New Qubes OS user, installed latest 4.3 on new build, then installed fedora-42 template, switched all qubes to it and uninstalled original fedora-xfce template. All is running nicely. Next I did the following: Updated dom0 and created sys-usb with sudo qubesctl state.sls qvm.usb-keyboard Ensured…

Make sure your Qubes Global Config USB Devices settings look like this: [image]

Mine does not look like yours. [img1] When I attempted to start the sys-usb qube I got a popup: [Dom0] Error starting Qube! Cannot connect to qrexec agent for 60 seconds, see /var/log/xen/console/guest-sys-usb.log for details I looked into this log, the last latest line reads: [ 0.479089] …

Can you post a little more of /var/log/xen/console/guest-sys-usb.log? But also, global config not finding USB qube suggests something is wrong with device assignments to sys-usb. And finally, which kernel sys-usb uses?

Not sure if related or not, but I had an adjacent issue after a fresh 4.3 install with USB devices: [image] Qubes OS 4.3.0 has been released! I did notice that in Qubes Global Config, under USB Devices, it spammed me with errors. I noticed that the drop downs were not selected to anything so I j…

guest-sys-usb.log (108 KB) I am using kernel 6.17.9-1.fc41 I originally installed with 6.12.59.1.fc41 fedora-xcfe using sys-usb from installer and had no issues with sys-usb and booting but audio did not work. Audio now works with my current setup but sys-usb issue of course.

Please see pic I posted of that screen, I could not change anything there.

Do you use audio via sys-usb? If not, it seems the audio is related to dom0 kernel version, which can be different than sys-usb one. You can change sys-usb kernel version in its settings (advanced tab). As for the crash, can you share more details about the hardware? Specifically: CPU model sudo …

I didn’t use audio via sys-usb specifically and didn’t know I had to; do I? (remember, I’m new!) I just tried now and audio now not working again, system doesn’t see my earbuds when I plug them in there is and no sound even though Audio mixer shows stream activity. This definitely worked before I a…

OK, two steps forward, one step back. Deleted sys-usb Changed default kernel back to 6.12.59.1.fc.41 Ran sudo qubesctl state.sls qvm.usb-keyboard sys-usb now starting with keyboard enabled for luks and user login I then followed advice from posts in this thread to set keyboard and mouse to ‘alway…
