Hi Michael,

thanks for the response!

I have managed to get as far as this:

----------------------------

Variables {
     tick 500
     tack 100
}

Widget TimerW {
    class 'Timer'
    expression n=LCD::GPI(1);nkey=n!=0?n:nkey
    active 1
    update 100
}

Widget Eth0 {
     class 'Text'
     expression (netdev('eth0', 'Rx_bytes', 500)+netdev('eth0', 
'Tx_bytes', 500))/1024
     prefix 'eth0'
     postfix 'B'
     width  9
     precision 0
     align 'R'
     update tick
}

Widget Eth0Bar {
     class 'Bar'
     expression  netdev('eth0', 'Rx_bytes', 500)
     expression2 netdev('eth0', 'Tx_bytes', 500)
     length 9
     direction 'E'
     update tack
}

Widget CPU {
     class  'Text'
     expression  uname('machine')
     prefix 'CPU '
     width  9
     align  'L'
     update tick
}

Widget Busy {
     class 'Text'
     expression proc_stat::cpu('busy', 500)
     prefix 'CPU'
     postfix '%'
     width 10
     precision 1
     align 'R'
     update tick
}

Widget BusyBar {
     class 'Bar'
     expression  proc_stat::cpu('busy',   500)
     expression2 proc_stat::cpu('system', 500)
     length 9
     direction 'E'
     update tack
}

Widget GPO_kf1 {
    class 'GPO'
    expression button_text=nkey==3?uptime('%d days 
%H:%M:%S'):button_text;nkey==3?1:0
    update 300
}

Widget GPO_kf2 {
    class 'GPO'
    expression button_text=nkey==4?strftime('%a,%d/%m 
%H:%M:%S',time()):button_text;nkey==4?1:0
    update 300
}

Display picoLCD20x2 {
    Driver   'picoLCD'
    Size     '20x2'
    Contrast  0
    Backlight 1
    Icons     6
}

Layout L20x2 {
    Row1 {
         Col1 'Eth0'
     Col11 'Busy'
    }
    Row2 {
     Col1 'Eth0Bar'
     Col11 'BusyBar'
    }
Layer1 {
    Timer1 'TimerW'
    GPO2       'GPO_kf1'
    GPO3       'GPO_kf2'
}
}

Display 'picoLCD20x2'
Layout 'L20x2'

-------------------------------------------------

I have now upgraded to the SVN version off the site: 
lcd4linux-0.11.0-SVN as I compiled it myself.

I now can display the desired content on the LCD but the software seems 
to SEGFAULT if I don't use the 'Layers'???

Additionally with the content provided I can't read anything from the 
F1-F4 keys either :-(

Regards,

Kaya
