### My keyboard layout settings are not behaving correctly. What should I do?
|
||||
|
||||
The best approach is to choose the right keyboard layout during the installation process.
|
||||
But if you want to change things afterwards, you can try this workaround.
|
||||
|
||||
Assuming XFCE desktop: in `Q` → `System Tools` → `Keyboard` → `Layout`, leave the checkbox "`Use system defaults`" checked. Do not customize the keyboard layout here.
|
||||
|
||||
Set the system-wide layout and options for `xorg` with the `localectl` command in `dom0`. You can use `localectl --help` as a starting point.
|
||||
|
||||
Example: `localectl set-x11-keymap us dell ,qwerty compose:caps`.
|
||||
|
||||
This generates the appropriate configuration in `/etc/X11/xorg.conf.d/00-keyboard.conf`.
|
||||
This file is auto-generated.
|
||||
Do not edit it by hand, unless you know what you are doing.
|
||||
|
||||
Restarting `xorg` is required.
|
||||
The most straightforward way is to reboot the system.

Troubleshooting newer hardware
|
||||
==============================
|
||||
|
||||
By default, the kernel that is installed in dom0 comes from the `kernel` package, which is an older Linux LTS kernel.
|
||||
For most cases this works fine since the Linux kernel developers backport fixes to this kernel, but for some newer hardware, you may run into issues.
|
||||
For example, the audio might not work if the sound card is too new for the LTS kernel.
|
||||
To fix this, you can try the `kernel-latest` package -- though be aware that it's less tested!
|
||||
(See [here][dom0-kernel-upgrade] for more information about upgrading kernels in dom0.)
|
||||
In dom0:
|
||||
|
||||
~~~
|
||||
sudo qubes-dom0-update kernel-latest
|
||||
~~~
|
||||
|
||||
Reboot when it's done installing.
|
||||
You can double-check that the boot used the newer kernel with `uname -r`, which prints the version of the currently-running kernel.
|
||||
Compare this with the output of `rpm -q kernel`.
|
||||
If the start of `uname -r` matches one of the versions printed by `rpm`, then you're still using the Linux LTS kernel, and you'll probably need to manually fix your boot settings.
|
||||
If `uname -r` reports a higher version number, then you've successfully booted with the kernel shipped by `kernel-latest`.

If this solves the issue, it confirms the PCI card is incompatible with Qubes.
|
||||
In this case, you may want to consider replacing it with a network card of a different brand.

Broadcom cards are notoriously problematic with Qubes.

## "Unsupported Hardware Detected" error ##
|
||||
|
||||
During Qubes installation, you may come across the error message which reads "Unsupported Hardware Detected.
|
||||
Missing features: IOMMU/VT-d/AMD-Vi, Interrupt Remapping. Without these features, Qubes OS will not function normally".
|
||||
|
||||
This error message indicates that IOMMU-virtualization hasn’t been activated in the BIOS.
|
||||
Return to the [hardware requirements][hardware-reqs] section to learn how to activate it.
|
||||
If the setting is not configured correctly, it means that your hardware won’t be able to leverage some Qubes security features, such as a strict isolation of the networking and USB hardware.
|
||||
|
||||
In Qubes 4.0, the default installation won't function properly without IOMMU, as default sys-net and sys-usb qubes require IOMMU. It is possible to configure them to reduce isolation and not use IOMMU by changing virtualization mode of these two VMs to "PV".
|
||||
|
||||
In Qubes 4.1, IOMMU is strictly required, even when the virtualization mode of a VM is changed to "PV"; it is not possible to use Qubes on a system without IOMMU.
