[Thinstation-developer] RE: Xnest & X & session problems

[Miles R. <mr...@we...>]

will have better squiz over the weekend :o) 

but, at a brief look, I may have made a mistake.  possibly should be

        X_NUMBER=`ps -ef | grep "Xorg " | cut -f2 -d: | cut -f1 -d" "`
	x_NUMBER=$X_NUMBER `ps -ef | grep "Xnest "  | cut -f2 -d: | cut -f1
d" "`
        let XNEST_NUMBER=0
        for x in $x_NUMBER;
        do
                if [ "$x" -ge "$XNEST_NUMBER" ] ; then
                        let XNEST_NUMBER=x+1
                fi
        done

do you want to try and let me know?

the above is meant to get the next free available X Screen id.  so if there
is a X org session running at 

:2 and a xorg session at :3

it would go

for x in 2 3

so next available id would be 4.

Subject: Xnest & X & session problems

Miles,

I have been playing with my xnest & x session problems a little more.

They are based on setting up sessions as per our examples:
AUTOSTART=Off
SESSION_0_TYPE=icewm
SESSION_1_TYPE=x
SESSION_1_SCREEN=2
SESSION_1_X_SERVER=192.168.1.2
SESSION_1_X_OPTIONS="-indirect"
SESSION_1_AUTOSTART=Off

(The example shows these as X, but I have used XNEST) SESSION_2_TYPE=xnest
SESSION_2_XNEST_SERVER=192.168.1.3
SESSION_2_XNEST_OPTIONS="-query"
SESSION_2_AUTOSTART=Off

and running them both under replimenu and icewm.
Under replimenu:
x works
xnest doesn't

Under icewm:
neither works

If I comment out the SESSION_2_XNEST_OPTIONS line.
Under replimenu:
xnest doesn't work

Under icewm:
xnest does work

The xnest.fullscreen script is
CMD_FULLSCREEN="Xnest :\$XNEST_NUMBER -geometry $SCREEN_RESOLUTION -query"
which is why adding an OPTIONS="-query doesn't work 

Beyond all that, we should be able to run an xnest session from replimenu
and an x session from under a wm.

Is it something to do with the getfreescreen function in
thinstation.functions?

Here is the getfreescreen section of thinstation.functions

# Get Free XServer Number
getfreescreen()
{
	local X_NUMBER

        X_NUMBER=`ps -ef | grep "Xorg " | cut -f2 -d: | cut -f1 -d" "`
	x_NUMBER=$x_NUMBER `ps -ef | grep "Xnest "  | cut -f2 -d: | cut -f1
d" "`
        let XNEST_NUMBER=0
        for x in $X_NUMBER;
        do
                if [ "$x" -ge "$XNEST_NUMBER" ] ; then
                        let XNEST_NUMBER=x+1
                fi
        done
}

My scripting isn't that good, but I am assuming that there was an attempt to
get this code to find the existing Xorg sessions & then the Xnest sessions &
end up with all existing sessions. 

I can't work out how this will work. I can see how the X_NUMBER= line works
and how the next line gets the same info for Xnest, but I am assuming that
the x_NUMBER=$x_NUMBER <etc> is a concatenation (but is that how
concatenation works?) Also, in this case shouldn't it be $X_NUMBER and then
the for loop should be against $x_NUMBER.

I think I'm starting to get confused, so will leave it there at the
moment....
