initial boot. That is, if I wait 30 seconds in recovery mode before exiting to normal boot, the keyboard will then be working at the gdm screen. -- 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
