two questions if you have the answer to just one thats great )

I followed this guide https://forum.qubes-os.org/t/cpu-pinning-alder-lake/17949%C2%A0

now no vms work i get this error "failed to start logical volume “vm-sys-usb-volatile” already exist in volume group “qubes dom0” (vm sys usb volatile is just an example)

also gui is buggy (slow and not appearing where it should be) and clicking doesnt register (not a external mouse) and logging in/out is super long but this happened before cpu pinning and just happens after updating it works fine on fresh install before updating

Hey I see you are trying out Qubes! But I think you got sucked down a bit of a rabbit hole here. CPU pinning is a very deep customization, it is absolutely not necessary, and is a case of the author of the guide wondering "can I do this?" and finding out that yes, there is a way. But I would suggest that you not worry about it, as the difference in performance may not even be noticeable to you.

The best way to approach qubes as a new user is to do almost nothing to modify dom0, and do all your playing around in the qubes.

Also, for in depth tech support like this I would always post to the Qubes forums. Its a niche OS, so posting on a general Linux forum is probably going to not get you a ton of help.

    i did it because i was having problems with it. it was crazy slow and unresponsive (gui doesnt appear when/where its supposed to, clicks dont register (its not an external mouse) only after an update though. without updating (and logging out and back in) it work just fine. i pinned the cpu and that seemed to fix it but then it had problems only after i logged out and back in

    also the forum is a little dead lol

    Have you checked the hardware compatibility list, and the hardware requirements? What are your PC specs? Qubes relies heavily on virtualization and your hardware must support certain features (and those features must be turned on in the BIOS) for good performance.

    So confirm that you have turned on all the recommended hardware features, which should be on BEFORE install, you may need to reinstall if they weren't turned on as I'm not sure what Qubes does at install time if those features are off.
