You seem to be experiencing recurring kernel crashes in the 'nouveau' driver.
Rather than waiting for a fix I suggest just installing the proprietary Nvidia driver from the 'Additional Drivers' app. ** Summary changed: - the screen is hanging frequently and i am unable to perform any typing work on the screen due to the huge delay between my typing and characters appearing on the screen + nouveau keeps crashing in nvkm_pmu_init ** Package changed: xorg (Ubuntu) => linux (Ubuntu) ** Tags added: nouveau -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1895502 Title: nouveau keeps crashing in nvkm_pmu_init Status in linux package in Ubuntu: New Bug description: screen brightness automatically gets full even if I reduce it ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: xorg 1:7.7+19ubuntu7.1 ProcVersionSignature: Ubuntu 4.15.0-76.86-generic 4.15.18 Uname: Linux 4.15.0-76-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.9 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CompositorRunning: None CurrentDesktop: ubuntu:GNOME Date: Mon Sep 14 09:59:45 2020 DistUpgraded: Fresh install DistroCodename: bionic DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: Intel Corporation UHD Graphics 620 [8086:5917] (rev 07) (prog-if 00 [VGA controller]) Subsystem: Lenovo UHD Graphics 620 [17aa:3963] Subsystem: Lenovo GP108M [GeForce MX150] [17aa:3963] InstallationDate: Installed on 2019-01-10 (612 days ago) InstallationMedia: Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 174f:241a Syntek Bus 001 Device 003: ID 0cf3:e500 Atheros Communications, Inc.
