Re: [lcd4linux] Pertelian X2040 on tinycore linux

[Nathan B. <nat...@gm...>]

Hi there Rupert,

Thanks for your help! I will definately look into pertd. If you want some
advice on how to build lcd4linux on ubuntu: There are changes in the svn
repo that dont seem to have made it into RC2. This gives an "undefined
reference to `rdtscl'" error, but after some research I found that this
problem had already been addressed and patched. I just needed to checkout
the latest version from svn. Also, I can remember needing to install a
'libXXXXX' package with apt-get, but cant quite remember what it was..
'libtool', maybe? Also, if you wanted to compile it without any extraneous
dependencies, you can just use './configure --with-plugins=XXXXX', and
specify the 1 or 2 that you need.

I actually got it to work 2 minutes after pressing send on the last email I
wrote ... It turns out my thin client was still overloaded with perl, mysql
and sqlite, since it only has 128MB RAM, some of which is used as the file
system. But I rebooted it, and everything seems to be working smoothly :)

Now just to code a shell-fm plugin and design a layout ...

Cheers,
Nathan B


Well, you got further than me, I couldn't even get lcd4linux to build on my
Ubuntu Karmic box due to dependency issues and sadly no one on this list
replied to my queries.

I ended up using the pertd application developed by some dude over at
Pertelian:

http://www.pertelian.com/joomla/index.php?option=com_content&task=category&sectionid=7&id=23&Itemid=49

(check the community download link as well - though the above link lists all
the programs you'll need)

It actually works quite well, there are two versions, pertd and pertd2.
IIRC pertd takes input from simple takes files stored in /var (the readme is
very comrehensive) whilst pertd2 takes input from a fifo pipe. I could never
get the fifo pipe to work, so I stuck with pertd instead. It works really
well and has been running 24*7 on my Intel DM501 (the newer version of the
Intel Atom 330) for about a month non-stop. It seems to only use a small
amount of CPU and RAM so I am happy.

The quality isn't brilliant, the text flashes as it scrolls and it there are
some extraneous characters as new text enters the screen to scroll along,
but overall I find it ace. I use bash scripts to update the text files, the
scripts being run via a cron job.

Currently it displays:
Line1: sys load 1min 5 mins and 15 mins, memory usage
Line2: temp of CPU, Northbridge and HDD from lm-sensors
Line3: Currently Recording / Next Recording and Scheduled Recording from
mythtv (via mythstatus) since the box is primarily a mythtv box
Line4: Any WARNING error message from syslog and if that is empty, a check
that the internet is up and disk space usage info.

Overall, I would highly recommend it. You might get nice looking stuff out
of lcd4linux, but since I couldn't even build it, I gave up.

Hope this is usefull.
Rupert
