Regarding Xephyr

[Riza Dindir]

Hello,

I thought that it will set the background color, and this will be it.

I added an xterm in there like so (this is in a file run.sh and I am
running this shell script with (DISPLAY=:1 sh run.sh)

xsetroot -solid "#006060"
xterm -geometry +20+40

With this the background color turns to a blue then the background
goes black. But the xterm is seen, and if I exit xterm, the session
ends.

But if I do this (notice the ampersand at the end of the xsetroot line)

xsetroot -solid "#006060" &
xterm -geometry +20+40

the background color stays, and is not changed to black as it is the
case with the above example.

Regards,
Riza
