I'm not sure we should be looking in gdm here. Tim has mentioned several times that kernel 4.15.0-36-generic works and kernel 4.15.0-38 fails.
I wonder though, if the Nvidia driver might have just failed to build for the newer kernels. ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Summary changed: - gdm3: Xorg loads, no display on nvidia 390.77-0ubuntu0.18.04.1 + Xorg loads, no display on nvidia 390.77-0ubuntu0.18.04.1 ** Summary changed: - Xorg loads, no display on nvidia 390.77-0ubuntu0.18.04.1 + Xorg loads, no display on nvidia 390.77-0ubuntu0.18.04.1 using kernel 4.15.0-38, but 4.15.0-36-generic works -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1799994 Title: Xorg loads, no display on nvidia 390.77-0ubuntu0.18.04.1 using kernel 4.15.0-38, but 4.15.0-36-generic works To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1799994/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
