--- Comment #8 from [email protected] --- Further update on the workaround: I have verified that a physical hot-plug is not strictly necessary. A software-triggered display reconfiguration achieves the exact same recovery. Executing the following command to temporarily alter the scaling geometry unfreezes the desktop immediately: kscreen-doctor output.DP-1.scale.1.25 && sleep 1 && kscreen-doctor output.DP-1.scale.1 This command toggle forces KWin and the NVIDIA driver to renegotiate the display state, which correctly initializes the NV_CRTC_REGAMMA_DIVISOR and NV_PLANE_DEGAMMA_MULTIPLIER registers to 4294967296 (instead of 0) and resolves the atomic commit failures. -- You are receiving this mail because: You are watching all bug changes.
