The problem was an old kde-dolphin.desktop file in .local rendering many things unusable. This error is not lancelots fault, I'll continue this on some upgrade bug instead.
the error was found in .xsession-errors and looked like this: deinit4: preparing to launch klauncher(18073) KConfigGroup::readXdgListEntry: List entry MimeType in "/home/robert/.local/share/applications/kde-dolphin.desktop" is not compliant with XDG standard (missingtrailing semicolon). klauncher(18073) KRunMX1::expandEscapedMacro: -miniicon isn't supported anymore (service "Dolphin" ) kdeinit4: preparing to launch /usr/lib/kde4/libexec/kioexec kioexec(20400) KIOExec::KIOExec: command= "dolphin -icon dolphin -caption "Dolphin"" kdeinit4: preparing to launch kioexec(20400) KIOExec::KIOExec: Copying "remote:/" to KUrl("file:///var/tmp/kdecache-robert/krun/20400.0.") kioexec(20400) main: Constructor returned... kdeinit4: preparing to launch kwin: X Error (error: <unknown>[DAMAGE+0], request: XDamageDestroy[DAMAGE+2], resource: 0x1403005) Removing .local and logging in again fixed my problem, close issue. -- network folders not working https://bugs.launchpad.net/bugs/263753 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
