Currently I work with 20.04 LTS and kernel 5.15.0-56-lowlatency. It reports into dmesg: Goodix-TS i2c-GDIX1002:00: acpi_dev_get_resources returned: 1, ts->gpio_count: 2, ts->gpio_int_idx: -1 Goodix-TS i2c-GDIX1002:00: i2c test failed attempt 1: -121 Goodix-TS i2c-GDIX1002:00: i2c test failed attempt 2: -121 After reviewing driver's source code I found that such parameters are very close to code path which is used for bay trail, but my system is not bay trail. When I comment out check for bay trail driver started to work: 776c776 < } else if (/*is_byt() &&*/ ts->gpio_count == 2 && ts->gpio_int_idx == -1) { --- > } else if (is_byt() && ts->gpio_count == 2 && ts->gpio_int_idx == -1) { Maybe this is not correct fix and I may fix something in my system so it will start to work with 'normal' driver? Or maybe driver need to be modified as that checking for bay trail is not needed? Thanks. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.25 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/pcmC1D0p: kioskset 4197 F...m alsa_dmixd /dev/snd/controlC0: kioskset 4197 F.... alsa_dmixd /dev/snd/timer: kioskset 4197 f.... alsa_dmixd CasperMD5CheckResult: skip DistroRelease: Ubuntu 20.04 MachineType: Default string Default string Package: linux (not installed) ProcEnviron: SHELL=/bin/bash LANG=en_US.UTF-8 TERM=xterm XDG_RUNTIME_DIR=<set> PATH=(custom, no user) ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/appliance-vmlinuz root=UUID=bfe1498f-1f0d-48fe-b456-bfeebe528053 ro quiet splash nvidia-drm.modeset=1 net.ifnames=0 brd.rd_nr=0 usbcore.autosuspend=-1 elevator=noop vt.handoff=7 ProcVersionSignature: Ubuntu 5.15.0-56.62~20.04.1-lowlatency 5.15.64 RelatedPackageVersions: linux-restricted-modules-5.15.0-56-lowlatency N/A linux-backports-modules-5.15.0-56-lowlatency N/A linux-firmware 1.187.33 RfKill: Error: [Errno 2] No such file or directory: 'rfkill' Tags: focal Uname: Linux 5.15.0-56-lowlatency x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: N/A _MarkForUpload: True dmi.bios.date: 09/26/2019 dmi.bios.release: 5.11 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: S101UJSR200_8GB_R02 dmi.board.asset.tag: Default string dmi.board.name: Default string dmi.board.vendor: Default string dmi.board.version: Default string dmi.chassis.asset.tag: Default string dmi.chassis.type: 10 dmi.chassis.vendor: Default string dmi.chassis.version: Default string dmi.ec.firmware.release: 1.13 dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvrS101UJSR200_8GB_R02:bd09/26/2019:br5.11:efr1.13:svnDefaultstring:pnDefaultstring:pvrDefaultstring:rvnDefaultstring:rnDefaultstring:rvrDefaultstring:cvnDefaultstring:ct10:cvrDefaultstring:skuDefaultstring: dmi.product.family: Tablet dmi.product.name: Default string dmi.product.sku: Default string dmi.product.version: Default string dmi.sys.vendor: Default string To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2002353/+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
