MPX quick howto with Xephyr

Postby sossego » 2010-01-10 21:21

It took me forever to find this.

Be sure that Xorg has been upgraded to 7.4+.
Install Xephyr from the repositories.

Open a terminal.
Connect a second device to a free serial input- USB, Firewire,PS3, etc.

Code: Select all
xinput list

Keep note of each device and location.
Code: Select all
xinput create-master New

Code: Select all
xinput list

Look for the new Master. The pointer should appear in the middle of the screen.
Code: Select all
xinput reattach <number of device> <number of second master>


Enter the following in a terminal.
Code: Select all
Xephyr -ac -screen 640x480 -br -reset -terminate 2> /dev/null :1 &

Code: Select all
Xephyr :1 & export DISPLAY=:1; xterm

Grab a pointer and starta new session or application within Xephyr.
You'll have to do some playing around, but you can run a session within the new window with its own pointer.
There is also a keyboard interface with the new pointer if you wish to attach one.
Practical uses would be helping someone you know with Linux or teaching.
Applications also stay limited to the new work area. Very helpful if you need to run a lot of small programs but you want them out of the way.

Enjoy.

Edit: I was not aware of the previous MPX tutorial. This can be merged /added to the older tutorial if the moderators wish.
Let my desire and hope surpass my expectations;
And give me the strength to persevere through doubt.
Grant me the wisdom to exceed my bounds.
Let my eyes always see through the dream fog of childhood,
so that every moment may be treasured.
