inotify max_user_watches

I have found that when using applications like clementine that uses inotify setting it to 10 000 does not help, it needs to be set to 1048576 when the library is 100 000+. This is the only part in the wiki that mentions this value. So I think we need to add a mention here for large collections or have a page that explains inotify a little more.

Magic Trick (~/.compose-cache) - does it still work?

It seems information of ~/.compose-cache has been lost?

After a bit of testing, it still seems to work just fine:

ls -lh ~/.compose-cache

Is there any upstream link for this trick? We need to show user this low level trick is actually useful. -- Fengchao (talk) 08:42, 22 November 2019 (UTC)Reply[reply]
No upstream link, but I'm using the following as reference:

qt5ct and kvantum bugs after upgrade

This is personal experience though. The true cause are still unknown, but im sure it happens to other user as well especially they who update this when new KDE hidpi option introduced. Dikasetyaprayogi (talk) 01:14, 26 March 2021 (UTC)Reply[reply]

Is there any point in this section now? I remember something like this did happen but I didn't solve it in any of the ways suggested here. (I believe I changed my xorg config.) I don't have kvantum installed and I'm pretty sure I never did. I'm not sure what kt5ct is/was, but it isn't in pacman's repositories now and it doesn't seem to be in AUR either. --cfr (talk) 16:45, 21 August 2022 (UTC)Reply[reply]

Nvidia GBM support for version 5.23.2

It seems there will be support for GBM coming with KDE version 5.23.2 and the upcoming Nvidia driver: https://www.phoronix.com/scan.php?page=news_item&px=KDE-Plasma-GBM-NVIDIA-Ready

The merge request mentions that GBM will be used as standard, but users can still force EGLstreams with:

 KWIN_DRM_FORCE_EGL_STREAMS=1

I guess that egl-wayland will also not be necessary anymore.

CLI control

It would be useful to have information about controlling KDE from the command line e.g. kwin. This information is hard to find (or I'm bad at finding it) and often useful. For example

qdbus org.kde.KWin /Compositor suspend
qdbus org.kde.KWin /Compositor resume

In those particular instances, those are just D-Bus interfaces. Perhaps we could elaborate on generalized D-Bus usage on that page, and list some of KDE's D-Bus interfaces here (w/ a source code citation). - CodingKoopa (talk) 00:35, 30 September 2022 (UTC)Reply[reply]
I created Special:PermanentLink/772926#Tips for finding and using D-Bus interfaces to give this some more visibility. -- CodingKoopa (talk) 17:12, 16 March 2023 (UTC)Reply[reply]

Suggested window decoration related tip/trick

If you add an application menu window decoration, you lose the standard application menu from all affected applications. Removing the decoration does not restore the regular menu. Nor does ctrl+m get it back. Instead, you need to change

 MenuBar=Disabled

to

 MenuBar=Enabled

in all ~/.config/applicationrc configuration files and then start the application(s) afresh. --cfr (talk) 18:54, 8 December 2022 (UTC)Reply[reply]
