KDE Plasma 6 is coming out today. How/when do we update?

Support KDE Plasma
,
76

I tested Plasma 6 Wayland on my other device and fixed some issues manually.

  • A white cursor is invisible because its official “Breeze_Snow” cursor theme was removed by Plasma 6. No, but it has been changed to the new name “Breeze_Light”.
    :white_check_mark: [Fixed] You can reset a selected official cursor theme in KDE Setting.

  • GTK cursor does not take this QT6 cursor design
    :white_check_mark: [Fixed] For example I want the theme Breeze_Light:

$ gsettings set org.gnome.desktop.interface cursor-theme Breeze_Light

  • GTK cursor size does not respect HiDPI scaling (display resolution: 2880 x 1800, scaling: 150%) when touching some GTK apps.
    :white_check_mark: [Fixed] Move two folders ~/.config/gtk-3.0 and ~/.config/gtk-4.0 including wrong configs to backup

  • Some Electron apps don’t respect QT6 Wayland HiDPI scaling
    :white_check_mark: [Fixed] When using version 27 of electron, edit ~/.config/electron27-flags.conf to add:

--enable-features=WaylandWindowDecorations
--ozone-platform-hint=auto
  • Some appimages, for example Joplin, do not respect HiDPI scaling again.
    :white_check_mark: [Fixed] Edit ~/.local/share/applications/appimagekit-joplin.desktop to change
Exec=/$HOME/.joplin/Joplin.AppImage %u

to

Exec=env DESKTOPINTEGRATION=0 APPIMAGELAUNCHER_DISABLE=1 /$HOME/.joplin/Joplin.AppImage %u
  • Some GTK apps in Flatpak do not respect your theme.
    :white_check_mark: [Fixed]

  • All SDDM icons (Login, Shutdown, Reboot) are invisible
    :white_check_mark: [Fixed] Go SDDM setting → Apply Plasma Settings → Reset to Default Settings

  • Konsole breaks nerd-fonts-symbols, but other terminals have no issue.
    The known issue: 478549 – Nerd fonts are not rendered on plasma 6 when using detached font
    :white_check_mark: [Trick] : Install some nerds-fonts packages for example: ttf-hack-nerd, then make Hack Nerd Font" as default font in your profile of Konsole

  • Some icons are missing in the KDE pane
    :white_check_mark: [Fixed] Use default icons “Breeze” instead of custom icons

  • QT5 apps for example octopi does not respect QT6 theme.
    :white_check_mark: [Fixed] [Unstable Update] March 2024 Edition - #84 by medmedin

  • I use dual monitors, but the display setting only shows one monitor (Maybe bug)
    :white_check_mark: [Fixed] Go Display setting → Set Replica to “None” then change any resolution to fix this issue.

  • The SDDM screen does not scale by a factor 1,5 and does not follow KDE display setting
    :white_check_mark: [Fixed] You need to manually edit /etc/sddm.conf.d/kde_settings.conf to add

[General]
GreeterEnvironment=QT_SCREEN_SCALE_FACTORS=1.5
  • SDDM’s cursor does not respect the SDDM setting /etc/sddm.conf.d/kde_settings.conf with CursorTheme=Breeze_Light
    :white_check_mark: [Fixed] Edit /usr/share/icons/default/index.theme to change your cursor theme
[Icon Theme]
Inherits=Breeze_Light

If you want to change the cursor size for SDDM, edit /etc/sddm.conf.d/kde_settings.conf

[Theme]
Current=breeze
CursorTheme=Breeze_Light
CursorSize=24

Everything else is fine.

PS: I noticed that some bugs of Plasma 5 have been fixed by Plasma 6 :+1:
