Here is an lcdproc.inc that seems to fix the startup crash issue.

Not sure if this will work for everyone or if it isn't working right, but let me know how it could be improved.

It generates this rc.d script:

Code:

#!/bin/sh



#!/bin/sh
# This file was automatically generated
# by the pfSense service handler.

rc_start() {
sleep 5
/usr/bin/nice -20 /usr/local/sbin/LCDd -c /usr/local/etc/LCDd.conf
/usr/bin/nice -20 /usr/local/bin/php -f /usr/local/pkg/lcdproc_client.php &

}

rc_stop() {
pkill -f lcdproc_client.php

pkill -anx lcdexec
pkill -anx lcdproc
pkill -anx LCDd
sleep 1

}

case $1 in
start)
rc_start
;;
stop)
rc_stop
;;
restart)
rc_stop
rc_start
;;
esac

Not sure if this is the correct place to post this question but I'm new here so any help would be much appreciated.  I have a crystalfontz 634 running on pfsense 2.0.1 amd64 with LCDproc 0.5.5 pkg v. 0.9.4 installed.  At startup I see the crystalfontz info come up, then the blinking light in the top left.  After pfsense and LCDproc start up I see a bunch of garbage characters scroll down the lcd for like thirty seconds then just a blank screen.  I'm pretty sure I've got the right usb com port as the top left blinking light will just keep on if I switch to another one.  From the web settings I have it set to 4x20, CrystalFontz driver, 5 sec refresh, 9600 baud (tried default, same thing) and then default on the rest of the settings.  For screens I have "Enable Traffic Interface, WAN" and "Enable Hostname".  Here's the contents of LCDd.conf:

Code:

[server]
DriverPath=/usr/local/lib/lcdproc/
Driver=CFontz
Bind=127.0.0.1
Port=13666
ReportLevel=3
ReportToSyslog=yes
User=nobody
Foreground=no
ServerScreen=no
GoodBye="Thanks for using"
GoodBye="    pfSense     "
WaitTime=5
ToggleRotateKey=Enter
PrevScreenKey=Left
NextScreenKey=Right
ScrollUpKey=Up
ScrollDownKey=Down
[menu]
MenuKey=Escape
EnterKey=Enter
UpKey=Up
DownKey=Down
[CFontz]
Device=/dev/cuaU0
Size=20x4
Contrast=350
Brightness=1000
OffBrightness=50
NewFirmware=no
Reboot=no
Speed=9600

Anybody have any ideas about why it's doing this?

[nicktlloyd]

Ok, if anyone else has a crystalfontz 634: make sure you set the contrast over 50% or you won't see ANYTHING.  DON'T LEAVE IT ON DEFAULT.

Bumping this so people can see and try my fixed lcdproc.inc

I was wondering if we could get that and the 64bit SDECLCD driver put in the real package.

[stephenw10]

Hmm, this looks like spam but doesn't have any links.  
Please re-phrase this if you are really asking.

Steve

Edit: It was spam then!

Hi !
congratulations for the work !
I am Celestix Scoprio X MSA 5000 user and the box run very nice with pfsense 2.0.1
...but..the lcd display don't work !
I tried different drivers ... but nothing ...
is a USB display of 40 x 2 (with 3 led for (1) attention / (2) HDD / (3) ON )
Would it be possible to control it with lcdproc?
Many Thanks !

[stephenw10]

Possibly. We need more information. Anything written on the the LCD unit itself? Any windows drivers that might provide a clue?

Steve

The display manufactured is varitronix
Unfortunately, I have never written anything ...
you can not find any drivers...even windows ...

[stephenw10]

The Varitronix MGLS19264 used in this box appears to use a HD61202 chip which is compatible with the KS108. This is a graphical LCD and lcdproc is setup to drive character based displays. However all may not be lost. It might work using the glcdlib driver:
http://lcdproc.sourceforge.net/docs/stable-0-5-x-user.html#glcdlib-howto
This appears to support the ks0108. However it looks like there would be quite a lot of additional packages/drivers needed.
This is beyond my usual level of tinkering.

Many Thank for the Info !
I can Try !

[Gradius]

Crystalfontz released the new 735, they are much better in quality and can emulate 635, but not 100% AFAIK.

I hope they gets supported.

See the quality:

I was looking to see if there was a new thread for the 0.5.5 package and couldnt find it so I could post this question in it. Maybe search fail on my end not sure,

Would someone know how to get this to work with LCD Proc?

Any news / progress on the 4 Leds of the CFA635 ?

I modified the lcdproc_client.php to work with the CFA635 (driver CFontzPacket) inclusive the 4 LEDs. I also changed the IPSec detection for the IPSec screen (it was not working in the current version).
Led 1 : CPU usage
Led 2 : Interface status
Led 3 : IPSec status
Led 4 : Gateway status
 
Maybe someone can include this into the package ?

This works Great even on latest version of DEV package.  Thanks for posting this! Its nice to have the lights working and doing something useful. Anyone know how I could edit this further to show Open VPN for that LED instead of IPSEC and then gateway status show if snort is running or not? Snort fails sometimes after updates and it would be nice to have green running and red light not running.. Also as an added bonus it would be nice to have an openvpn screen that shows users ect. I know that is diff and would most likely take more work but would be good to have .. Any help would be greatly appreciated.

Any news / progress on the 4 Leds of the CFA635 ?

I modified the lcdproc_client.php to work with the CFA635 (driver CFontzPacket) inclusive the 4 LEDs. I also changed the IPSec detection for the IPSec screen (it was not working in the current version).
Led 1 : CPU usage
Led 2 : Interface status
Led 3 : IPSec status
Led 4 : Gateway status
 
Maybe someone can include this into the package ?

Looks quite interesting. It makes the code quite specific to the Crystalfonz LCD though. Though it's using the correct 'out' function that is part of lcdproc the driver is free to interpret the value sent in whatever way it likes to drive the LEDs. Other drivers will not be compatible.
Edit: Actually I see it only outputs if the correct driver is in use

Re-writing the function outputled_ipsec () to query openvpn instead doesn't look too tricky. You just have to find out which config values to look at. Which I don't! 
Perhaps look at how the openvpn status page does it.
