well… after an update quite a while ago my lirc and lcdproc stopped working. starting lirc on the default ubuntu install would always result in:
unable to load LIRC kernel modules. Verify your selected kernel modules in /etc/lirc/hardware.conf |
so trying to add the modules manually would tell me a bit more:
root@augustiner:~$ modprobe lirc_imon FATAL: Error inserting lirc_imon (/lib/modules/2.6.31-21-generic/updates/dkms/lirc_imon.ko): Unknown symbol in module, or unknown parameter (see dmesg) root@augustiner:~$ dmesg | grep lirc_imon | tail -n1 [ 420.742877] lirc_imon: Unknown parameter `islcd' |
i noticed a line in the options that was wrong and removed it:
options lirc_imon islcd=0 |
lirc was back up and running but not my LCD screen. the logs showed:
[ 492.637968] lirc_imon: lcd_write: invalid payload size: 32 (expecting 8) [ 492.762951] lirc_imon: lcd_write: invalid payload size: 32 (expecting 8) [ 492.887947] lirc_imon: lcd_write: invalid payload size: 32 (expecting 8) [ 493.012940] lirc_imon: lcd_write: invalid payload size: 32 (expecting 8) [ 493.137946] lirc_imon: lcd_write: invalid payload size: 32 (expecting 8) [ 493.262958] lirc_imon: lcd_write: invalid payload size: 32 (expecting 8) [ 493.387957] lirc_imon: lcd_write: invalid payload size: 32 (expecting 8) ... |
some further googling and i found out that the options line has changed from release to release. to get it back working use:
options lirc_imon display_type=1 |
to get the write type just look into lirc_imon.c
enum { IMON_DISPLAY_TYPE_AUTO, IMON_DISPLAY_TYPE_VFD, IMON_DISPLAY_TYPE_LCD, IMON_DISPLAY_TYPE_NONE, }; |
