Public bug reported: The laptop shipped with Lenovo's 6.5.0-1019-oem, but upon upgrades switched to 6.8.0-47-generic which is generally preferred because 6.5-oem is no longer seeing updates.
However, there is a regression that Fn+D Lenovo Privacy Guard does not switch correctly on after the laptop has been connected to an external display, and detaching from the external display does not help. Normal behavior is possible only after rebooting with no external screen attached. ## Test Case Laptop model: Lenovo Thinkpad T14s Gen 5 (Intel) with vendor support Ubuntu 22.04 LTS (oem-sutton-carr-meta) 1. Boot to desktop, check that Fn+D is functional both to turn the feature on and off 2. Attach external display, and try again. 3. Detach external display, try again. 4. Reboot, and try again. ## Expected Behavior Fn+D works as intended in all cases. This is how it works with 6.5.0-1019-oem. ## Actual Behavior In the case of 2. and 3., Fn+D only results in a "flashing" Privacy Guard being activated but immediately deactivated, so that it does not stay on. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu82.6 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: secto10 1765 F.... pulseaudio /dev/snd/controlC1: secto10 1765 F.... pulseaudio CRDA: N/A CasperMD5CheckMismatches: ./.disk/casper-uuid-oem ./boot/grub/efi.img ./boot/grub/grub.cfg ./casper/initrd CasperMD5CheckResult: fail CurrentDesktop: ubuntu:GNOME DistributionChannelDescriptor: # This is the distribution channel descriptor for the OEM CDs # For more information see http://wiki.ubuntu.com/DistributionChannelDescriptor canonical-oem-sutton-jammy-amd64-20240409-800 DistroRelease: Ubuntu 22.04 InstallationDate: Installed on 2024-04-23 (180 days ago) InstallationMedia: Ubuntu 22.04 LTS "Jammy Jellyfish" - pc-sutton-jammy-amd64-20240409-800 MachineType: LENOVO 21LSCTO1WW Package: linux-hwe-6.8 ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-6.8.0-47-generic root=UUID=cd7231e8-b1db-45c4-aaa0-e396d0ff90b7 ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 6.8.0-47.47~22.04.1-generic 6.8.12 RelatedPackageVersions: linux-restricted-modules-6.8.0-47-generic N/A linux-backports-modules-6.8.0-47-generic N/A linux-firmware 20220329.git681281e4-0ubuntu3.34 Tags: jammy wayland-session Uname: Linux 6.8.0-47-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 08/07/2024 dmi.bios.release: 1.7 dmi.bios.vendor: LENOVO dmi.bios.version: N46ET17W (1.07 ) dmi.board.asset.tag: Not Available dmi.board.name: 21LSCTO1WW dmi.board.vendor: LENOVO dmi.board.version: Not Defined dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.ec.firmware.release: 1.4 dmi.modalias: dmi:bvnLENOVO:bvrN46ET17W(1.07):bd08/07/2024:br1.7:efr1.4:svnLENOVO:pn21LSCTO1WW:pvrThinkPadT14sGen5:rvnLENOVO:rn21LSCTO1WW:rvrNotDefined:cvnLENOVO:ct10:cvrNone:skuLENOVO_MT_21LS_BU_Think_FM_ThinkPadT14sGen5: dmi.product.family: ThinkPad T14s Gen 5 dmi.product.name: 21LSCTO1WW dmi.product.sku: LENOVO_MT_21LS_BU_Think_FM_ThinkPad T14s Gen 5 dmi.product.version: ThinkPad T14s Gen 5 dmi.sys.vendor: LENOVO ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Affects: linux-hwe-6.8 (Ubuntu) Importance: Undecided Status: New ** Affects: linux (Ubuntu Jammy) Importance: Undecided Status: New ** Affects: linux-hwe-6.8 (Ubuntu Jammy) Importance: Undecided Status: New ** Tags: apport-collected jammy wayland-session ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags added: apport-collected jammy wayland-session ** Description changed: The laptop shipped with Lenovo's 6.5.0-1019-oem, but upon upgrades switched to 6.8.0-47-generic which is generally preferred because 6.5-oem is no longer seeing updates.
