In this article, we will discuss the process of upgrading Kubuntu from version 24.04 to 24.10, focusing on the switch from the X11 desktop environment to Wayland and the preference for a 4k monitor resolution of 2560x1440.
Upgrading Kubuntu
Before starting the upgrade process, ensure that your system is up-to-date. You can do this by running the following command:
sudo apt update && sudo apt upgrade -y
Switching to Wayland
Kubuntu 24.10 has switched the default desktop environment from X11 to Wayland. To check if Wayland is currently being used, run the following command:
echo $XDG_SESSION_TYPE
If the output is x11, you are currently using X11. To switch to Wayland, run the following command:
startplasma-x11 --replace
Configuring 4k Monitor
To set the preferred resolution for your 4k monitor, follow these steps:
- Open System Settings.
- Navigate to Display and Monitor.

- Click Apply and then OK.
Upgrading VirtualBox

- Download the appropriate VB package for your architecture from the VirtualBox downloads page.
- Install the downloaded package using the following command:
sudo dpkg -i /path/to/VirtualBox_*.deb
- After installing, run the following command to set the proper permissions:
sudo usermod -aG vboxusers $USER
- Log out and log back in for the changes to take effect.
