[kwin] [Bug 470063] Graphics driver issues that make shader effects non-functional in KWin session for SDDM lock screen in native Wayland mode
https://bugs.kde.org/show_bug.cgi?id=470063 --- Comment #11 from Daniel Lipovetsky --- Looks like the theme.conf.user originates in the sddm-breeze package: > > dnf repoquery --whatprovides > > /usr/share/sddm/themes/01-breeze-fedora/theme.conf.user > Last metadata expiration check: 0:01:42 ago on Sat 01 Jul 2023 02:10:10 PM > PDT. > sddm-breeze-0:5.27.4.1-2.fc38.noarch > sddm-breeze-0:5.27.6-1.fc38.noarch I renamed the file to theme.conf.original, then ran sddm-greeter: > > sddm-greeter --test-mode --theme /usr/share/sddm/themes/01-breeze-fedora/ > Socket error: "QLocalSocket::connectToServer: Invalid name" > Loading file:///usr/share/sddm/themes/01-breeze-fedora//Main.qml... > kf.kirigami: Failed to find a Kirigami platform plugin > qt.qpa.wayland: Wayland does not support QWindow::requestActivate() > qt.qpa.wayland: Wayland does not support QWindow::requestActivate() > Loading file:///usr/share/sddm/themes/01-breeze-fedora//Main.qml... > QQmlEngine::setContextForObject(): Object already has a QQmlContext > QQmlEngine::setContextForObject(): Object already has a QQmlContext > kf.kirigami: Failed to find a Kirigami platform plugin > qt.qpa.wayland: Wayland does not support QWindow::requestActivate() Note the errors are gone. This resolved the issue for me. I don't know any sddm internals, but perhaps some who does will find this information helpful. Maybe the theme.conf.user file should be removed from the package? For comparison, the breeze theme does not have this file. -- You are receiving this mail because: You are watching all bug changes.
