Public bug reported: Im seeing screen tearing occasionally using an i915 graphics device on a stock install on Ubuntu 24.04
Seems to coincide with the following outputs: i915 0000:00:02.0: [drm] *ERROR* Atomic update failure on pipe A (start=150495 end=150496) time 333 us, min 1073, max 1079, scanline start 1065, end 10857 i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun Not much to go on sadly (apologies). Note that this was also a problem on 22.04 but appears to have been resolved. This appears to be a regression therefore ProblemType: Bug DistroRelease: Ubuntu 24.04 Package: xorg 1:7.7+23ubuntu3 ProcVersionSignature: Ubuntu 6.8.0-35.35-generic 6.8.4 Uname: Linux 6.8.0-35-generic x86_64 ApportVersion: 2.28.1-0ubuntu3 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CasperMD5CheckResult: pass CompositorRunning: None CurrentDesktop: ubuntu:GNOME Date: Sun Jun 9 15:49:19 2024 DistUpgraded: Fresh install DistroCodename: noble DistroVariant: ubuntu ExtraDebuggingInterest: Yes, including running git bisection searches GraphicsCard: Intel Corporation CometLake-H GT2 [UHD Graphics] [8086:9bc4] (rev 05) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company CometLake-H GT2 [UHD Graphics] [103c:8784] InstallationDate: Installed on 2024-05-06 (34 days ago) InstallationMedia: Ubuntu 24.04 LTS "Noble Numbat" - Release amd64 (20240424) MachineType: HP HP ZBook Fury 15 G7 Mobile Workstation ProcEnviron: LANG=en_US.UTF-8 PATH=(custom, no user) SHELL=/bin/bash TERM=xterm-256color XDG_RUNTIME_DIR=<set> ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-6.8.0-35-generic root=/dev/mapper/ubuntu--vg-ubuntu--lv ro quiet splash vt.handoff=7 SourcePackage: xorg Symptom: display UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 01/03/2023 dmi.bios.release: 12.0 dmi.bios.vendor: HP dmi.bios.version: S92 Ver. 01.12.00 dmi.board.name: 8783 dmi.board.vendor: HP dmi.board.version: KBC Version 16.4E.00 dmi.chassis.type: 10 dmi.chassis.vendor: HP dmi.ec.firmware.release: 22.78 dmi.modalias: dmi:bvnHP:bvrS92Ver.01.12.00:bd01/03/2023:br12.0:efr22.78:svnHP:pnHPZBookFury15G7MobileWorkstation:pvr:rvnHP:rn8783:rvrKBCVersion16.4E.00:cvnHP:ct10:cvr:sku9VS27AV: dmi.product.family: 103C_5336AN HP ZBook dmi.product.name: HP ZBook Fury 15 G7 Mobile Workstation dmi.product.sku: 9VS27AV dmi.sys.vendor: HP version.compiz: compiz N/A version.libdrm2: libdrm2 2.4.120-2build1 version.libgl1-mesa-dri: libgl1-mesa-dri 24.0.5-1ubuntu1 version.libgl1-mesa-glx: libgl1-mesa-glx N/A version.xserver-xorg-core: xserver-xorg-core 2:21.1.12-1ubuntu1 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev N/A version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:22.0.0-1build1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20210115-1build1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.17-2build1 ** Affects: xorg (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug corruption noble ubuntu wayland-session -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2068844 Title: Screen tearing on i1915 driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/2068844/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
