I compiled and installed KDE 5 (Frameworks 5.28.0 and Plasma 5.8.4) from scratch succesfuly, but after the SDDM login, there's only a black screen with a cursor. If I start xterm from the console, it appears. What's interesting is that I can start fine KDE 4 from the SDDM (only KDE 5 shows this problem, so my conclusion is that the X and graphics setup are fine). I tried to run plasmashell from the console and nothing happens: Here's the log: Failed to connect to bus: No such file or directory Loading stage "initial" 587 startkde: Starting up... kdeinit5: preparing to launch '/usr/local/kde5/lib/libexec/kf5/klauncher' kdeinit5: Launched KLauncher, pid = 797, result = 0 Connecting to deprecated signal QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString) kdeinit5: opened connection to :0.0 kdeinit5: preparing to launch 'libkdeinit5_kded5' kdeinit5: Launched KDED, pid = 801 result = 0 kdeinit5: preparing to launch 'libkdeinit5_kcminit_startup' kdeinit5: Launched 'kcminit_startup', pid = 802 result = 0 kdeinit5: Got SETENV 'KDE_MULTIHEAD=false' from launcher. kf5.kded: No X-KDE-DBus-ServiceName found in "/usr/local/kde5/lib/plugins/kf5/kded/solidautoeject.so" kf5.kded: No X-KDE-DBus-ServiceName found in "/usr/local/kde5/lib/plugins/kf5/kded/freespacenotifier.so" kf5.kded: No X-KDE-DBus-ServiceName found in "/usr/local/kde5/lib/plugins/kf5/kded/bluedevil.so" kf5.kded: No X-KDE-DBus-ServiceName found in "/usr/local/kde5/lib/plugins/kf5/kded/ksysguard.so" kf5.kded: No X-KDE-DBus-ServiceName found in "/usr/local/kde5/lib/plugins/kf5/kded/baloosearchmodule.so" kf5.kded: No X-KDE-DBus-ServiceName found in "/usr/local/kde5/lib/plugins/kf5/kded/proxyscout.so" kf5.kded: No X-KDE-DBus-ServiceName found in "/usr/local/kde5/lib/plugins/kf5/kded/remotedirnotify.so" kf5.kded: No X-KDE-DBus-ServiceName found in "/usr/local/kde5/lib/plugins/kf5/kded/desktopnotifier.so" kf5.kded: No X-KDE-DBus-ServiceName found in "/usr/local/kde5/lib/plugins/kf5/kded/ktimezoned.so" kf5.kded: No X-KDE-DBus-ServiceName found in "/usr/local/kde5/lib/plugins/kf5/kded/device_automounter.so" kf5.kded: No X-KDE-DBus-ServiceName found in "/usr/local/kde5/lib/plugins/kf5/kded/keyboard.so" kf5.kded: No X-KDE-DBus-ServiceName found in "/usr/local/kde5/lib/plugins/kf5/kded/statusnotifierwatcher.so" kf5.kded: No X-KDE-DBus-ServiceName found in "/usr/local/kde5/lib/plugins/kf5/kded/soliduiserver.so" kf5.kded: No X-KDE-DBus-ServiceName found in "/usr/local/kde5/lib/plugins/kf5/kded/kscreen.so" kf5.kded: No X-KDE-DBus-ServiceName found in "/usr/local/kde5/lib/plugins/kf5/kded/networkstatus.so" Initializing "kcm_access" : "kcminit_access" kdeinit5: Got EXEC_NEW '/usr/local/kde/bin/kaccess' from launcher. kdeinit5: preparing to launch '/usr/local/kde/bin/kaccess' Initializing "kcm_style" : "kcminit_style" kdeinit5: Got EXEC_NEW '/usr/local/kde5/lib/libexec/kf5/kconf_update' from launcher. kdeinit5: preparing to launch '/usr/local/kde5/lib/libexec/kf5/kconf_update' kf5.kcoreaddons.kaboutdata: Could not initialize the equivalent properties of Q*Application: no instance (yet) existing. kdeinit5: PID 814 terminated.
