    NVidia drivers, TBS tuner card and IR-keytable

    Hello,
    I am running Mythbuntu 12.04, and recently acquired a TBS tuner card (the 6281 I believe) and set it up with MythTV. Having failed to configure the IR receiver with LIRC, I instead turned to IR-keytable. After some tweaking, I got a very pleasing result. I decided that my Mythbuntu machine needed HDMI output, so I acquired a cheap NVidia GeForce 210 card. I booted it up, set up the driver and got lovely HD video and audio. Now, however, IR-keytable no longer works. Even after reinstalling the tuner card's drivers three times (including downloading an updated version from their website), ir-keytable -t shows up absolutely nothing.
    I get the feeling that I might be overlooking something simple. Part of me suspects that it might be a physical problem, caused by carelessness in installing the graphics card, but I'm certainly hoping that that's not the case.

    This is the keytable I'm using:
    Code:
    # table tbs6981, type: NEC
    0x9f   KEY_ESC
    0x99   KEY_ENTER
    0x84   KEY_ESC      #Power
    0x94   KEY_MUTE
    0x87   KEY_1
    0x86   KEY_2
    0x85   KEY_3
    0x8b   KEY_4
    0x8a   KEY_5
    0x89   KEY_6
    0x8f   KEY_7
    0x8e   KEY_8
    0x8d   KEY_9
    0x92   KEY_0
    0x80   KEY_ESC   #Back
    0xd4   KEY_DELETE
    0x81   KEY_UP
    0x88   KEY_DOWN
    0x90   KEY_LEFT
    0x82   KEY_RIGHT
    0x96   KEY_UP   #CHANNELUP
    0x91   KEY_DOWN   #CHANNELDOWN
    0x93   KEY_RIGHTBRACE   #VOLUMEUP
    0x8c   KEY_LEFTBRACE   #VOLUMEDOWN
    0xdd   KEY_F10   #TV
    0x9d   KEY_F11   #ZOOM
    0x95   KEY_FAVORITES
    0x9b   KEY_MODE
    0x9e   KEY_M   #MENU
    0x9c   KEY_S   #EGP
    0x97   KEY_T   #SUBTITLE
    0x9a   KEY_CAMERA
    0x83   KEY_R   #RECORD
    0xde   KEY_P   #Play
    0x98   KEY_P   #Pause
    0xdc   KEY_ESC   #Stop
    0xdb   KEY_COMMA   #REWIND
    0xda   KEY_DOT   #FASTFORWARD
    0xd9   KEY_UP   #PREVIOUS
    0xd8   KEY_DOWN   #NEXT
    Thank you for reading this, and I hope someone can help me figure out what's going on.

    Re: NVidia drivers, TBS tuner card and IR-keytable

    What is the output of ir-keytable (without the -t) and "ls -l /sys/class/rc". Also, what are your remote settings in /etc/lirc/hardware.conf.

    Thanks for the reply.

    ir-keytable doesn't show up anything out of the ordinary, I think:
    Code:
    Found /sys/class/rc/rc0/ (/dev/input/event2) with:
        Driver saa716x, table rc-tbs-nec
        Supported protocols: NEC RC-5 RC-6 JVC SONY LIRC other 
        Enabled protocols: NEC RC-5 RC-6 JVC SONY 
        Repeat delay = 500 ms, repeat period = 125 ms
    There's one file in /sys/class/rc:
    Code:
    lrwxrwxrwx 1 root root 0 Apr  1 18:01 rc0 -> ../../devices/pci0000:00/0000:00:1c.3/0000:04:00.0/rc/rc0
    If I'm using ir-keytable, is /etc/lirc/hardware.conf still relevant? If so, that might be the problem, because it's not set up.
    Code:
    # /etc/lirc/hardware.conf
    #
    #Chosen Remote Control
    REMOTE="None"
    REMOTE_MODULES=""
    REMOTE_DRIVER=""
    REMOTE_DEVICE=""
    REMOTE_SOCKET=""
    REMOTE_LIRCD_CONF=""
    REMOTE_LIRCD_ARGS=""
    
    #Chosen IR Transmitter
    TRANSMITTER="None"
    TRANSMITTER_MODULES=""
    TRANSMITTER_DRIVER=""
    TRANSMITTER_DEVICE=""
    TRANSMITTER_SOCKET=""
    TRANSMITTER_LIRCD_CONF=""
    TRANSMITTER_LIRCD_ARGS=""
    
    #Enable lircd
    START_LIRCD="false"
    
    #Don't start lircmd even if there seems to be a good config file
    #START_LIRCMD="false"
    
    #Try to load appropriate kernel modules
    LOAD_MODULES="true"
    
    # Default configuration files for your hardware if any
    LIRCMD_CONF=""
    
    #Forcing noninteractive reconfiguration
    #If lirc is to be reconfigured by an external application
    #that doesn't have a debconf frontend available, the noninteractive
    #frontend can be invoked and set to parse REMOTE and TRANSMITTER
    #It will then populate all other variables without any user input
    #If you would like to configure lirc via standard methods, be sure
    #to leave this set to "false"
    FORCE_NONINTERACTIVE_RECONFIGURATION="false"
    START_LIRCMD=""

    Re: NVidia drivers, TBS tuner card and IR-keytable

    Sorry, I was thinking you were trying to use lirc. And lirc is not set to start up? There's a weird thing in the lirc startup script where it will change the enabled protocols to just 'LIRC' if LOAD_MODULES is true. So if lirc start script is running, it might be doing that.

    Looks like LOAD_MODULES is indeed true. I'll change that now and see what happens...

    EDIT: Nope, still nothing.
