I not use Wayland because it is still not fully supported by my KDE desktop. The message here reflect some incompatibility with Qt5. Can you try to start CdC using the following: QT_QPA_PLATFORM=xcb skychart |

Hi Patrick, the output I get from running your command is as below: $ QT_QPA_PLATFORM=xcb skychart qt.qpa.qgnomeplatform.theme: The desktop style for QtQuick Controls 2 applications is not available on the system (qqc2-desktop-style).

This last message is an issue with the Gnome theme for Qt5. But out of this message do the application run normally? |

Is this package installed? https://src.fedoraproject.org/rpms/qqc2-desktop-style |

I cannot see it having any effect on CDC's operation, it was more just to let you know it was happening. I only noticed it when running skychart in Terminal to address Request 2704 I have not installed qqc2-desktop-style because it is a KDE-specific library. It relies on KDE Frameworks 5 (kf5). The full list of dependencies needed to use qqc2-desktop-style is: ================================================================================ Package Arch Version Repository Size ================================================================================ Installing: qqc2-desktop-style x86_64 5.111.0-1.fc38 updates 136 k Installing dependencies: kf5-karchive x86_64 5.111.0-1.fc38 updates 162 k kf5-kauth x86_64 5.111.0-1.fc38 updates 152 k kf5-kcodecs x86_64 5.111.0-1.fc38 updates 202 k kf5-kconfigwidgets x86_64 5.111.0-1.fc38 updates 480 k kf5-kguiaddons x86_64 5.111.0-1.fc38 updates 127 k kf5-kiconthemes x86_64 5.111.0-1.fc38 updates 197 k kf5-kirigami2 x86_64 5.111.0-1.fc38 updates 484 k kf5-kwidgetsaddons x86_64 5.111.0-1.fc38 updates 1.6 M plasma-breeze-common noarch 5.27.9-1.fc38 updates 70 M polkit-qt5-1 x86_64 0.114.0-6.fc38 fedora 83 k |

I have installed qqc2-desktop-style and its dependencies as a test. The Wayland message still displays in the output but I think the warning/error is having no impact on CDC. $ skychart QSocketNotifier: Can only be used with threads started with QThread 2024-01-15T22:07:50.673 Start trace 2024-01-15T22:07:50.673 Program version : 4.3-4646-2c30ce9a 2024-01-15T22:07:50.673 Program compiled: 2023/12/11 04:00:43 2024-01-15T22:07:50.673 Compiler version: Lazarus 2.2.4.0 Free Pascal 3.2.2 Linux-x86_64-qt5 2024-01-15T22:07:50.821 Screen scaling : True 2024-01-15T22:07:50.821 Screen scale : 105% 2024-01-15T22:07:50.822 Try language: en 2024-01-15T22:07:50.827 Language: en qt.qpa.wayland: Wayland does not support QWindow::requestActivate() qt.qpa.wayland: Wayland does not support QWindow::requestActivate() qt.qpa.wayland: Wayland does not support QWindow::requestActivate() 2024-01-15T22:07:51.129 Connected to the SQL database /home/<user_name>/.skychart/database/cdc.db 2024-01-15T22:07:51.129 Running on Qt version: 5.15.11 2024-01-15T22:07:51.218 Listen on port: 3292 qt.qpa.wayland: Wayland does not support QWindow::requestActivate() qt.qpa.wayland: Wayland does not support QWindow::requestActivate() qt.qpa.wayland: Wayland does not support QWindow::requestActivate() |

I get a slightly different warning message on the operational telescope system (Ubuntu). I think this might give a clue as how to fix it. "Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway" |
