It looks like you have the nvidia kernel driver version 415 installed but no Xorg driver to match. That may be the problem.
Another problem is that the Nvidia driver version 415 is not part of Ubuntu (where did you get it from?), so this is not a valid Ubuntu bug. Please remove the driver and/or install a supported version like: sudo apt install nvidia-driver-390 ** Package changed: xorg (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1816483 Title: problem with nvidia driver Status in Ubuntu: Invalid Bug description: then i play internet video or in facebook my screen jumping or buzing how can i fix that there is line like some wrong codecs . dell ispiration 7577 ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: xorg 1:7.7+19ubuntu7.1 ProcVersionSignature: Ubuntu 4.15.0-45.48-generic 4.15.18 Uname: Linux 4.15.0-45-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia .proc.driver.nvidia.gpus.0000.01.00.0: Error: [Errno 21] Is a directory: '/proc/driver/nvidia/gpus/0000:01:00.0' .proc.driver.nvidia.registry: Binary: "" .proc.driver.nvidia.version: NVRM version: NVIDIA UNIX x86_64 Kernel Module 415.27 Thu Dec 20 17:25:03 CST 2018 GCC version: gcc version 7.3.0 (Ubuntu 7.3.0-27ubuntu1~18.04) ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CompositorRunning: None CurrentDesktop: ubuntu:GNOME Date: Mon Feb 18 22:22:31 2019 DistUpgraded: Fresh install DistroCodename: bionic DistroVariant: ubuntu DkmsStatus: nvidia, 415.27, 4.15.0-45-generic, x86_64: installed GraphicsCard: Intel Corporation Device [8086:591b] (rev 04) (prog-if 00 [VGA controller]) Subsystem: Dell Device [1028:0802] NVIDIA Corporation GP106M [GeForce GTX 1060 Mobile] [10de:1c20] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Dell GP106M [GeForce GTX 1060 Mobile] [1028:0802] InstallationDate: Installed on 2019-02-16 (2 days ago) InstallationMedia: Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) MachineType: Dell Inc.
