Ciro, you have reported "works for me" but you have not confirmed that you are actually trying to reproduce the bug. The problem occurs when using modeset=1. You do not mentioned that here or in your related answer on askubuntu
If you are not using modeset=1, which is essential for people using Optimus who want to avoid tear-free graphics, then please clarify. This bug still exists for me, on both of my ThinkPads, and also with Fedora 27. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1714881 Title: no gdm3 greeter with nvidia quadro and modeset=1, discrete nvidia (not optimus) To manage notifications about this bug go to: https://bugs.launchpad.net/gdm/+bug/1714881/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
