Package: linux-image-amd64 Version: 6.12.90-2 Severity: normal After upgrading from 6.12.88-1 to 6.12.90-2, display mirroring (clone mode) no longer works on GNOME/Wayland. The external display is detected and works in extended mode, but mirroring cannot be activated via GNOME Settings → Displays. Reverting to 6.12.88-1 resolves the issue. Hardware: - Lenovo ThinkPad T14 Gen 5 AMD - AMD Ryzen 7040 series (Phoenix), amdgpu driver - External display via HDMI Software: - Debian 13 (Trixie) - GNOME on Wayland - Kernel 6.12.90+deb13.1-amd64 (broken) - Kernel 6.12.88+deb13-amd64 (working) Relevant dmesg error: ucsi_acpi USBC000:00: ucsi_handle_connector_change: GET_CONNECTOR_STATUS failed (-110)
