Kernel and performance

Check the kernel, processor and task scheduling in Settings.

Check the system

Open Settings → Kernel and performance. The page shows the running kernel, detected processor level, optimized package sources and configured graphics drivers. You can keep the defaults for everyday use.

Choose another kernel

The page lists installed and available kernels. You can install or remove a variant there. The choices include an everyday kernel and a long-term LTS kernel. Read the confirmation before making a change. A new kernel is used after a restart. If the catalog is missing, run a full system update first.

Task scheduling

If your system supports sched-ext, the page shows the current scheduler. You can apply an available option, enable it at startup or stop it. If support is missing, the choice stays disabled.
