[Kernel-packages] [Bug 1936708] Re: Wobbly graphics on built-in display since linux-image-5.11.0-22-generic
Had to disable secure boot to get it to boot, but yes, we are working! Running 5.11.0-1034-generic and no wobbly graphics.

OK, linux-modules was installed but linux-modules-extra was not. I installed that package and booted from 5.11.0-34 and the distortion is back. I removed it, rebooted, and still the distortion was there, but the desktop and network was working. I cannot repeat what happened the first time I booted 5.11.0-34, but it definitely was that version as journalctl --boot=-6 shows it. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem-5.13 in Ubuntu. https://bugs.launchpad.net/bugs/1936708 Title: Wobbly graphics on built-in display since linux- image-5.11.0-22-generic Status in linux package in Ubuntu: Confirmed Status in linux-oem-5.13 package in Ubuntu: Invalid Status in linux source package in Focal: Won't Fix Status in linux-oem-5.13 source package in Focal: Fix Committed Status in linux source package in Hirsute: Confirmed Status in linux-oem-5.13 source package in Hirsute: Invalid Status in linux source package in Impish: Confirmed Status in linux-oem-5.13 source package in Impish: Invalid Bug description: == SRU Justification == [Impact] Wobbly graphics after a kernel update.

Installed linux-image-5.11.0-34-generic from proposed. It seems to fix the issue with graphics distortion from the decryption prompt onwards. Unfortunately it doesn't work very well after that.

Since booting from linux-image-5.11.0-22-generic, the built-in display is unusable, with wobbling horizontal stripes from the disk decryption prompt onwards: https://www.youtube.com/watch?v=LyRTuPzCe2I HDMI output works fine. If I boot from linux-image-5.11.0-18-generic instead, all is well. If I use Recovery mode and continue bootup, it's usable but there's no HDMI output. I think others may be having this issue too: https://askubuntu.com/questions/1351188/weird-graphical-glitches-appears-only-on-integrated-display-on-any-ubuntu-base# ProblemType: Bug DistroRelease: Ubuntu 21.04 Package: linux-image-5.11.0-22-generic 5.11.0-22.23 ProcVersionSignature: Ubuntu 5.11.0-22.23-generic 5.11.21 Uname: Linux 5.11.0-22-generic x86_64 ApportVersion: 2.20.11-0ubuntu65.1 Architecture: amd64 AudioDevicesInUse: USERPID ACCESS COMMAND /dev/snd/controlC1: alex 1598 F pulseaudio /dev/snd/controlC0: alex 1598 F pulseaudio CasperMD5CheckResult: unknown CurrentDesktop: KDE Date: Sat Jul 17 09:50:31 2021 InstallationDate: Installed on 2021-01-03 (194 days ago) InstallationMedia: Ubuntu 20.10 "Groovy Gorilla" - Release amd64 (20201022) MachineType: LENOVO 80DU ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-5.11.0-22-generic root=/dev/mapper/vgubuntu-root ro quiet splash vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-5.11.0-22-generic N/A linux-backports-modules-5.11.0-22-generic N/A linux-firmware 1.197.2 SourcePackage: linux UpgradeStatus: Upgraded to hirsute on 2021-05-22 (55 days ago) dmi.bios.date: 08/18/2014 dmi.bios.release: 1.49 dmi.bios.vendor: LENOVO dmi.bios.version: 9ECN31WW(V1.14) dmi.board.asset.tag: 31900058WIN dmi.board.name: Lenovo Y70-70 Touch dmi.board.vendor: LENOVO dmi.board.version: 31900058WIN dmi.chassis.asset.tag: 31900058WIN dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Lenovo Y70-70 Touch dmi.ec.firmware.release: 1.49 dmi.modalias: dmi:bvnLENOVO:bvr9ECN31WW(V1.14):bd08/18/2014:br1.49:efr1.49:svnLENOVO:pn80DU:pvrLenovoY70-70Touch:rvnLENOVO:rnLenovoY70-70Touch:rvr31900058WIN:cvnLENOVO:ct10:cvrLenovoY70-70Touch: dmi.product.family: IDEAPAD dmi.product.name: 80DU dmi.product.sku: LENOVO_MT_80DU_BU_idea_FM_Lenovo Y70-70 Touch dmi.product.version: Lenovo Y70-70 Touch dmi.sys.vendor: LENOVO ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug hirsute wayland-session ** Description changed: Lenovo laptop with Intel + Nvidia graphics. - Since booting from linux-image-5.11.0-22-generic, the built-in display is unusable, with wobbling horizontal stripes from the disk decryption prompt onwards: https://www.youtube.com/watch?v=LyRTuPzCe2I HDMI output works fine.
