random.dude <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #20 from random.dude <[email protected]> --- Still reproducible on Fedora 44 with plasma-login-manager 6.7.2 (AMD iGPU, monitor on HDMI). Booting with the monitor powered off, then turning it on: the greeter shows the password field and power buttons, but Enter does nothing and the buttons are unresponsive. Working workaround: force the connector as always-connected with the monitor's EDID, so the greeter never starts headless. Copy /sys/class/drm/<card-connector>/edid to /usr/lib/firmware/edid/monitor-edid.bin, include it in the initramfs, and add kernel args drm.edid_firmware=HDMI-A-1:edid/monitor-edid.bin video=HDMI-A-1:e. With this the greeter works normally even when booting with the display off. The workaround suggests that the issue is related to the greeter starting without any active display and not correctly handling a later DRM hotplug event. When the HDMI connector is forced to be present from boot using drm.edid_firmware and video=HDMI-A-1:e, the greeter behaves normally even if the monitor is powered on only afterwards. This may indicate that the issue lies in Plasma Login Manager's handling of displays that appear after the greeter has already started. -- You are receiving this mail because: You are watching all bug changes.
