Does anyone have a fix for this problem?

  1. Try to print a pdf (multiple printers tried from two different computers - Xerox, Brother & HP, multiple documents)

  2. Parts of printed page are blank

I have also tried printing them directly from Firefox, as well as from Document Viewer, but it doesn't make any difference.

Same document prints fine when printing from Windows or a MAC to the same printers.

I'm using a Dell XPS-13-9360 laptop (no external drivers needed or detected, according to Ubuntu), connected to a TV through a Thunderbolt to HDMI adapter. I'm getting sound through the HDMI cable, but the TV still says no input. I've tried Wayland and Xorg, and when I open Screen Display settings, the TV is detected, but nothing shows up on it, whether I try to join the displays, mirror them or set it to ONLY TV. I've tried rebooting, too, but no go. What can I do to get this working?

Thanks in advance for any help, Les.

After fresh installs of Ubuntu 18.04 and nmap (snap install) on two separate machines, both return the same nmap error:

dnet: Failed to open device [device-name] QUITTING!

when I run the command:

sudo nmap -sn 192.168.1.0/24

Is there a new syntax I should be using?

The command works without sudo, but outputs less information.

Nmap version is 7.25SVN
