So it's the same issue as this one, right? https://gitlab.freedesktop.org/drm/intel/-/issues/3714

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 with linux-image-5.11.0-22-generic 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: USER PID 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1936708/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
