If plymouth specifically changes Num Lock state, this may be a bug in plymouth. However, I don't think it does. I have a theory as to what might be happening: * Each Linux virtual terminal (VT) has an independent keyboard lock/LED state. When a different VT is activated, the driver will apply the lock/LED state for that VT. * If you boot Linux in BIOS mode, the default state of Num Lock is set acccording to what the BIOS says it should be. * If you boot Linux some other way, like UEFI, the default state is unknown and assumed to be off. * plymouth opens and activates a new VT. This applies the default state. Does this system boot using the BIOS or UEFI? If it boots using UEFI, you can test this theory by doing: 1. In the boot menu, edit the kernel command line to remove "splash" and add "break=premount". 2. At the initramfs shell prompt, enter "openvt" to create a new VT. 3. Press Alt-F2 to activate the new VT. Does Num Lock turn off? 4. Press Alt-F1 to activate the first VT. Does Num Lock turn on or off? Ben. -- Ben Hutchings Power corrupts.
