I installed kubuntu 24.04 a couple of weeks ago almost all (except of the camera) worked, battyry cnsumption was rather high and the lid cover was sometimes not reckognized. Two days ago I ha d to install a security patch, since then the microsoft keyboard cover and the touchpad are not rreckognized any more. Any ideas? Do I have to reinstall the whole?
