Which version of of SDDM (and presumably KDE) are you using?
One of the comments one of those threads you linked points out that the bugs you're sharing are for has changed.
The components have been reworked since the button was disabled so maybe that helped. It used to be a PlasmaComponents2.TextField, now it's a PlasmaExtras.PasswordField.
PlasmaExtras.PasswordField
has the button enabled! However, the implementation in the theme explicitly disables it.
If you open up /usr/share/sddm/themes/breeze/Login.qml
and scroll down to line 106. You'll see rightActions: []
-- this bit of code basically overrides the default behavior. It says "normally you have some actions here, but instead use this list, but [] is an empty list.
So if you just comment that line out by adding //
to the front of it... Everything should just work, since it will then revert back to using the built in value.
However, the reason this was removed in the first place is in a comment on line 105:
// Disable reveal password action because SDDM does not have the breeze icon set loaded
If the icon set fails to load for whatever reason (if youre using a custom icon theme or something, i dunno why it might not be loaded), the button will fail to load again.
You can test drive the SDDM lockscreen by running sddm-greeter-qt6 --test-mode --theme /usr/share/sddm/themes/breeze/
from the terminal.
And this all assumes that you're using the default breeze theme. If you are trying to use a different theme, not sure if any of this applies.
Getting bit by a venomous snake in Australia and you're blood starts to disassemble itself. The only counter is antivenom or die. Your blood breaking down is what kills you. And there is no way to separate the bite from that.
Being able to counter the venom in such a simple way is what makes it different. You can logically break it down into steps that are separable.
