Or not. Removing the --cec-version-1.4 parameter still shows these events, but after a re-boot and re-selection of the proper source on my TV shows that they're no longer coming up with or without the parameter. Further testing showed that by running the older driver and libCEC code, then re-booting into the new kernel (with cec-ctl) shows the messages with or without the flag. In other words, the TV seems to retain some state from the execution of the Pulse8/libCEC code. Is there a way to send a raw message to the television using cec-ctl? Never mind, I found it and after a bunch of messing around, confirmed that I can get the menu keys to be passed from my TV by sending the 0x8e command with a payload of 0x00 to the television: ~/# cec-ctl --custom-command=cmd=0x8e,payload=0x00 --to=0 Thanks for your help with this.
