Error messages

There are several error messages in the log files that are puzzling me. When i see an error message i expect something to be broken or not working correctly and i want to report that upstream. I'm looking for some feedback in order to make sure the problem isn't me and any info on these observations.

Running the following as root:

journalctl -b -p err

...gives this output

Error 1: No caching mode page
This doesn't look like an error to me this should be a warning? From what i have understood usb drives don't have to have this.

Error 2: gdm-launch-environment
Seems to be a sanity check in gdm that's failing but i'm rather clueless about this one.

Error 3: ntpd
ntpd is trying to sync before the network has been brought up. The networkmanager-dispatcher-ntpd package is recommended against in the ntp page on the wiki. If that is still the case then this is probably a ntpd setting i've not set correctly, or a missing feature in ntpd.

Error 4: pulseaudio bluez
This looks like a non-critical pulseaudio bug. It should probably check if a bluetooth manager is available before trying to get a list of bluetooth devices.

Error 5: gnome-session
Looks like another sanity check, not sure what's going on here.

Error 6: pulse is allready running
Seems like gnome isn't checking whether pulseaudio is running or not before starting it. It should probably call "pulseaudio --check" before starting it.

Kinda longwinded so i'll repeat what i'm looking for. Sanity check that these are actual upstream bugs and info on where to report them.

Re: Error messages

All the non gdm/gnome ones are totally normal.  The gdm/gnomes one I simply have no idea, because I don't use either.  You're doing pretty well though, as I have a couple errors in my logs that I just totally can't figure out.

Re: Error messages

I can solve number four pulseaudio and bluetooth

Pulseaudio simply tries to use bluetooth, even when there is not bluetooth-hardware. This is itself not an error-message, just an information. I my point of view this message should be more concise and tell the user, that this is not an error or a problem. The maintainer has told me, that I should ignore this message.

Take a look at comments and history:
https://bugs.archlinux.org/task/33646
https://bugs.archlinux.org/task/32427


Solution: Ignore message or install bluetooth.
https://wiki.archlinux.org/index.php/Bluetooth

Notes:
On my laptop this message wasn't never printed, because it has some bluetooth hardware and therefore bluetooth.service is available. On my desktop I've choosen solution two and installed bluez, I prefer clean logs.

Re: Error messages

Error 2: gdm-launch-environment // here to
Error 5: gnome-session // here to
Error 6: pulse is allready running // here to

Upstream (here GNOME and Pulseaudio) shoud take a look a the issues behind them, especially because the look like false positives. If they are false positives they are not just scary, but also misleading during investigation of other issues.
