Hello, ioctl's KDGETLED or KDGKBLED do always return 0 on my ThinkPad X230 (Tested with a small program). The keyboard of this laptop does not have an LED. Maybe that is the issue? If it would still possible to get the caps lock state somehow it would be great. This is used for example in plymouth: https://gitlab.freedesktop.org/plymouth/plymouth/-/merge_requests/67?commit_id=7f49ef3fe655b1ac94ddafd5a4ca325b7b070d7b Caps Lock as such is working. Thanks
