[gentoo-user] dual monitors and dual desktops

[-- Attachment #1: Type: text/plain, Size: 685 bytes --]

Hi,
I have a laptop and an external monitor.
I would like to have both monitors showing different desktops.
My aim is to have IRC and Email client on one side, and my shell and
programming stuff on the other side.
Currently I managed to do a big virtual workspace with XRANDR, but it
stretches the browser and it is hard to setup correctly.
I'm a Fluxbox user, and didn't find a way to define that starching the
window, will not stretch outside of the monitor I'm on.
This is why I would like each monitor have it's own desktop.

Thanks,
Kfir

virtual dual monitors:
xrandr --output LVDS1 --primary --mode 1280x800 --pos 0x0 --auto --output
VGA1 --mode 1920x1080 --pos 448x0 --primary

Thanks for your reply.
This program does just what xrandr does.
I didn't find a way to separate screens. It seems to define by default a
virtual workspace, and let you just put both screens in this virtual
workspace.
The command at the bottom of this mail does just that.

I want that the monitors will not show the same workspace. Both should show
different desktops.
It is like running xorg twice.

Re: [gentoo-user] dual monitors and dual desktops

[mindrunner]

I am also using a notebook with an external screen when i am at home.
Till today I was not able to configure it correctly and comfortable.
(Tried with radeon and fglrx driver)

My wonderful working solution is One computer for every screen. :))
Connect all them with synergy and it seems to be one computer! :)

I am running a synergy setup with gentoo, mint, osx and windows8 and it
is much better than every multi monitor solution.

I know this is more a workaround as a solution, but multi monitor with
linux is crap, and synergy is a wonderful tool! :)))

Yes, this is a viable solution, but not if you have the laptop and no
desktop.
When I had workstation I also did use synergy.
But now I have just an external monitor, and I need this solution.

Here's how I do it using Xorg.config

----------------------------------------------------------------------
Section "ServerLayout"
        Identifier     "Triple"
        Screen      0  "Samsung0"
        Screen      1  "Samsung1" rightof "Samsung0"
        Screen      2  "Acer" leftof "Samsung0"
        InputDevice    "Mouse0" "CorePointer"
        InputDevice    "Keyboard0" "CoreKeyboard"
EndSection
----------------------------------------------------------------------

There are three Device sections (one for one video card, and one for
each of the DVI outputs on a second video card).  There are then three
corresponding Screen sections (named Samsung0, Samsung1, and Acer).

Dunno anything about xrandr...

Does this setup really separate the screens to 2 desktops and not one big
virtual desktop?

My configuration above provides 3 separate X displays and 3 separate
desktops.

The mouse pointer and focus moves among the three screens as you would
expect, but each screen is a a separate X display.  The three DISPLAY
variables end up as ":0.0", ":0.1", and ":0.2". [There's only one X
server running.]

That means you can't drag a window from one screen to another, and a
window can't overlap across two screens.

It also means for a few applications you can only have the app running
on one screen at a time. The vast majority of X apps don't care. But
some, like Firefox (and other web browsers like Chrome and Opera),
have added extra logic to prevent it. You'll have to ask the
developers why, but I think it has something to do with their
unwillingness to deal with file-locking when accessing config files.

In _my_ particular configuration, I also have XFCE configured so that
each of the three screens is configured with a pager that can flip
through four virtual desktops independently of the other two screens.

So I actually have a total of 12 virtual desktops (3 sets of 4).

Searching the terminal window opened 6 hours ago on one of the 12
virutal desktops sounds like fun :D

It's not as bad as it sounds. I rarely use more than 2 virtual
desktops, and depending on what I'm doing, there's an informal
"system": when doing development the left monitor is for looking at
PDF datasheets, center monitor is for edit/build source files, right
hand monitor is for "running" the program.

When I get interrupted by a phone call or visitor and need to do
someting else temporarily, I flip one or more of the screens to a
different virtual desktop.

It's sort of like a CPU for which you have a reguster usage convention
and a stack to push "in-use" registers onto when you get interrupted
or have to switch contexts.

If I recall correctly, USE=xinerama informs X clients to take multiple
monitors into account when maximising. I have it enabled globally but i
not sure which packages really need it.

Hi,
Ok, some progress.
Compiling Fluxbox with xinerama use flag result few good things.
Dragging a window to one screen, maximizes it automatically to the size of
the screen.
Now if I toggle maximization, it will be done on the screen the window is
in.

So now I can work with 2 screens.

Is it possible to have each screen in different desktop?

Regards,
Kfir

The command I use:
xrandr --output LVDS1 --primary --mode 1280x800 --pos 0x0 --auto --output
VGA1 --mode 1920x1080 --pos 1280
