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 Kernel Packages, which is subscribed to linux 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 Status in libinput package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: On a dell XPS 15 2-in-1 with the latest 1.4.0 bios, my touchpad and keyboard are unresponsive at the gdm login screen. Keyboard works to unlock encrypted harddrive before that though. If I plug in a USB keyboard or activate my bluetooth mouse, I can use those to log in, and then after logging in the laptop touchpad and keyboard work again. Logging out of the desktop results in the laptop touchpad and keyboard working on the gdm screen. Did not see this behavior before upgrading from 1.2.0 bios to 1.4.0 bios, but also had not rebooted in a while, so not sure if bios or package upgrades triggered this behavior.
