Comment 0 for bug 2017599

Since installation via upgrade of Kubuntu from 22.10 to 23.04, laptop touchpad input been very laggy. Mouse input by USB has no problem. Hardware is an 81V5 Lenovo V155-15API running Kubuntu 23.04 kernel 6.2.0-20-generic
Problem apparent also when running either Ubuntu (Gnome) 23.04 or Kubuntu 23.04 from USB flash drive. No issue when running 22.10, new owner so untested with 22.04 etc.
