Hi,

thank you both for your responses.
I will try to answer in-mail.

I tried this,  but the biggest problem (for me) was to be able to
distinguish between different instances of xmobar running.
I solved it with (in the startup shell script):

xmobardown=`ps ax |grep xmobar|grep -v up|awk '{print $1}'`
for proc in ${xmobardown}
do
  kill -9 ${proc}
done
xmobar ~/.xmobardownrc &

I am sure there is a more elegant way to do it, maybe using pidof (it
didn't work for me tho) but this works, more or less.
You say you use 4 instances of xmobar? Can I put xmobar also in
"vertical"? That would be nice ;)

I did try this way, but it doesn't work. I tried it again after
receiving your mail, and... it still doesn't work :)
Even if I use spawnPipe and I call it someway... something like
myUncleJoe <- spawnPipe "xmobar ~/.xmobardownrc"
it still doesn't work: once I hit mod+q the number of instances of
running xmobar increases.

Next issue is the tray: I am using trayer (for things like nm, volume
applet, since multimedia keys on this lenovo laptop do not return
anything xev is happy to tell you about even tho they used to work
with gnome/kde).
Are there other options the list knows of?

Thanks,
