Hello,
i just managed to upgrade my Lenovo Ideapad Flex 5i (Lillipup) from Chrome OS to Windows 11. Every driver installation went smoothly with no problems. There is one problem regarding my touchpad and touchscreen drivers. Even with the linked Drivers on the Coolstar website for my laptop, i install the drivers and run them but still neither my touchscreen or touchpad is working. I even uninstalled and reinstalled older versions of those drivers without success. In the device Manager is only one active option for mouse and input devices which is my usb logitech mouse that i had to plug in for the installation process. If anyone can help me fixing this issue i would be very grateful.
