[SOLVED] LCDproc + Antec Fusion Black

nerditup · 2010-06-04 01:47:12

I'm not sure if anyone else has had any luck with getting their LCD Display working but I've been having a tough time!

I have been following the instructions on how to install the LCD Display found here:

http://codeka.com/blogs/index.php/2007/ … patch_v0_1

I've completed every step except when I get to the last one,

~/lcdproc-0.5.2$ sudo LCDd -f -r 4

I get the following error:

[nerditup@htpc lcdproc-0.5.2]$ sudo LCDd -f -r 4
sudo: LCDd: command not found

I've looked everywhere and I can't find LCDd in any folder. Some resources say it's in /etc/init.d/ but as we know Arch doesn't use this folder. It's not in /etc/rc.d either.

It just doesn't make sense that it just wouldn't install! Unless I'm missing a prerequisite somewhere?

Thanks!

I just installed lcdproc from the AUR and pacman -Ql lcdproc says among others:
lcdproc /usr/sbin/
lcdproc /usr/sbin/LCDd

Awesome, that works. I'm able to run LCDd now. I'm going to work on this for a bit and see if I need to patch it for my specific device to work.

Would I still be able to patch something downloaded from AUR?

demian · 2010-06-04 14:21:24

Sure, you'll just have to add the patching step to the PKGBUILD build() part.
Or get the sources, patch them, repack them and use them as source in the PKGBUILD.

I've installed lcdproc from the AUR with yaourt. The latest AUR update as of yesterday shows that it has a patch for imonlcd built in.

I think I may have something working, but it's hard to tell. I haven't gotten any errors... However before, the LCD would have some random things light up. Now that I've installed this program, error free, by following these instructions: http://lukedoomer.blogspot.com/2010/05/ … linux.html the screen is now blank (nothing is lit except the backlight of course).

But when I load everything up, nothing shows up on the display? No CPU, no memory, nothing.

Here's some information, not sure what else needs to be running?

From my /etc/LCDd.conf

...
DriverPath=/usr/lib/lcdproc/
...
Driver=imon

[imon]
...
# select the device to use

I think it goes like this. In /etc/LCDd.conf use the imonlcd driver (not imon). And in the [imonlcd] section set Protocol=1.

...

[server]

DriverPath=/usr/lib/lcdproc/

Driver=imonlcd
...

[imonlcd]
# Specify which iMon protocol should be used [legal: 0=15c2:ffdc device,
# 1=15c2:0038 device; default: 0]
Protocol=1

Device=/dev/lcd0

#Contrast=200

#Size=96x16

#Backlight=on

#DiscMode=0

For infrared mouse, remote keys and the volume knob you need lirc:

pacman -S lirc lirc-utils
ln -s /usr/share/lirc/remotes/imon/lircd.conf.imon-antec-veris /etc/lirc/lircd.conf
/etc/rc.d/lircd start
(check with irw in terminal with user permissions)

To start up properly on boot, put this in /etc/rc.conf:

DAEMONS=(....  lcdd lircd)

and this in /etc/rc.local:

lcdproc &

Then use your desktop tools (e.g. kdelirc) to set up what happens when you use the remote keys and the volume knob.

Thanks everyone for the help, I got it working.

Aedit, it was the driver I was using that was the problem in the end. It makes sense too because as you've seen in here,

[nerditup@htpc ~]$ sudo lsusb
Bus 002 Device 003: ID 15c2:0038 SoundGraph Inc. GD01 MX VFD Display/IR Receiver

The device ID corresponds to the driver in /etc/LCDd.conf seen here,

[imonlcd]
# Specify which iMon protocol should be used [legal: 0=15c2:ffdc device,
# 1=15c2:0038 device; default: 0]
Protocol=1

Should have seen that! Anyway, thanks again for all the help.

Hi

Don't you have to modify permissions on /dev/lcd0 ?

I have

ls /dev/lcd0 -lha
crw------- 1 root root 180, 0 Feb 26 11:15 /dev/lcd0

and cannot use it i.e. with mythbackend's lcd output ...

I'm using the same settings as nerditup and it worked perfectly in Debian Sid, but I'm unable to get this to work in Arch. Nothing ever appears on the LCD screen and trying to access the lcd0 device directly just locks up whichever application or terminal was trying to access it. dmesg shows:

Has anyone had this issue or had any trouble with the LCD recently?

ict · 2011-05-07 15:51:52

Yes, same thing here. Worked fine before. This seems related, but I haven't found a solution yet: http://comments.gmane.org/gmane.comp.ha … lirc/11411

Edit: OK, this fixes it for me: Find /usr/bin/ir-keytable and rename it to something else. Create a shellscript or some other empty program and name it ir-keytable so it can still be called but does nothing. Reboot.

I've been speaking with the LIRC people. Jarod Wilson found that it's a kernel module bug and a patch has been submitted for inclusion in the kernel so hopefully it'll start working for us again soon.

boomshalek · 2011-10-02 22:03:04

Has this kernel bug been resolved with the release of kernel 3.0 ?

Would be another reason to go for a system upgrade.
