gman <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #3 from gman <[email protected]> --- Hi there, same bug here in Fedora, using kwin Version 6.5.5, Release 1.fc43. Laptop with a integrated amd gpu, a discrete nvidia gpu and an external monitor. Same errors in logs. There _seems_ to be no regressions related to these errors, but still, there must be a reason for the errors to occur. I've found a topic which describes possible reason and a workaround: https://bbs.archlinux.org/viewtopic.php?id=310531 > tell KWin in which order to prefer DRM devices for displays / compositing. I > want Nvidia="card1" to be used preferably. > The goal here is to keep compositor and scan-out on one GPU, or at least a > path the driver likes better: define a systemd user variable: > systemctl --user edit plasma-kwin_wayland.service > [Service] > # Prefer NVIDIA (card1) over Intel (card2) for KWin because of > external-monitor bug > Environment=KWIN_DRM_DEVICES=/dev/dri/card1:/dev/dri/card2 I've tried this workaround and it indeed eliminates the errors. However, I don't want kwin to run primarily on the nvidia gpu, so I decided against it. from inxi: > System: > Kernel: 6.18.5-200.fc43.x86_64 arch: x86_64 bits: 64 compiler: gcc v: 15.2.1 > Desktop: KDE Plasma v: 6.5.5 Distro: Fedora Linux 43 (KDE Plasma Desktop > Edition) > CPU: > Info: 8-core model: AMD Ryzen 7 6800H with Radeon Graphics bits: 64 > type: MT MCP arch: Zen 3+ rev: 1 cache: L1: 512 KiB L2: 4 MiB L3: 16 MiB > Speed (MHz): avg: 1096 min/max: 404/4787 boost: enabled cores: 1: 1096 > 2: 1096 3: 1096 4: 1096 5: 1096 6: 1096 7: 1096 8: 1096 9: 1096 10: 1096 > 11: 1096 12: 1096 13: 1096 14: 1096 15: 1096 16: 1096 bogomips: 102207 > Flags-basic: avx avx2 ht lm nx pae sse sse2 sse3 sse4_1 sse4_2 sse4a ssse3 svm > Graphics: > Device-1: NVIDIA GA104M [Geforce RTX 3070 Ti Laptop GPU] vendor: Lenovo > driver: nvidia v: 580.119.02 arch: Ampere bus-ID: 01:00.0 > Device-2: Advanced Micro Devices [AMD/ATI] Rembrandt [Radeon 680M] > vendor: Lenovo driver: amdgpu v: kernel arch: RDNA-2 bus-ID: 35:00.0 temp: > 40.0 C > Display: wayland server: Xwayland v: 24.1.9 compositor: kwin_wayland > driver: X: loaded: amdgpu,nvidia unloaded: modesetting,nouveau,radeon > dri: radeonsi gpu: amdgpu,nv_platform,nvidia,nvidia-nvswitch resolution: > 1: 2560x1440~60Hz 2: 1920x1080 > API: EGL v: 1.5 drivers: kms_swrast,nvidia,radeonsi,swrast platforms: > active: gbm,wayland,x11,surfaceless,device inactive: device-2 > API: OpenGL v: 4.6.0 compat-v: 4.5 vendor: amd mesa v: 25.2.7 glx-v: 1.4 > direct-render: yes renderer: AMD Radeon 680M (radeonsi rembrandt LLVM > 21.1.5 DRM 3.64 6.18.5-200.fc43.x86_64) > API: Vulkan v: 1.4.328 drivers: radv,nvidia,llvmpipe surfaces: N/A > devices: 3 > Info: Tools: api: clinfo, eglinfo, glxinfo, vulkaninfo > de: kscreen-console,kscreen-doctor gpu: nvidia-settings,nvidia-smi > wl: wayland-info x11: xdriinfo, xdpyinfo, xprop, xrandr -- You are receiving this mail because: You are watching all bug changes.
