The issue does not occur if the password is entered within ~10 seconds of the prompt appearing. This behavior is observed on Ubuntu 25.04 in verbose boot mode. Steps to Reproduce: Connect the Dell Precision 5490 to a Dell SD25TB4 dock with external monitors attached. External screens are sleeping. Power on the laptop and boot into Ubuntu 25.04. Wait for the LUKS password prompt to appear in verbose mode, specifically the line: Begin: Mounting root file system ... Begin: Running /scripts/local-top ... Please unlock disk crypt_dev_nuvme0n1p3: Wait for approximately 30 seconds without typing the password. Enter the password and press Enter. Expected Result: The system should boot successfully and automatically wakeup and detect the external displays, regardless of the time taken to enter the LUKS password. Actual Result: After the 30-second delay, the system boots, but the external displays are not wakenup, not detected or configured and boot continue with only laptop screen. Only way to correct situation is to reboot and type LUKS password faster or un/re-plug cables from dock.
