--- Comment #41 from Michael <[email protected]> --- I've added attachments. I'm another user with what sounds like the same issue. It's very repeatable, it happens every single time. I'm running Ubuntu latest stable version, I believe 20.04, and installed Plasma onto it through one of their software tools (not a downloaded file or anything). I subsequently added some eye candy - themes and so on - but again, all through the official screens. I'm aware of the bug where shutdown doesn't work and you have to use a separate desktop shortcut for it, and this isn't that one. Start Ubuntu. Select Plasma at login. System appears to start normally, though event log entries may be pointing at irregularities. From previous experience with various linux versions in the past, there often seems to be some niggle somewhere that doesn't obviously flag up to the user and that they only know about if they read dmesg or a log. Anyway, system appears to behave normally, no apparent problems. Hold down Windows key and press L. Screen locks. The selected image appears on the screen, just the image, nothing else. No password box, no text, no unlock button, nothing. Just the image and nothing else. I did see a reference elsewhere to a bug where there was a very long pause at this point (35 seconds was mentioned), so I waited for two minutes to see if anything else would appear but nothing did. Referring to the log file, screen was locked at 11:20. Unlocking attempts commenced at 11:22. I tried clicking the mouse, double clicking it, swiping it up, swiping it down, dragging upwards, dragging downwards, clicking all four corners of the screen, pressing the ESC key, pressing every letter key in turn, pressing ALT and every letter key in turn, pressing CTRL and every letter key in turn, pressing the Windows key and every letter key in turn. Nothing worked. There was no password box to enter a password into. The only way out was to do a hard shutdown (hold down the power key until it powered off). I did wonder whether this was an Ubuntu bug or a Plasma bug, so I tested it using LXDE which also has a screenlock (icon at the bottom right). I clicked in LXDE and it locked. However, there a password box appeared on the screen. I entered my password and it unlocked again, no problem. I concluded that this couldn't be intrinsic to Ubuntu. It does look as if it's specifically Plasma. Not sure if any of this helps. Please advise if you want it logged separately - I've assumed not as it does appear to be the same issue. >From info centre: KDE Plasma Version: 5.18.5 KDE Frameworks Version: 5.68.0 Qt Version: 5.12.8 Kernel version: 5.4.0-74-generic OS Type: 64 bit Processors: 2 x AMD-C-50 Processor Memory: 3.5 GiB of RAM I can get you further information from the info centre if you ask for it, including graphical information... but there's a lot of it and it doesn't appear possible to export it or copy and paste it. -- You are receiving this mail because: You are watching all bug changes.
