Hi all, recently I decided to upgrade my frontend with and SSD
to speed up bootup and silence it a bit more.<br>
After this update something changed in I guess the kernel
since after that I get symptoms which look like the up-arrow
is constantly pressed on a keyboard. I was able to determine
it was the VFD that's causing these symptoms, however I don't
know how to get rid of it.<br>
When I boot back in the old system which was Ubuntu 12.04 with
kernel 3.2.something everything is ok.<br>
I cannot get that kernel installed in Ubuntu 12.10 and
everything that's 3.4 or higher seems to cause these problems.<br>
<br>
Did anyone with this VFD experience the same problems? If so,
how did you get them solved?<br>
<br>
Thanks in advance,<br>
<br>

I don't know which SoundGraph model you have, and
unfortunately there are several different models, some of
which share the same USB ID (15c2:ffdc), but the driver uses
different, incompatible methods for driving the different
displays. There is a module called 'imon' (kernel config
symbol ir_imon) which has a parameter called display_type
which I had to set to 1 in order for the VFD to work. The
default autodetect (0) didn't work for me. Check your
distribution documentation for how to configure module
parameters.<br>

I got the one in the silverstone LC16M(15c2:0036) and it seems I'm
not the only one experiencing these problems.<br>

It's actually kernel 2.6.32 that works ok all later seem to screw
this up.<br>
Changing the setting via module parameters doesn't help with the
issue which also occurs on other linux(fedora 18) with a recent
kernel.<br>
I wonder why there seem to be so little users with problems....<span class="HOEnZb"><font color="#888888"><br>

Did you try it with a generic kernel, or only with a Fedora-specific kernel?<br>
<br>I found this post from Jarod Wilson, who did a lot of the work to merge the lirc code into the kernel: <a href="http://wilsonet.com/?page_id=95">http://wilsonet.com/?page_id=95</a> Maybe it will give you some ideas about where to look or what to try next.<br>
