Thank you very much for your reply! The only thing I do not understand is why the change, because until two or three days ago everything was working perfectly...
However, this is my /etc/xdg/lxsession/LXDE/autostart: @xscreensaver -no-splash @lxpanel --profile LXDE @pcmanfm --desktop --profile LXDE @/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1 @setxkbmap -option grp:switch,grp:alt_shift_toggle,lv3:ralt_switch,terminate:ctrl_alt_bksp it,de,gr @xcompmgr -r 4.2 @kupfer --no-splash Is it really necessary to add gnome-keyring to autostart? You can not restore the status quo? Thanks again!
