yes > Does /var/log/journal/ exist? no, should it? > If it does, try: > > journalctl | grep hid-common which says I should sudo it, and when I do, grep only finds itself in 3 stanza's with wrong syntax on the 2nd invocation: COMMAND=/bin/grep -Rhid-common I'll see if /etc/journal exists but doesn't a root@coyote:etc$ grep -R log= * shows: systemd/journald.conf:#ForwardToSyslog=yes systemd/journald.conf:#MaxLevelSyslog=debug So I'd assume anything would be sent to syslog. And its pretty verbose at times. I did find this in the syslog by scanning backwards in tails output: May 17 22:46:35 coyote kernel: [ 5.491350] hid-generic 0003:050D:0751.0001: unknown main item tag 0x1 May 17 22:46:35 coyote kernel: [ 5.491899] hid-generic 0003:050D:0751.0001: unbalanced collection at end of report description May 17 22:46:35 coyote kernel: [ 5.491964] hid-generic: probe of 0003:050D:0751.0001 failed with error -22 But I haven't found 050D:0751 yet. Ahh, it is my Belkin UPS, and nut appears to be working correctly? It appears modemmanager could be removed: May 17 22:46:43 coyote ModemManager[617]: <info> Couldn't check support for device at '/sys/devices/pci0000:00/0000:00:08.0': not supported by any plugin May 17 22:46:43 coyote ModemManager[617]: <info> Couldn't check support for device at '/sys/devices/pci0000:00/0000:00:09.0': not supported by any plugin Removed.

There is a fax utility from tde, but removing it, removes tde. All of it. And several boatloads of certificates revoked, or untrusted like for FUSE which I use heavily here.
