Firebox LCD Driver for LCDProc

networkBob

Greetings all,

I've got an XTM5 box (2.3.4 amd64) and I would like to keep the LED display backlight permanently ON.

If one of you has the modified sdeclcd.so file that removes the backlight timeout code, please post the file or post a link to the file.

Thank you!

Has someone gathered the DATA on this issue? I know the original spec I coded the driver from mentioned a low number of hours for the life of the backlight. Some of you seem to suggest that the technology has evolved over time, and that automatic time out should no longer apply. Maybe different hardware revisions of these Watchguard/Lanner boxes used backlights that could stay on on a continuous basis. Maybe the problem is only with the earliest boxes, and few people use those anymore. I am willing to provide a code fix (and work it upstream through lcdproc.org) to implement a parameter in the config file, if applicable, but I would like to know the hard facts. Is it a matter of opening the case and identifying the LCD manufacturer, and, from there, locate a suitable spec sheet?

I coded the driver as per this SDEC spec sheet: http://www.ktechs.net/pvt_filz/lcdproc/LMC-S2D20-01.pdf

Let me know…

@flecom:

I manage a ton of XTMs with actual watchguard software I assure you the backlight stays on 24/7

it's lcdproc that turns it off in the driver

@stephenw10:

That's true, it's the driver that turns off the back light and not the BIOS.

It would not be that hard to recompile the driver with the timer edited out if you really need that. I personally prefer it going out. If I see the LCD is lit that means the driver has crashed out for some reason.

Steve

You guys where 100% right.
I never used these boxes with the Watchguard software, only for a powerup test after receiving it for verifying
if the listed modelnr corresponds with the seller information.
Besides that, these boxes where immediately converted to pfSense, and that's why i never saw the LCD screens keeps on. ::)

OK, so… if it's the driver... is there a way to include a command to NOT turn it off or to change the timer value? Perhaps being able to set it to zero to keep it on, or to a number of seconds before it shuts off.

DeLorean

It would be nice if the option to keep on the LCD screen under settings was working.
So that you can decide if the LCD screen backlight must be kept on or off.

That's true. Since there are options set in the settings interface for LCDProc, I wonder if there isn't some way for the file to disregard it's internal clock for killing the backlight and just allow the settings to override it.

Where is the latest code source for the program? I don't know if I can properly write the changes, but I'll try.

stephenw10

Go to the source! ;D

http://lcdproc.cvs.sourceforge.net/viewvc/lcdproc/lcdproc/server/drivers/sdeclcd.c?view=markup

But yeah a code revision to enable or disable the backlight timer from the driver config would be appreciated by many. There can;t be that many people running the original X-Core models now.

It's here, now: https://github.com/lcdproc/lcdproc

So, this backlight timeout is only useful for the old X-Core boxes? What about the X-Core-e (x550e, x750e)? X-Peak?

stephenw10

The X-Peak may have a limited life but the display is different hardware. My X-Peak died of bad caps a while back anyway.

The X-e and newer models are all led backlight I believe so no problems.

I would not want to have it on all the time personally but a choice to do so seems reasonable.

–EDITED POST--

This might be the wrong way to disable the backlight off toggle because I am not a driver coder, but I have edited/compiled a sdeclcd.so that has "no timeout" on FreeBSD 10.3 (32 bit and 64 bit) and FreeBSD 11.1 (64 bit) virtual machines

So far the 32 bit works great on my X750e and the 64 bit works on XTM5 according to networkBob

Here's how I proceeded (from scratch on a new install of FreeBSD)


pkg install automake autoconf gcc git nano
cd ~
git clone http://github.com/lcdproc/lcdproc
cd lcdproc
nano server/drivers/sdeclcd.c
----- change BACKLIGHT_OFF to BACKLIGHT_ON on lines 650 and 676 then save CTRL-X, Y, ENTER
sh ./autogen.sh
./configure --enable-drivers=sdeclcd
make server

This will generate ~/lcdproc/server/drivers/sdeclcd.so which you can copy somewhere in order to download it to your pfSense box by FTP or whatever method you prefer.

If you don't want to compile it yourself, you can grab the ones I have compiled at the following links or as an attachment to this post

pfSense 2.3 (FreeBSD 10.3)

32 bit version : http://www.vizi0n.com/watchguard/sdeclcd.so.32bit.zip
64 bit version : http://www.vizi0n.com/watchguard/sdeclcd.so.64bit.zip

pfSense 2.4 (FreeBSD 11.1)

64 bit version : http://www.vizi0n.com/watchguard/sdeclcd.so.freebsd11.zip
32 bit version : none, pfSense has no 32 bit release since 2.4

You need to extract the zip file's content and move it it /usr/local/lib/lcdproc/
Then make sure that you run "chmod +x sdeclcd.so" to make it executable

Feel free to edit my post if the method I haved used is not the proper way to bypass that timeout in the driver.

@vizi0n:

I am not a driver coder, this might be the wrong way, but I have compiled a sdeclcd.so that has "no timeout" on a i386 FreeBSD 10.3 virtual machine.

So far it works great on my x750e.

All I did was edit "sdeclcd.c" and replace "BACKLIGHT_OFF" to "BACKLIGHT_ON" on lines 650 and 676

Hope this works for you

That made LCDProc fail on startup. If I went into the services status, it showed LCDproc not started, and when I tried to start, it just failed.

Error in the system log: Could not open driver module /usr/local/lib/lcdproc/sdeclcd.so: /usr/local/lib/lcdproc/sdeclcd.so: unsupported file layout

But I'm happy that you tried! Thank you for that.

stephenw10

On 32bit? ;)

Thank you so much for the effort, vizi0n. However, this did not work on my 64-bit XTM515 box.

As noted by dhoffman98, LCDproc failed to start after replacing the release sdeclcd.so file with your modified version. Maybe it has to do with the 64-bit architecture vs 32-bit. I do not possess the required knowledge to know.

I tried messing around with online C compilers but got super frustrated trying to find a way to compile to a .so file. It seems to me that eliminating the timeout would be more complicated than, say, increasing the timeout from 30 seconds to 300,000 seconds, although that would add a tiny amount of processor overhead.

stephenw10

Yes, you need a 64bit driver to run in 64bit. That error is what you see when you try to load a 32bit driver.

Steve

vizi0n

Yes this driver is for 32 bit, I can recompile it for 64 bit later tonight for you fancy 64 bit folks :P

vizi0n

I have updated my previous post with both drivers as separate attachments

32 bit version : http://www.vizi0n.com/watchguard/sdeclcd.so.32bit.zip
64 bit version : http://www.vizi0n.com/watchguard/sdeclcd.so.64bit.zip

Please confirm if the 64 bit works as I have no way to test it. Also make sure that you run "chmod +x sdeclcd.so" to make it executable

networkBob

Thank you, vizi0n. That worked on my XTM515 box (running 2.3.4 amd64)! Now the backlight stays on! I am happy and frankly kinda giddy. I appreciate your help.

Cheers

I apologize in advance if this is a stupid question. I opened the file "sdeclcd.so.64bit.zip" and noticed the "__MACOSX" folder. I don't have a Mac.
