OK, after compiling 5.0.7 mainline + Ubuntu Patches + this patch from here (https://patchwork.freedesktop.org/patch/296411/) to fix the link training issue for my laptop panel, I am able to boot with modesetting.
Now I *am* noticing the problem. As others have suggested, bending back the laptop panel on it's hinge "resets" the keyboard and trackpad, then I can bend it back to a normal position and everything starts working. One other thing worth mentioning is that the problem also exhibits itself in lightdm, not just gdm3. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1822394 Title: [Dell BIOSes dated 27 Mar 2019] laptop keyboard & touchpad not working at gdm screen after boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1822394/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
