@Pierlink_Cloud This forum is for discussions and help on Ubuntu Touch proper, so your post is bordering on being off topic. I have moved it to the off-topic category for now. Let's see if anyone can help you transition from LXDE (or is it LXQt now) to Lomiri on what was originally a Lubuntu installation to your laptop. I will say though, that the recommended way of installing Lomiri on Ubuntu is to start out with Ubuntu Server 24.04 and install Lomiri from the PPA.
