Known issues
------------
* On some laptops (for example Librem 15v2), touchpad do not work directly after installation. Reboot the system to fix the issue.
* List of USB devices may contain device identifiers instead of name
* Some PCI devices not working in HVM, sys-net and sys-usb created as PV to workaround this issue
* Installation image lack Whonix templates
* For other known issues take a look at [our tickets](https://github.com/QubesOS/qubes-issues/issues?q=is%3Aopen+is%3Aissue+milestone%3A%22Release+4.0%22+label%3Abug)
It is advised to install updates just after system installation to apply bug fixes for (some of) the above problems.
