Hi MyNameIsCosmo,
tnx for your support…some progress but not 100% done yet:
-
all updates based on “apt-get update” installed
-
HDMI not working - need to work with cli
-
uname -a:
Linux turtle 4.4.0-1000-joule #0+joule21-Ubuntu SMP PREEMPT Thu Mar 16 14:46:45 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux -
following your hint “power saving” → focussing on Ubuntu not Joule I did the following:
sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
→ unix processes will not get stopped/suspended anymore → seems ok !
→ issue: every 30min the network manager gets a request to “sleep” (syslog) → wifi connection goes down
→ can’t restart it automatically (service network-manager restart - nmcli network on - ifup -a)
No clue what causes the request for network manager to sleep…given that it is reproducible it seems a “feature”. Any idea how to tackle it? Seems I didn’t disable all “power saving” options (or what soever causes the nm shutdown…) - can’t find anything on the net that fixed it…
Every hint/comment welcome…
