My configuration above provides 3 separate X displays and 3 separate |
| 30 |
desktops. |
| 31 |
|
| 32 |
The mouse pointer and focus moves among the three screens as you would |
| 33 |
expect, but each screen is a a separate X display. The three DISPLAY |
| 34 |
variables end up as ":0.0", ":0.1", and ":0.2". [There's only one X |
| 35 |
server running.] |
| 36 |
|
| 37 |
That means you can't drag a window from one screen to another, and a |
| 38 |
window can't overlap across two screens. |
| 39 |
|
| 40 |
It also means for a few applications you can only have the app running |
| 41 |
on one screen at a time. The vast majority of X apps don't care. But |
| 42 |
some, like Firefox (and other web browsers like Chrome and Opera), |
| 43 |
have added extra logic to prevent it. You'll have to ask the |
| 44 |
developers why, but I think it has something to do with their |
| 45 |
unwillingness to deal with file-locking when accessing config files. |
| 46 |
|
| 47 |
In _my_ particular configuration, I also have XFCE configured so that |
| 48 |
each of the three screens is configured with a pager that can flip |
| 49 |
through four virtual desktops independently of the other two screens. |
| 50 |
|
| 51 |
So I actually have a total of 12 virtual desktops (3 sets of 4). |
