[mythtv-users] iMON & ir-keytable on Fedora 15

Fri May 27 08:11:29 UTC 2011

Hello list,
I've got an Antec case with a Soundgraph (iMon) LCD & IR receiver. I
recently upgraded from Fedora 13 to Fedora 15, and I read over some of
Jarods changes in the imon module (particularly the removal of the
ir_protocol option). I was using this option to set the device to MCE
mode (ir_protocol = 1) in Fedora 13 and running lircd using the devinput
driver.

I have been attempting to get the device back in RC-6 mode with no
success so far. ir-keytable sees the device:

Found /sys/class/rc/rc3/ (/dev/input/event7) with:
        Driver imon, table rc-imon-pad
        Supported protocols: RC-6
        Enabled protocols:
        Repeat delay = 500 ms, repeat period = 33 ms

And I can read the existing table:

But I tried to change the protocol and ir-keytable just seg faults:

# ir-keytable -d /dev/input/event7 -s /sys/class/rc/rc3 -p rc6
Segmentation fault (core dumped)

Under the debugger it looks like this (not sure how helpful it is)

GNU gdb (GDB) Fedora (7.2.90.20110429-36.fc15)

I was able to write the rc6_mce table to the device (but ir-keytable
still seg faults at the end). I also cannot perform a test (-t) for the
same reason.

Has anyone been able to get imon working under Fedora 15?

Thanks,
Erik
