You can run "sudo showkey" to monitor what keys are generated. When I press my power button keycode 116 press and release are generated (see keycode # on https://github.com/torvalds/linux/blob/master/include/uapi/linux/input- event-codes.h).
$ sudo showkey kb mode was ?UNKNOWN? [ if you are trying this under X, it might not work since the X server is also reading /dev/console ] press any key (program terminates 10s after last keypress)... keycode 116 press keycode 116 release Similarly, run "acpi_listen" to check whether power button events are generated, ex. $ acpi_listen button/power PBTN 00000080 00000000 button/power LNXPWRBN:00 00000080 00000003 If you are seeing both keycode and acpi power button events when typing "off" or "any", it can be the fault of the system BIOS. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1926527 Title: "Power off" dialog appears when any three keyboard keys are pressed quickly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1926527/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
