How to pass args to startxfce4?

[npc]

I'm using slim as a session manager and it reads ~/.xinitrc.
I've set 3 different server layouts, tv-out only, lcd only and dual-head lcd+tv and I'd like to choose between them by hitting F1 at SLiM's login screen. But, to do so, i need to add something like "-layout some_layout" to startxfce4-containing lines inside ~/.xinitrc.
Thus, it would look something like this:

Code: Select all

DEFAULT_SESSION=startxfce4

case $1 in
xfce4)
        exec startxfce4 -- -layout lcd-only
        ;;
xfce4-tv)
        exec startxfce4 -- -layout tv-only
        ;;
xfce4-tv-lfp)
        exec startxfce4 -- -layout tv-lcd
        ;;
*)
        exec $DEFAULT_SESSION
        ;;
esac

Does anybody know if it's possible to pass such args to startxfce4 as we do to startx?

Thanks in advance.

Isn't startxfce4 just a script? It used to be at any rate, if it is can you edit it to accept the parameters?

There should be no need to edit startxfce4, simply invoke it with client flags prior to and server flags following a double hyphen and the script should handle the flags appropriately.

All i've got is a server flag, the -layout one, i think.
Should it be then "startxfce4 <nothing> -layout layoutname --" ?

I tried "startxfce -layout layoutname --" and it retuned an error, without the "--" it startups, but ignores the -layout arg.

Thanks.

Code: Select all

startxfce4 -- -layout $layout

[npc]

Code: Select all

startxfce4 -- -layout $layout

It doesnt work. It returns:

Fatal error:
Unrecognized option: --

Thanks.

Found a solution! Partial at least.

I was hacking around the startxfce4 script, and i've found this $SERVERRC variable... hum...
So i tried the following from the console:
SERVERRC="-layout lfp-tv $SERVERRC" startxfce4

And guess what? It works! Xorg sees my other layout and loads it accordingly.

So, the .xinitrc, to allow slim to load xfce4 using one of the layout options passed by the %session variable.

Code: Select all

# the following variable defines the session which is started if the user
# doesn't explicitely select a session
DEFAULT_SESSION='startxfce4'

case $1 in
xfce4)
        export SERVERRC="-layout lfp $SERVERRC"
        ;;
xfce4-tv)
        export SERVERRC="-layout lfp-tv $SERVERRC"
        ;;
xfce4-vga)
        export SERVERRC="-layout lfp-vga $SERVERRC"
        ;;
*)
        exec $DEFAULT_SESSION
        ;;
esac
exec $DEFAULT_SESSION

And guess what? It DOESN'T work. Xfce loads fine, but xorg seems not to care about the $SERVERRC variable set on .xinitrc, it only loads the default serverlayout. On a term, echo $SERVERRC returns the exact value set in .xinitrc.
What the heck is going on???

Thanks again.
