Hi. Some time ago (probably between two weeks and month) after another system update I started encountering problems with some userland services like blueman and nm-applet.
I have encountered blueman problem every time when I logged in to my XFCE session. Right after XFCE init I did see this: https://github.com/blueman-project/blueman/issues/913 Probably at the same time I became unable to enable my VPN connections using nm-applet. After choosing my connection from dropdown menu I've seen the error in notification bubble: > The VPN connection "..." failed to start. > Not authorized to control networking Third but not as likely related (not sure if it started to happen at the same time) is XFCE shutdown/reboot problems. For some time I'm unable to directly shutdown or reboot my PC from XFCE "Action Buttons" panel plugin. If I choose "Restart" or "Shut Down" then XFCE just logs out from my session and I will see SDDM. If I choose shutdown/reboot in SDDM then all will be ok but direct shutdown from XFCE only logs me out. And fourth problem is that for some time I became unable to mount USB flash drives from the file manager. In Thunar when I'm clicking on USB drive nothing happens (even nothing in the thunar console output if I run it from there). There is also nothing strange in journalctl when I'm plugging my USB flash drive. If I try to mount my USB drive using "sudo mount /dev/sdX1 /media/usb_flash" then all works perfectly. udisksctl which I've never used in the past (but was told to try after mentioning this problem) mounts USB drive correctly but only after asking root password. After reading the issue in the blueman repository I tried "fix" which was mentioned here: https://github.com/blueman-project/blueman/issues/912#issuecomment-427648539 https://github.com/blueman-project/blueman/wiki/PolicyKit It did help with blueman error on XFCE start. I'm not familiar with policykit at all but it looks like there was some systematic changes in permission policies and I think that there must be more correct and more generic solution than manually creating policykit policies for every service which I notice problems with. -- Kind regards, Alexey Eschenko https://skobk.in/
