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!
|
||
|
|
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`.
