This is a long-standing issue for some, resolved for some but not for
others at different times. See
https://github.com/QubesOS/qubes-issues/issues/4042

The situation has improved for me by getting kernel 4.19.43-1 from
qubes-dom0-security-testing. You could try the new kernel. (But note
that our problems might be a bit different, I never had a qrexec problem
when restarting sys-usb after resume.)

If you need to automate restarting of sys-usb because you can't avoid
this problem, you can add commands in
/usr/lib64/pm-utils/sleep.d/52qubes-pause-vms for suspend and resume,
e.g., qvm-shutdown sys-usb and qvm-start sys-usb. You might need to
qvm-kill sys-usb before suspend to get this to work reliably.

[qubes-users] Lenovo T480/T480s anyone got power management working properly?

[mmoris]

Hello,

I'm struggling to get my T480s working on resume as it displays a blank screen 
that doesn't allow me to do anything.
All problematic modules are already part of the suspend blacklist:

ehci_pci
xhci_pci
iwldvm
iwlmvm

Nonetheless the resume only works when I shutdown the sys-usb before the 
suspend, which is a bit painful to do on every suspend.
Power management also doesn't work, when I press the power off button nothing 
happens nor the laptop enters the suspend state.
The battery also get hot very quickly and drains very fast it seems its not 
optimized.

Did anyone managed to fix these issues with the T480s or the T480?

Any recommendations are really appreciate.

Thank you!

Re: [qubes-users] Are used laptops safe to use?

Format the hard drive and you'll wipe most third party malware. The odds
of you finding a used laptop with one of the exceptions that survives a
format is slim. There is also a chance a new laptop could come
compromised. Up to you to determine what is "safe" for you.

I've heard of people getting USB controller passthrough to Windows
working on 3.2+, but 3.1 is before my time...
