Hinokami Dev <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #41 from Hinokami Dev <[email protected]> --- ## Summary I am experiencing what appears to be the same KScreenLocker/PAM suspend-resume issue described in this bug. When my system is locked and then suspended, KScreenLocker reports a failed authentication immediately after resume, even though I have not entered my password at all. The lock screen shakes and displays **"Unlocking failed"** automatically. ### Steps to reproduce 1. Lock the system using `Meta+L`. 2. Leave the system locked until it goes to sleep/suspend automatically. 3. Wake the system using the power button on the keyboard. 4. Observe the lock screen before entering any password. ### Observed behavior Immediately after waking: * The lock screen shakes as if an incorrect password was entered. * **"Unlocking failed"** is displayed. * No password has been entered. * After this automatic failure, entering the correct password works normally. I can also reproduce the issue when using the **Sleep** button directly from the lock screen. ### Expected behavior After resuming from suspend, the lock screen should simply wait for my password. It should not report a failed authentication when no authentication attempt was made. ### System information * Fedora Linux 44 * KDE Plasma 6.7.4 * KDE Frameworks: [please add output] * KScreenLocker: `6.7.4-1.fc44` * Qt: [please add output] * Kernel: [please add output] * Graphics platform: Wayland * PAM: `1.7.2-2.fc44` * Architecture: x86_64 ### Additional information This is not simply an incorrect-password issue. The failure occurs automatically immediately after resume, before I enter anything. If I lock the system and unlock it without suspending, the password is accepted normally. The problem is specifically associated with suspend/resume while the system is locked. I found an existing KDE bug discussing very similar behavior, including `PAM_CONV_ERR` and cancellation of the PAM authentication conversation when suspending from the lock screen. The discussion also references MR 340 as a possible fix. I am reporting this because the issue still appears to be reproducible on Fedora 44 with KScreenLocker 6.7.4. -- You are receiving this mail because: You are watching all bug changes.
