[plasmashell] [Bug 371455] Slide show wallpaper massively slows down login when many images are configured
https://bugs.kde.org/show_bug.cgi?id=371455 --- Comment #57 from Nate Graham --- I fully agree that Neon should drop the LTS distro base. Neon is itself a franken-distro, which is part of the reason why it unfortunately breaks so much. :( -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=371455 --- Comment #56 from Oded Arbel --- While I agree with the sentiment, Nate, and as such I'm always running the current release - there are valid reasons to use an LTS release without restricting yourself to the version of Plasma that came with the LTS - you might want to make sure that the C compiler is the version from the LTS, with all of the LTS Caves, or the Python interpreter, because you user the system to support production services running on an LTS, but as the production service isn't using a desktop UI - maintaining that compatibility isn't important. BTW - if keeping to a base LTS is just a false promise we can do without, then I would really love to see Neon target the current Ubuntu instead of the LTS - it would make my life a lot easier 😇. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=371455 --- Comment #55 from Nate Graham --- Also JFYI, if you opt to overlay Neon repos on top of your Kubuntu LTS installation, you've already broken the distro's LTS promise by monkeying with it in a way that isn't covered by the LTS support contract. If you're willing to do that, you might as well just use the23.04 release of Kubuntu which is a cohesive product and not a franken-distro. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=371455 --- Comment #54 from Nate Graham --- Oops, actually I meant to recommend Kubuntu 23.04. It's not an LTS release, but it has Plasma 5.27 in it. Personally I don't recommend sticking with LTS releases. In my opinion they represent a false promise. You do get "stability", for certain definitions of stability; the definition that ends up actually being used tends to be "stability of bugginess": It simply has the bugs that it has. The bugs don't change. Sometimes, maybe, some of them might get fixed, but that's not guarantee of that. Mostly you're just stuck with a fixed, unchanging set of bugs. So if you're using an LTS version that has a major bug for you which has already been fixed in a newer version of the software, you're mostly out of luck. I get that LTS distros feel like they fit into the conservative update scheduled of institutional users, but this has to be counterbalanced against the possibility of hitting a bad bug that's already fixed upstream that you don't have access to yet, which is exactly what's happening here. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=371455 --- Comment #53 from Oded Arbel --- Mi(In reply to Nate Graham from comment #52) > in your case, that would be by upgrading the distro to Kubuntu > 34.04. You probably meant Kubuntu 24.04 - the next LTS release that will be made available 9 months from now. Updating from the (still supported, theoretically) 20.04 to the current supported LTS - 22.04, will still not solve this issue as it was apparently fixed for Plasma 5.25 and the fix was never backported to a 5.24 bug fix release - which is what Kubuntu 22.04 is carrying. > If you need support for Plasma 5.18, please contact your distro, who bears > the responsibility of providing support for older releases. Thanks for > understanding! Unfortunately it doesn't look like this issue will ever be addressed in an LTS update - it is likely considered too minor to warrant the backporting effort. Alex, if updating to the non-LTS Kubuntu 23.04 is not an option for you (as I suspect it isn't), then other than backporting the fix yourself, or living with this issue for the next 9 months (plus how ever long it will take to certify your system for a new LTS), and assuming you need a base LTS but can update just Plasma to a more recent version - then I can recommend installing the Neon User Edition focal repository and updating Plasma from there - it features Plasma 5.26 that is compatible with Kubuntu 20.04, and though it is no longer being updated, I expect it to continue to be available for a while (the 18.04 repo - bionic - is still there), and you'd still likely get better experience and support with that than using Plasma from the oldest sill supported Kubuntu LTS... -- You are receiving this mail because: You are watching all bug changes.

This changes so that it's only created when it's needed, which helps to remove some startup disk accesses.

https://bugs.kde.org/show_bug.cgi?id=371455 --- Comment #48 from Oded Arbel --- (In reply to Nate Graham from comment #47) > *** Bug 431256 has been marked as a duplicate of this bug. *** For me the problem isn't actually during login (the login may be slowed by the same issue, but its not very slow and it only happens once) - the problem I have, as documented in the above dup bug report, is that the extraneous directory scanning happens every time I open a plasma shell dialog - even not the wallpaper configuration. This is a video showing the issue: http://test.geek.co.il/plasmashell-stuck-scanning-wallpapers.mp4 - in it you can me opening the system tray configuration dialog and waiting about 4 minutes until it is responsive, while plasma is scanning files and folders. It does not look like a single scan - strace shows plasmashell iterating over the same folders and files multiple times where each file is scanned 8 times. The weird thing is that this behavior seems to be centered around the path ~/.local/share/wallpapers - in my setup this contains a set of symbolic links to specific sub-folders in my wallpaper collection, or it could be a mount to NAS that contains the wallpaper collection, either way - in this setup I observed the behavior shown in the video. If I remove the symbolic links, or the mount, leaving ~/.local/share/wallpapers as an empty folder - then there is no problem: plasma dialogs are snappy and there is no freezing, regardless of how the wallpaper slideshow plugin is configured. -- You are receiving this mail because: You are watching all bug changes.

