** Description changed: On some setups, while the monitor and the gpu support display modes with pixel clocks of up to 600MHz, the link encoder might not. This prevents YCbCr444 and RGB encoding for 4k60Hz, but YCbCr420 encoding might still be possible. However, which color mode is used is decided before the link encoder capabilities are checked. This patch fixes the problem by retrying to find a display mode with YCbCr420 enforced and using it, if it is valid. Patch already got accepted upstream for linux-next: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux- next.git/commit/?id=14e4a095b29fd290a9b80f6e553adcfcf01672d1 and applies without modifications to ubuntu-focal/hwe-5.8 Commit-hash: 14e4a095b29fd290a9b80f6e553adcfcf01672d1 + --- + ProblemType: Bug + ApportVersion: 2.20.11-0ubuntu27.16 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC1: test 2903 F.... pulseaudio + /dev/snd/controlC0: test 2903 F.... pulseaudio + CasperMD5CheckResult: skip + CurrentDesktop: Budgie:GNOME + DistroRelease: Ubuntu 20.04 + MachineType: TUXEDO TUXEDO Aura 15 Gen1 + Package: linux (not installed) + ProcFB: 0 amdgpudrmfb + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.8.0-48-generic root=UUID=59a028a1-0764-418a-951d-515f1839bd7f ro ignore_loglevel quiet splash i8042.reset i8042.nomux i8042.nopnp i8042.noloop xhci_hcd.quirks=1073741824 vt.handoff=7 + ProcVersionSignature: Ubuntu 5.8.0-48.54~20.04.1-generic 5.8.18 + RelatedPackageVersions: + linux-restricted-modules-5.8.0-48-generic N/A + linux-backports-modules-5.8.0-48-generic N/A + linux-firmware 1.187.9 + Tags: focal + Uname: Linux 5.8.0-48-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo + _MarkForUpload: True + dmi.bios.date: 11/13/2020 + dmi.bios.release: 7.3 + dmi.bios.vendor: INSYDE Corp. + dmi.bios.version: 1.07.03RTR2 + dmi.board.asset.tag: Tag 12345 + dmi.board.name: AURA1501 + dmi.board.vendor: TUXEDO Computers + dmi.board.version: Not Applicable + dmi.chassis.asset.tag: No Asset Tag + dmi.chassis.type: 10 + dmi.chassis.vendor: Notebook + dmi.chassis.version: N/A + dmi.modalias: dmi:bvnINSYDECorp.:bvr1.07.03RTR2:bd11/13/2020:br7.3:svnTUXEDO:pnTUXEDOAura15Gen1:pvrNotApplicable:rvnTUXEDOComputers:rnAURA1501:rvrNotApplicable:cvnNotebook:ct10:cvrN/A: + dmi.product.family: Not Applicable + dmi.product.name: TUXEDO Aura 15 Gen1 + dmi.product.sku: AURA1501 + dmi.product.version: Not Applicable + dmi.sys.vendor: TUXEDO ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1922754/+attachment/5484797/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1922754 Title: Make AMD gpus choose YCbCr420 encoding automatically when required for 4k 60Hz output To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1922754/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
