Hello, experts there
I have a new precision 5820 Tower PC delivered from DELL with Ubuntu 16.04 TLS OS installed two days ago.
I have an issue with this PC while remotely login and DELL support team think it is Ubuntu related.
here is what happens:
After less than two hours of login from reboot, the network connection to the PC is automatically cut off.
I went to the Lab where the PC is, touching keyboard or moving mouse will wake up the screen, on Ubuntu login screen, click on top-right , from network/connection information, shows no IP.
if I then first click “Disconnect” and later “my machine name” from network menu, the network will come back.
I have set
- the “Deep Sleep Control =Disabled” from BIOS /Power Management
- “don’t suspend “ from Ubuntu System Setting /power option
- also followed https://askubuntu.com/questions/452908/how-to-disable-suspend-in-14-04
Create a new file
sudo -H gedit /etc/polkit-1/localauthority/50-local.d/com.ubuntu.disable-suspend.pkla
with the following contents:
[Disable suspend (upower)]
[Disable suspend (logind)]
[Disable suspend when others are logged in (logind)]
This is weird. This PC is required to be able to work remotely.
Have I missed any setting? Do you have any suggestion?
Look forward to hearing from you soon
