"unity" starts again successfully. Unfortunately, I do not why. What I did: I noticed that in "~/.cache.upstart.unity7.log" I saw compizconfig - Info: Backend : gsettings compizconfig - Info: Integration : true compizconfig - Info: Profile : unity-lowgfx
The "unity-lowgfx" surprized me. Thus, I replaced the "set -e" in "/usr/lib/i386-linux-gnu/unity/compiz-profile-selector" by "set -evx". This resulted in "unity7.log" in: ... /usr/lib/i386-linux-gnu/unity/compiz-config-profile-setter $settings_profile + /usr/lib/i386-linux-gnu/unity/compiz-config-profile-setter unity compizconfig - Info: Backend : gsettings compizconfig - Info: Integration : true compizconfig - Info: Profile : unity-lowgfx (process:9252): GLib-GIO-WARNING **: g_settings_set_value: value for key 'visual-bell-type' in schema 'org.gnome.desktop.wm.preferences' is outside of valid range Switched to profile 'unity' (for environment 'ubuntu') compizconfig - Info: Backend : gsettings compizconfig - Info: Integration : true compizconfig - Info: Profile : unity /usr/lib/i386-linux-gnu/unity/compiz-profile-selector: Zeile 48: 9252 Speicherzugriffsfehler (Speicherabzug geschrieben) /usr/lib/i386-linux-gnu/unity/compiz-config-profile-setter $settings_profile This means, that for some reason I have previously used the "unity- lowgfx" profile. I forced "settings_profile=unity" in "/usr/lib/i386 -linux-gnu/unity/compiz-profile-selector", restarted the user session and "unity" was back again. It also started much faster than ever in the past. Apparently, part of my "DCONF" configuration has been reset (magically): the "unity" (and launcher) have now their default values. I will see soon what happens, when I restore the previous DCONF configuration. I had also removed some no longer functioning "autostart" configurations and removed some broken "evolution" sources. I do not suppose that this was important. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1756585 Title: unity session without window decorations, panel and launcher To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1756585/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
