Natty - Windows MCE remote triggering events to lirc and as a keyboard making mythtv frontend unusable

[mathieg2]

Binary package hint: xorg

Due to a recent change in either X or the kernel, my media center remote is now being picked up as a keyboard, as well as lirc. Therefore when using mythtvfrontend, boxee, xbmc I the cursor moves twice for every keypress.

I have temporarily resolved the issue by disabling lirc - but this means that the OK button which is mapped to keycode 352
is not picked up by X - I guess this is because it is over 255.

If I could remap 'ok' to the enter key - my problems would be solved - but I dont have a clue how to do this.

I imagine a lot of other people will experience similar issues once 11.04 is released - so it would be useful
if the re-mapping could be implemented as part of the ubuntu release.

Please feel free to re-assign this bug - I wasnt sure where to send it.

[Chris Boot (bootc)]

The correct fix for this in Natty is this:

echo lirc > /sys/class/rc/rc0/protocols

Just add that line to /etc/rc.local and it will be done at boot. This is not an Xorg bug but a side-effect of the kernel now understanding IR remote controls and generating keyboard events for them. You just disable the decoding and tell the kernel to send LIRC events and all is well.

I confirm that the fix above did cure my problem

[Niklas Rosenqvist (niklas-s-rosenqvist)]

how exactly is this fix supposed to be implemented? I'm relatively new to linux and I could need some further explaining. What I did to try to fix this problem is that I added the line "echo lirc > /sys/class/rc/rc0/protocols" in /etc/rc.local before the "exit 0" command. Is this the correct way to implement this since my remote still sends keyboard inputs (Antec Veris rm200, not MCE)?

[mathieg2 (graeme-salsaholics)]

What do you get when you enter the following command?

ls /sys/class/rc

You might have more than one remote control on your computer.

also try:

cat /sys/class/rc/rc0/protocols

repeat this for each directory found... rc0 rc1 rc2 etc

[Mario Limonciello (superm1)]

Can you please run the lirc update in natty-updates? It should fix this.