The patch compiles and does show the last image shown the last time on startup. But it doesn't fix the problem: * The plasmashell process still consumes huge amount of processing time immediately from the login * During that time, many plasma things don't work, including the "Start menu" or whatever KDE calls it, the status bar with the notification icons, etc. Maybe it helps to re-state what the problem is (the fact that the wallpaper doesn't show immediately, which you fixed in the patch, is only one problem). The main problem is that, now, Plasma appears to "scan and read" the whole image collection immediately after log-in (not sure what for), and this freezes the rest of plasma desktop for a considerable while. (More than 10 minutes on this machine... I.e., I don't log out any more, I just lock the screen instead, because logging in to a working system takes ages.) In earlier versions, there was no problem like this. I don't know what changed internally, but the explanation in Comment #13 sounds correct to me. -- You are receiving this mail because: You are watching all bug changes.

In 5.16, a QStringList stores all pictures' paths, but the information of each picture will not be checked before it is displayed.

https://bugs.kde.org/show_bug.cgi?id=371455 --- Comment #27 from Christian --- I have no experience in debugging KDE but started comparing versions and files because this bug is "bugging me". Could it be that this commit introduced the behaviour? It's the only change I could find that seems to be related to the background slideshow. https://github.com/KDE/plasma-workspace/commit/ea32a7611227ca141bd60d983d1489d2be82d10f#diff-821d7994d425d401a2d150dca027d8dc My guess is that replacing the old code: m_timer.stop(); m_slideshowBackgrounds.clear(); m_unseenSlideshowBackgrounds.clear(); BackgroundFinder *finder = new BackgroundFinder(this, m_dirs); m_findToken = finder->token(); connect(finder, &BackgroundFinder::backgroundsFound, this, &Image::backgroundsFound); finder->start(); with the new code: m_timer.stop(); m_slideshowModel->reload(m_slidePaths); connect(m_slideshowModel, &SlideModel::done, this, &Image::backgroundsFound); somehow causes the whole plasma background to wait until all the paths have been scanned. Maybe the purpose of starting the "finder" after connecting it was just this, to avoid the delay? Just a guess. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=371455 --- Comment #25 from Little Jhonnes --- Today there was one more update of kde and I still can not understand how a problem that a few weeks ago did not exist becomes part of the system in this way. After each update I test to see if it has been resolved and kde hangs for a few minutes. I'm even thinking of using variety again to have the same function on the system, at least in part. And thinking that was one of the things that made me true to kde so far. I wish the developers luck.I'm very sad about this. -- You are receiving this mail because: You are watching all bug changes.

My large collection is on a local drive, i.e., the network is definitely not the problem. Probably the same bug behaviour can be seen when opening the Background settings, choosing Slideshow, and then adding a folder with a large number of images (in subfolders). This causes the settings window to freeze for minutes. -- You are receiving this mail because: You are watching all bug changes.

Can anyone > who was originally experiencing this issue still reproduce it in Plasma 5.17? Hi Nate! This issue appears with 5.17 for me :/. No problem with 5.16.5. I switched from frameworks 5.60 to 5.64 at the begging of December (no issue at that moment). I switched from 5.16.5 to 5.17.4 this week.

It was the best description. This occurs both for starting the system after the splash screen and for returning the lock screen login when slideshow with many wallpapers is set up. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=371455 --- Comment #15 from Little Jhonnes --- Hello! A few days ago I noticed a bug that made my kde lock screen crash and only come back a few minutes later, usually 10 to 15 minutes. This occurs when the lock screen is in "slideshow" mode and the folder (or folders) configured with the images has too many images. A similar bug occurs if the desktop is set to "slideshow" and the folder has too many wallpapers. In this case, what happens is that the system takes a long time to leave the presentation screen and go to the desktop. I do not know what the limit of wallpapers seems reasonable to the system, but the absurd amount I have (over 30 thousand) makes the system have this problem. When I used debian and kde was 5.12 I never noticed any of them, so it's probably something in kde 5.17, because even in 5.16, which I remember using in Manjaro, there weren't any of these problems -- You are receiving this mail because: You are watching all bug changes.
