Re: [orca-list] problem using xclip on a regular tty

[Didier Spaier <didier slint fr>]

Hello Janina,

Also you can have several "virtual" monitors as you can have several
workspaces, all using the same physical screen.

For instance, if I type startx from tty1, an X server will start with a
display bound to tty7 and $DISPLAY=:0

Now I can go back to, say, tty2 (Ctrl+Alt+F2) and start another X server
like this:
DISPLAY=:1 startx

The new X server starts with a display bound to tty8.

I can switch between displays with Ctrl+Alt+F7 or Ctrl+Alt+F8

This is illustrated by this command's output:
didier[~]$ ps -ef |grep X
didier    1465  1446  0 mai04 tty1     00:00:00 xinit /home/didier/.xinitrc -- /usr/bin/X :0 -auth 
/home/didier/.serverauth.1446
root      1466  1465  5 mai04 tty7     01:33:50 /usr/libexec/Xorg :0 -auth /home/didier/.serverauth.1446
didier   23238 23219  0 13:22 tty2     00:00:00 xinit /home/didier/.xinitrc -- /usr/bin/X :1 -auth 
/home/didier/.serverauth.23219
root     23239 23238  0 13:22 tty8     00:00:03 /usr/libexec/Xorg :1 -auth /home/didier/.serverauth.23219
didier   23677 21788  0 13:33 pts/1    00:00:00 grep X
didier[~]$

All that using only the screen of my laptop.

But you can have only one orca running at a given time, so only one
"screen" can be read at a time, AFAIK.  

Best,

Didier

PS It also works with more displays, I just tried:

didier    1465  1446  0 mai04 tty1     00:00:00 xinit /home/didier/.xinitrc -- /usr/bin/X :0 -auth 
/home/didier/.serverauth.1446
root      1466  1465  5 mai04 tty7     01:33:58 /usr/libexec/Xorg :0 -auth /home/didier/.serverauth.1446
didier   23238 23219  0 13:22 tty2     00:00:00 xinit /home/didier/.xinitrc -- /usr/bin/X :1 -auth 
/home/didier/.serverauth.23219
root     23239 23238  0 13:22 tty8     00:00:05 /usr/libexec/Xorg :1 -auth /home/didier/.serverauth.23219
didier   24395 24376  0 13:40 tty3     00:00:00 xinit /home/didier/.xinitrc -- /usr/bin/X :2 -auth 
/home/didier/.serverauth.24376
root     24396 24395  4 13:40 tty9     00:00:01 /usr/libexec/Xorg :2 -auth /home/didier/.serverauth.24376
didier   24689 21788  0 13:41 pts/1    00:00:00 grep X
didier[~]$

But of course there are limitations, like the number of ttys available
and the amount of available RAM <smile>
