The problem was caused by an old (created under Ubuntu 12.04) DCONF configuration (attached).
Apparently, there is code to reset such outdated configuration. In my case, however, "/usr/lib/i386-linux-gnu/unity/compiz-config-profile- setter" (usually) crashed (sometimes a SIGSEGV; sometimes the inability to find interface type 3) (for reasons not yet understood) and that code was not reached. Workaround for this problem: copy over "~/.config/dconf/user" (i.e. the DCONF configuration) from a newly created user to the old user with this problem. To be able to restore relevant configuration after the copying, you can save the old configuration with "dconf dump / > user-old.dump" in a readable form before the copying; after the copying "dconf dump / > user-new.dump" will give the new configuration in readable form which can be "diff"ed to the old configuration. "dconf set ..." can be used to restore relevant parts of the old configuration to the new one. ** Attachment added: "old DCONF configuration which caused my problem" https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1756585/+attachment/5085655/+files/dconf-old.user -- 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
