HVM sound, webcam, microphone, resolution

[Ian]

Hi all,

I've just started using Qubes and I'm trying to ease transition from my current virtualbox based setup by just importing my virtualbox VMs as HVMs.

I've imported one which is Linux Mint. But there are a few things I haven't been able to get working.

1. Resolution above 1920x1080 (the host is 2560x1440, but xrandr only sees up to 1920x1080.

2. Sound in the HVM. Is it possible to get sound working?

3. Attaching a microphone (built-in) to the HVM

4. Attaching a USB webcam to the HVM

Are any of these possible? Thank you in advance for any help. I've trawled through the docs, and message archives but nothing seems to help.

actualy all of this should work "out of the box"(*).
as in, if you try xrandr or some audio playback in a hvm domain
like sys-net or sys-usb, it should "just work".

you need to attach the mic (device management), and some usb devices
may not work at all with linux usbip ("cable is bad" in dmesg).

your problem is more likely to be lack of xen/qubes support in the
kernel (if you are booting an in-vm kernel) or userland.

try firing up a regular templated appvm instead, and attaching the
mint-image to that as a blockdevice. if you only need "user data"
from the old image, copy things around (or use symlinks).
if you need the "old system", try to chroot into it.

welcome to qubes and good luck.
