Screen curtain is unnatural and unnecessary on desktop: please provide option to disable
[Please accept my apologies if this isn't a gdm issue: the discussions I've seen of it claim it is solved by removing gdm, so..]
Please provide an option to disable the "screen curtain": it is an unnecessary and counterintuitive "innovation" for desktop users.
In gdm 3.30.2-3 (Debian buster), the lock screen takes the form of a mobile phone "curtain", which needs to be swiped away. This is completely unnatural for a desktop computer with a mouse, and requires users to perform an unnecessary additional action where their intent is already both clear and clearly understood by the desktop environment. Why require a complicated multi-finger gesture when only one response to user activity — showing a password dialog/revealing the desktop — is available?
Anyone used to "traditional" lock screens, where you just move the mouse to get a login prompt, is instead confronted by a mystifying swipe animation when they nudge the mouse prior to login. The interface clearly understands the user's intent yet is insisting on a completely unnecessary new action rather than reacting as expected.
Even on laptop this action would appear superfluous and excessive compared to the previously-usual tap on the touchpad.
Desktop users rarely keep their mouse, keyboard and monitor in their pocket, so, on desktop, interaction with one of these three is in almost all cases volitional and can only be intended to reveal the login dialog.
This interaction makes no sense anywhere except on a touchscreen device: simply nudging the mouse is adequate to convey user intent and should result in the traditionally expected behaviour, not a finger-wagging instruction to jump through further hoops.
