Description Steve Cossette 2024-01-28 21:26:22 UTC

I have two computers with Plasma 6 (On Fedora 40 Rawhide), and only the laptop exhibit this issue.

If I open my laptop after a decent amount of time inactive, whatever password I enter in kscreenlocker will always be refused with "Password incorrect". (I did double-check the password a couple times now by clicking the eye icon).

Trying a second time logs me right in.

I can also see this in my system logs, I think it may be relevant:

Jan 28 16:14:58 fedora kscreenlocker_greet[16688]: The cached device pixel ratio value was stale on window expose.  Please file a QTBUG which explains how to reproduce.
Jan 28 16:14:58 fedora kscreenlocker_greet[16688]: qt.qpa.wayland: Could not create EGL surface (EGL error 0x3000)
Jan 28 16:14:59 fedora kscreenlocker_greet[16688]: Failed to write to the pipe: Bad file descriptor.

Is this with a multi-screen setup? If so can you try again with only a single screen and see if it still happens? Thanks!

Nope, single screen.

Thanks. How strange. :/

Comment 5 Steve Cossette 2024-02-16 14:37:16 UTC

After playing with this, this only happens roughly 80-85% of the time for me. Sometimes it works fine.

Comment 6 Nate Graham 2025-05-15 19:47:57 UTC

Hi Steve! Sorry it's been a while and we didn't look into this yet. Are you able to say whether it's still happening in Plasma 6.3.5 or later? Thanks!

Comment 7 Steve Cossette 2025-05-15 20:05:33 UTC

Oh no this hasn't happened in a long time, you can probably close this.
