How to use multiple monitors

[Chen Liang]

Hello everyone!

I have two monitors, and I wanna use both of them. Since Ubuntu has four workspaces, I want each monitor use different workspace respectively. How could I do? 

Thanks in advance!

I'm not an expert in this, but I do run multiple monitors. I don't
think you can do it with the standard software setup of gnome or KDE.
The monitors are always set up with a particular geometric
relationship that determines how you can drag stuff between monitors,
or even have a window span across monitors. If you do a screen
capture, you get all screens as a single image. This seems to imply
the monitors form a single workspace.

OTOH, xorg has the notion of multiple "screen" targets so I think it's
higher-level software, maybe the workspace switcher or window manager
that determines this. There could be software somewhere that does it
the way you describe.

Ubuntu has as many or as few workspaces as you happen to want. Just
right click on the workspaces and you can change them (or do it in the
settings manager).

Depends on your video driver. With nVidia, you just run the settings
program to select your monitors, configure them and then select running
them as a double-width single monitor (twin view) or as separate
monitors. Piece O cake. Just be sure to save the new configuration, log
out and back in again. Trying to use the desktop monitor config apps
won't do one thing, unless the driver is first set correctly. But, that
is how you do it with nVidia. Ric

It doesn't work like that. (Not on any OS I know that supports virtual
desktops.)

What you get it /n/ virtual instances of your screen layout. So, if
you have 2 physical screens & 4 v-desktops, then you get 4 virtual
instances of your dual-screen desktop: top left pair, top right pair,
bottom left pair, bottom right pair, for instance.

I don't know any way to make each physical monitor reflect a different
v-desktop & I am finding it hard to imagine the UI to it. I reckon it
would be a nightmare to try to use.

Configure your machine for dual head and then just use the
vdesktop-switching same as before. Both screens switch together. This
is simple and it works, believe me!

Read the title: "mockup". It's not real.

Good luck! I had 4 LCDs for a while but it always seemed to be a pain
to get them configured right without crashing the darn system. It's
been a while. I'm not sure if I ever tried saving the xorg conf file
and replacing it when I hosed the xorg. Logic tells me that would
have worked. I just scrapped the multiple monitor idea and threw down
a 42" LCD.

Hmm, after watching the mock-up a little, it _almost_ looks like they
are using one PC for each monitor; and using Synergy for the single
Keyboard/mouse. Except that, as far as I know, Synergy doesn't allow
moving a window from one computer to the other....

You can send me all those monitors and I'll give it a whirl here! :) Ric

If you just have one graphic card and want to use two monitors with one
of them in VGA mode or S mode, you may want to try the command "xrandr".

Please check the manual.
