[lcd4linux] problems with first line on 20x4

[Leszek100tka <ha...@10...>]

Hello,

I have a 20x4 lcd display (of course hd44780), my config looks like something 
here below (I know that it should be written in a different way, but now i 
really dont know how:):


Widget Load1 {
    class 'Text'
    expression loadavg(1)
    prefix 'Load: '
#   postfix loadavg(1)>1.0?'!':' '
    width 10
    precision 2
    align 'L'
    update tick
}

Widget Load2 {
    class 'Text'
    expression loadavg(2)
    prefix ' '
    width 5
    precision 2
    align 'L'
    update tick
}


Widget Load3 {
    class 'Text'
    expression loadavg(3)
#    postfix loadavg(1)>1.0?'!':' '
    width 5
    prefix ' '
    precision 2
    align 'L'
    update tick
}


Widget Eth0r {
    class 'Text'
    expression (netdev('eth0', 'Rx_bytes', 500)/1024
    prefix 'Rx: '
    postfix ' '
    width 10
    precision 0
    align 'R'
    update tick
}

Widget Eth0t {
    class 'Text'
    expression (netdev('eth0', 'Tx_bytes', 500)/1024
    prefix 'Tx: '
    postfix ' '
    width 10
    precision 0
    align 'R'
    update tick
}



Widget Uptime {
    class 'Text'
    expression uptime('%d days %H:%M:%S')
    width 20
    align 'R'
    prefix 'Up '
    update 1000
}



Layout L20x4 {
    Row1 {
        Col1  'Uptime'
         }
    Row2 {
        Col1  'Load1'
        Col11 'Load2'
        Col16 'Load3'
         }
    Row3 {
#       Col5 exec('cat /home/hardtmuth/my_files/temp_temp/lala, 1000)
         }
    Row4 {
        Col1 'Eth0r'
        Col11 'Eth0t'
         }
}

Display 'HD44780-generic'
Layout 'L20x4'
Variables {
   tick 500
   tack 100
   minute 60000
}

and the problem is that there is something wrong with the first line on LCD. 
Now I have on the first line 12:07 some spaces and at the end of the line 
6:03:15 (counting up - its uptime). I see that its really messed up, because 
there should be up days 0 6:03:15.

When i`ve uncommented Row3 / Col5 with that exec formula, the uptime line is 
displayed correctly. 

Why there is some connections between I and III line? sometime i`ve noticed 
that when i start lcd4linux, the display looks good, then i restart lcd4linux 
and first line is messed up.

Next i`ve problem with reading data from file, i`ve temperature in one file. 
I`m trying do read it with exec and cat, no results only some garbage:

sh: -c: line 1: syntax error near unexpected token `)'
sh: -c: line 1: `cat /home/hardtmuth/my_files/temp_temp/temp_raw.txt, 1000)'
exec error: could not read from pipe 
'cat /home/hardtmuth/my_files/temp_temp/temp_raw.txt, 1000)': Success

and doing this in a different way, by file::readline, i get:

Evaluator: unknown function 'file::readline' in 
<file::readline('/home/hardtmuth/my_files/temp_temp/temp_raw.txt', 1000)>

what am i doing wrong? Should I pass when i was compiling lcd4linux arguments 
with plugins to include or by default all plugins are compiled in?

Sorry for huge post, but i think that posting in one huge post is better that 
few smaller :).

Thanks for help.
