[Bug 1706474] Re: gdm3 nvidia modeset=1 is broken, external screens don't work on a Thinkpad p50
I just found out about this. I wanted to get rid of the screen tearing that I observed on my Nitro AN515-53 laptop running Ubuntu 18.04.3 LTS with NVIDIA GeForce GTX 1050 Mobile GPU. I used https://askubuntu.com/a/020 and set nvidia_drm modeset=1 but then my external monitors didn't work after the reboot. So I switched from gdm3 to lightdm and that does the trick for me. -- 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/1706474 Title: gdm3 nvidia modeset=1 is broken, external screens don't work on a Thinkpad p50 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1706474/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

I should add that the "fix" I reported is only a narrow fix. The internal display works. But external displays don't work if you have nvidia drivers, gdm3 and if you are using modeset=1 -- 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/1706474 Title: gdm3 nvidia modeset=1 is broken, external screens don't work on a Thinkpad p50 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1706474/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Daniel, with the latest 17.10 the nvidia problems are now more specific and easier to reproduce. Neither of my Thinkpads gets to the login screen in discrete Nvidia mode iff modeset=1 is used. In hybrid graphics, the session starts, I suspect this is due to the intel driver being available. If I'm correct, then any machine with only an nvidia card should fail with nvidia modesetting.
