 We recommend using Ubuntu 24.10 and kernel version 6.11 or above, as support for Battle Mage has been backported from kernel version 6.12 to version 6.11, which is included in Ubuntu 24.10, according to the official documentation [here](https://dgpu-docs.intel.com/driver/client/overview.html#installing-client-gpus-on-ubuntu-desktop-24-10). However, since this version of Ubuntu does not include the latest compute and media-related packages, we offer the intel-graphics Personal Package Archive (PPA). The PPA provides early access to newer packages, along with additional tools and features such as EU debugging.
