[Bug 1799994] Re: Xorg loads, no display on nvidia 390.77-0ubuntu0.18.04.1
For the record, I have a Lenovo P50 running Ubuntu MATE (which uses lightdm), also in am Ultradock. It is running in "Discrete" (NVIDIA) mode using nvidia-396 from the graphics-driver ppa, and had been working well since at least -34. When I upgraded to -38 (from -36), the system comes up to the greeter screen in a low resolution, and though it works, when I log in, the low resolution remains. When I boot to -36 again, same problem, but if I boot to -34, strangely, it works. When I compare the xorg.log between a "good" boot (in -34) and a "bad" boot (in -38), I can see that in the "bad" boot, it's just not finding any nvidia drivers, while in the "good" boot it is. I've been booting to -34 as a workaround, but I suspect this is the same problem as is described by the OP, and if there's anything I can do to help, please let me know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/174 Title: Xorg loads, no display on nvidia 390.77-0ubuntu0.18.04.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/174/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

OK. Next we probably want to get an idea of what gdm is doing. Please reproduce the problem, then reboot and collect the system log of the previous boot where the problem occured: journalctl -b-1 > prev_boot.txt and attach prev_boot.txt. ** No longer affects: nvidia-graphics-drivers-390 (Ubuntu) ** No longer affects: linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/174 Title: Xorg loads, no display on nvidia 390.77-0ubuntu0.18.04.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/174/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm already not running Wayland. When I was running Wayland, it started up on the internal display using the Intel driver.

[Bug 1799994] Re: Xorg loads, no display on nvidia 390.77-0ubuntu0.18.04.1
Adding nomodeset rebuilding initrd and rebooting does not fix it. The Lenovo ThinkPad W540 has no option to disable the integrated video card. The internal display is always run by the intel. I have it set to use the nvidia on external displays because that allows supporting more displays. So neither suggestions from bug 1705369 works. ** Changed in: nvidia-graphics-drivers-390 (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/174 Title: Xorg loads, no display on nvidia 390.77-0ubuntu0.18.04.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/174/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

After completely removing the nvidia drivers, rebooting, and reinstalling the nvidia drivers, even the old kernel fails to boot. This appears to be an nvidia driver issue that shows up because of the gdm3 setup where it runs two different Xorg instances. Under lightdm+gnome the displays light up normally. re-removing the kernel versions as with the new nvidia drivers on the old kernel we're still broken. ** Summary changed: - 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 + Xorg loads, no display on nvidia 390.77-0ubuntu0.18.04.1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/174 Title: Xorg loads, no display on nvidia 390.77-0ubuntu0.18.04.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/174/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

nvidia drivers build and install just fine. Starting gdm3 fails to detect displays, but Xorg does start. Stopping gdm3 and running a bare Xorg gets working displays. Restarting gdm3 and displays work. Displays light up fine with lightdm-gtk-greeter and the single Xorg instance.
