This laptop has a mux switch to switch between dynamic/hybrid or discrete graphics mode. This laptop has a high resolution with high pixel density than the other displays out there, but I don't know the exact number. Additionally, this laptop can adjust the display refresh rate between 60 and 165 Hz. --- There were 1 problem I encountered in dynamic/hybrid graphics mode: - The widgets shown were too small. Details: The resolution was correct, at 2560x1600, but all widgets shown were too small. I suspected this was due to the laptop screen high pixel density and the widget size calculation didn't make use of physical dimension, but in terms of pixel. I thought installing NVIDIA driver would fix this, but no; this worked in OpenSUSE Leap with KDE Plasma and I think it was because of the inclusion of NVIDIA OpenGL driver. The current workaround was to scale by 200% in "Display Settings", although the login screen isn't affected by the scaling at all. --- There were 3 problems I encountered in discrete graphics mode: - The widgets were are too small, like the hybrid graphics mode issue. - The DE seemed to use wrong screen refresh rate. The refresh rate was fixed at 93 Hz in the "Display Settings". Changing the refresh rate between 60 Hz and 165 Hz by Fn keys didn't update the 93 Hz in the "Display Settings". This didn't happen in the hybrid graphics mode. OpenSUSE Leap with KDE Plasma properly detected 60 and 165 Hz, so I think it may be either GNOME DE or xorg misconfigurations. - Screen brightness was fixed at 100%. Details: Screen brightness could be adjusted by the keyboard Fn keys, but the brightness was fixed at 100%. This didn't happen in the hybrid graphics mode. This is the most annoying problem and have forced me to use the hybrid graphics mode which I don't like. My first thought was either a specific NVIDIA issue or xorg misconfigurations. So I tried adding "acpi_backlight=vendor" and "nvdia.NVreg_RegistryDwords=EnableBrightnessControl=1" to GRUB, but didn't work at all. --- In discrete graphics mode, a quick "sudo journalctl -p3 -b0" showed below: Okt 29 18:48:04 jiazhang-Legion-7-16ACHg6 kernel: ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.PB2], AE_NOT_FOUND (20210730/dswload2-162) Okt 29 18:48:04 jiazhang-Legion-7-16ACHg6 kernel: ACPI Error: AE_NOT_FOUND, During name lookup/catalog (20210730/psobject-220) Okt 29 18:48:04 jiazhang-Legion-7-16ACHg6 kernel: integrity: Problem loading X.509 certificate -65 Okt 29 18:48:04 jiazhang-Legion-7-16ACHg6 kernel: ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.GP17.VGA.LCD._BCM.AFN7], AE_NOT_FOUND (20210730/psargs-330) Okt 29 18:48:04 jiazhang-Legion-7-16ACHg6 kernel: ACPI Error: Aborting method \_SB.PCI0.GP17.VGA.LCD._BCM due to previous error (AE_NOT_FOUND) (20210730/psparse-529) In hybrid graphics mode, "sudo journalctl -p3 -b0" output like above except that there was no: Okt 29 18:48:04 jiazhang-Legion-7-16ACHg6 kernel: ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.GP17.VGA.LCD._BCM.AFN7], AE_NOT_FOUND (20210730/psargs-330) Okt 29 18:48:04 jiazhang-Legion-7-16ACHg6 kernel: ACPI Error: Aborting method \_SB.PCI0.GP17.VGA.LCD._BCM due to previous error (AE_NOT_FOUND) (20210730/psparse-529) ProblemType: Bug DistroRelease: Ubuntu 22.04 Package: xorg 1:7.7+23ubuntu2 ProcVersionSignature: Ubuntu 5.15.0-52.58-generic 5.15.60 Uname: Linux 5.15.0-52-generic x86_64 .proc.driver.nvidia.capabilities.gpu0: Error: path was not a regular file. .proc.driver.nvidia.capabilities.mig: Error: path was not a regular file. .proc.driver.nvidia.gpus.0000.01.00.0: Error: path was not a regular file. .proc.driver.nvidia.registry: Binary: "" .proc.driver.nvidia.suspend: suspend hibernate resume .proc.driver.nvidia.suspend_depth: default modeset uvm .proc.driver.nvidia.version: NVRM version: NVIDIA UNIX Open Kernel Module for x86_64 520.56.06 Release Build (dvs-builder@U16-T12-10-2) Thu Oct 6 21:33:54 UTC 2022 GCC version: gcc version 11.3.0 (Ubuntu 11.3.0-1ubuntu1~22.04) ApportVersion: 2.20.11-0ubuntu82.1 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CasperMD5CheckResult: pass CompositorRunning: None CurrentDesktop: ubuntu:GNOME Date: Sat Oct 29 18:50:17 2022 DistUpgraded: Fresh install DistroCodename: jammy DistroVariant: ubuntu DkmsStatus: nvidia/520.56.06, 5.15.0-52-generic, x86_64: installed ExtraDebuggingInterest: Yes, including running git bisection searches GraphicsCard: NVIDIA Corporation GA106M [GeForce RTX 3060 Mobile / Max-Q] [10de:2560] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Lenovo GA106M [GeForce RTX 3060 Mobile / Max-Q] [17aa:3aa6] InstallationDate: Installed on 2022-10-29 (0 days ago) InstallationMedia: Ubuntu 22.04.1 LTS "Jammy Jellyfish" - Release amd64 (20220809.1) MachineType: LENOVO 82N6 ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.15.0-52-generic root=UUID=755b225e-e7d8-439f-a685-8ab759683ed6 ro quiet splash vt.handoff=7 SourcePackage: xorg Symptom: display UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 06/16/2022 dmi.bios.release: 1.57 dmi.bios.vendor: LENOVO dmi.bios.version: GKCN57WW dmi.board.asset.tag: NO Asset Tag dmi.board.name: LNVNB161216 dmi.board.vendor: LENOVO dmi.board.version: SDK0R32862 WIN dmi.chassis.asset.tag: NO Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Legion 7 16ACHg6 dmi.ec.firmware.release: 1.57 dmi.modalias: dmi:bvnLENOVO:bvrGKCN57WW:bd06/16/2022:br1.57:efr1.57:svnLENOVO:pn82N6:pvrLegion716ACHg6:rvnLENOVO:rnLNVNB161216:rvrSDK0R32862WIN:cvnLENOVO:ct10:cvrLegion716ACHg6:skuLENOVO_MT_82N6_BU_idea_FM_Legion716ACHg6: dmi.product.family: Legion 7 16ACHg6 dmi.product.name: 82N6 dmi.product.sku: LENOVO_MT_82N6_BU_idea_FM_Legion 7 16ACHg6 dmi.product.version: Legion 7 16ACHg6 dmi.sys.vendor: LENOVO nvidia-settings: ERROR: A supplied argument is invalid version.compiz: compiz N/A version.libdrm2: libdrm2 2.4.110-1ubuntu1 version.libgl1-mesa-dri: libgl1-mesa-dri 22.0.5-0ubuntu0.1 version.libgl1-mesa-glx: libgl1-mesa-glx N/A version.nvidia-graphics-drivers: nvidia-graphics-drivers-* N/A version.xserver-xorg-core: xserver-xorg-core 2:21.1.3-2ubuntu2.2 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev N/A version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:19.1.0-2ubuntu1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20210115-1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.17-2build1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-520/+bug/1995173/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
