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>

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>
