He's not asking for pretty moving pictures, just blanking the screen is fine. the tty can do it just fine tunable in /sys/module/kernel/parameters/consoleblank so this really is a plymouth bug to me, it should have everything it needs for this embedded in the initrd to be able to do that before the OS fully loads. > > My issue is with displaying the same password prompt forever, causing screen burn-in. > > Do you have OLED monitor? Generic LCD/LED monitors does not suffer from > this issue. I never shut down my monitor for years and it works fine. LCD definitely has this issue - display the same image forever and the pixels will remember it / you will be left with an overlay of the previously still image. I'm not sure if the shiniest newest generations of LCD have the problem or not, but I've had multiple generations (latest being 5ish years old) and they all have the issue - for example the top/bottom bars of my window managers are burned in and the rare times I leave it on white-ish background I can still see them, because it's just always there and hardly ever changes. It's unnoticeable most of the time but definitely present, if the luks prompt stays up for a few weeks I'm sure it'll be visible. (It's probably fine overnight, but it can't hurt the electricity bill anyway) -- Dominique _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
