I'm trying to connect my network card in my laptop with my desktop. The
laptop has 18.04 and the desktop has Win 7. I want to use the Ubuntu
18.04 laptop to control the Win 7 desktop. This will be done via cat6
cable, network card to network card. How to set this up? Also, prefer
if a control program is needed that it is free. Thank you.

Do I understand this situation's connectivity to be that there is NO
router? That these two devices do NOT connect to the internet via a
router or similar device such as a gateway device? And, neither device
has more than one network card? Or what?

Most people w/ two devices want both devices to be able to connect to
the internet and many also want the devices to be able to connect to
each other. This is established via such as a router as the 'center' of
a LAN, local area network.

In that scenario, both of the devices connect to the router and the
router connects to the internet and facilitates the devices connecting
to each other.

You have two choices.

1) buy a cheap switch and use regular network cables.
2) get a crossover network cable to connect the devices.

Without a router or DHCP server, you will need to manually assign IP
addresses to the machines. For IPv4 connectivity, use a reserved
network, usually 192.168.1.0/255

I'm not familiar enough with IPv6 to discuss how to set up the
networking stacks in the absence of a DHCP server.

One device can connect to the Internet (the laptop) and it is done
through a cat5 cable to the router.

The Win 7 desktop, which I want to control from the Ubuntu laptop, only
has a network card. With the laptop, if I want the Internet, I can just
unplug the cable from the desktop and plug in the cable from the router.

So, to be clear, just a cat5 cable from laptop network card to desktop
card and then control the desktop from the laptop. The Win 7 desktop
never needs Internet access.

I seemed to get a connection from the laptop earlier, but that's it. I
don't seem able to access the Win desktop so far.

I believe a lot of network cards / ports can "auto sense" the gender of
the connection, so it's possible that a crossover cable may not be needed.

Yes, connection shows up on laptop when cable is plugged in to both
network cards, but not sure of the next step. I see "windows" shown
under network connections, but when I click on it nothing happens.

You need to give each network connection an IP address - e.g
192.168.99.100 and .200 mask 255.255.255.0
Windows: set in Control Panel\Network and Internet\Network Connections
Ubuntu: set in Network Manager

OK, once the laptop and the desktop are connected to the router
1) Can they both, individially, connect to the Internet (I would say "If not then Google how to do that", but if you've
got no internet you need someone to help you, preferably on-site)
2) Once both are internet-enabled, find their respective IP addresses
3) Easiest: set up a Telnet server on the desktop, and a Telnet client on the laptop to control the desktop from a
terminal session on the laptop, or vice versa for the other way round, N.B. This is not entirely secure!
4) Once the basic setup works, back to Google "How to show Windows desktop on Linux"

P.S. Does the laptop have WiFi ability? Most have, but using would require setting up the router proporly.

If there is a router, it can solve what you want to do; because a router
typically is an integrated gateway and switch. Topologically, both the
laptop and desktop can ethernet connect to the router. Occasionally
someone has a gateway device which only has a single ethernet port and
uses wifi for other connxns. If that is the case, I would add an
ethernet switch, which is very economical.

If it were me, I would set this up topologically in a 'conventional'
manner with both devices connected to the router. In that
configuration, you can use it 'unconventionally' if you don't want one
or either of them connected to the internet. That is, either/both can
connect to the internet or not, either/both can connect to each other or
not.

I would still connect the desktop to the router as the 'route' for the
laptop-desktop connection.

That is a common problem; see some of those other msg/s about IP.

....and nobody asked 'what do you mean by control the Win7 desktop'?

Through a 'remote desktop' scenario? Win7 Home does not accept MS 'Remote
Desktop' connections. Ubuntu does have a 'remote desktop' client that can connect to
Windows computers.

There's also 'TeamViewer' (TV), which you would start a TV session on the Windows PC
and then log onto that Windows PC session from the TV client on the Ubuntu box.
