It's been surprisingly difficult to set up a remote display between two
CentOS boxes, one headless running v.5.9 and the other a new laptop
running v.7.2. Since the one machine is headless, it should be obvious
which is to display the desktop of the other.
The two machines are on the same local network, yet there is iptables
running on both of them. But it's not a big deal for me to add rules
for them. There's already a solid ssh connection from the laptop to the
headless machine.
I recently set up remote display of applications from a Raspian (Debian
running on a Raspberry Pi) to my Android phone-- that took only about an
hour-- and (quite a while ago) an X server displaying apps from another
Linux box-- was also trivial to do-- which is why it's been a mystery
why using gdm is so difficult. Since I've tried a lot of different
settings over the past several days, it would take too long to describe
them all. If perhaps someone could describe the steps from the
beginning, that would be much simpler and would give others seeking the
same on the internet a doc to work from.
So does anyone know how this is done?
