Public bug reported:
I have added a 4K monitor to my desktop for a total of 4 monitors. Without fractional scaling the layout works as expected. The issue is when I scale the new 4K monitor to 125%. The corresponding monitors.xml looks fine. I verified it manually. more details here: https://askubuntu.com/questions/1557725/fix-wrong-fractional- scaling?noredirect=1#comment2741007_1557725 ProblemType: Bug DistroRelease: Ubuntu 24.04 Package: xorg 1:7.7+23ubuntu3 ProcVersionSignature: Ubuntu 6.11.0-29.29~24.04.1-generic 6.11.11 Uname: Linux 6.11.0-29-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia .proc.driver.nvidia.capabilities.fabric-imex-mgmt: DeviceFileMinor: 4323 DeviceFileMode: 256 DeviceFileModify: 1 .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 x86_64 Kernel Module 580.95.05 Tue Sep 23 10:11:16 UTC 2025 GCC version: gcc version 13.3.0 (Ubuntu 13.3.0-6ubuntu2~24.04) ApportVersion: 2.28.1-0ubuntu3.8 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CasperMD5CheckResult: unknown CompositorRunning: None CurrentDesktop: ubuntu:GNOME Date: Fri Oct 24 12:56:22 2025 DistUpgraded: Fresh install DistroCodename: noble DistroVariant: ubuntu DkmsStatus: ipu6-drivers/0~git202406240945.aecec2aa-0ubuntu2~24.04.3, 6.11.0-29-generic, x86_64: installed (Original modules exist) nvidia/580.95.05, 6.11.0-29-generic, x86_64: installed ExtraDebuggingInterest: Yes, if not too technical GraphicsCard: Intel Corporation Raptor Lake-P [Iris Xe Graphics] [8086:a7a0] (rev 04) (prog-if 00 [VGA controller]) Subsystem: Samsung Electronics Co Ltd Raptor Lake-P [Iris Xe Graphics] [144d:c1cc] Subsystem: Samsung Electronics Co Ltd AD106M [GeForce RTX 4070 Max-Q / Mobile] [144d:c1cc] InstallationDate: Installed on 2024-05-06 (536 days ago) InstallationMedia: Ubuntu 24.04 LTS "Noble Numbat" - Release amd64 (20240424) MachineType: SAMSUNG ELECTRONICS CO., LTD. 960XFH ProcEnviron: LANG=en_US.UTF-8 PATH=(custom, no user) SHELL=/bin/bash XDG_RUNTIME_DIR=<set> ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-6.11.0-29-generic root=UUID=79222ea4-1e2b-41f0-bddb-2092351409fc ro quiet splash vt.handoff=7 SourcePackage: xorg Symptom: display UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 04/18/2024 dmi.bios.release: 5.27 dmi.bios.vendor: American Megatrends International, LLC. dmi.bios.version: P07ALQ.190.240418.PS dmi.board.asset.tag: No Asset Tag dmi.board.name: NP960XFH-XA3SE dmi.board.vendor: SAMSUNG ELECTRONICS CO., LTD. dmi.board.version: SGLB450A1I-C01-G002-S0007+10.0.22621 dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: SAMSUNG ELECTRONICS CO., LTD. dmi.chassis.version: N/A dmi.modalias: dmi:bvnAmericanMegatrendsInternational,LLC.:bvrP07ALQ.190.240418.PS:bd04/18/2024:br5.27:svnSAMSUNGELECTRONICSCO.,LTD.:pn960XFH:pvrP07ALQ:rvnSAMSUNGELECTRONICSCO.,LTD.:rnNP960XFH-XA3SE:rvrSGLB450A1I-C01-G002-S0007+10.0.22621:cvnSAMSUNGELECTRONICSCO.,LTD.:ct10:cvrN/A:skuSCAI-ICPS-A5A5-RPLH-PALQ: dmi.product.family: Galaxy Book3 Ultra dmi.product.name: 960XFH dmi.product.sku: SCAI-ICPS-A5A5-RPLH-PALQ dmi.product.version: P07ALQ dmi.sys.vendor: SAMSUNG ELECTRONICS CO., LTD. version.compiz: compiz N/A version.libdrm2: libdrm2 2.4.122-1~ubuntu0.24.04.1 version.libgl1-mesa-dri: libgl1-mesa-dri 25.0.7-0ubuntu0.24.04.2 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 2:21.1.12-1ubuntu1.4 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev N/A version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:22.0.0-1build1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20210115-1build1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.17-2ubuntu0.1 ** Affects: ubuntu Importance: Undecided Status: New ** Tags: amd64 apport-bug noble resolution ubuntu -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2129752 Title: half screen display when using fractional scaling To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/2129752/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
