The issue I am experiencing with 4.0 on my new hardware is the following: once I open the lid and resume qubes after suspension, I cannot issue any command/trackpad/mouse whatever.
Do you have any ideas on how to debug this? I have found on this ML some related issues, but since they aren't really recent, I don't know if they are still relevant for my case. For example, in https://groups.google.com/forum/#!topic/qubes-users/QrG7uUZsSZY the last poster seems to have my same issue and the suggested fix did't help.
Thanks.
Fully working T480 with Qubes 4.0 writing here. I found I needed to remove the assignement of one of the USB controllers from sys-usb. See earlier HCL. My debug strategy was to shutdown all service VMs and check if suspend works , then narrow the issue.
Note that on my machine it takes about 5secs to become responsive after unsuspend.
After installing the latest Updates and Kernel in dom0 today, the issue is gone for me. Maybe it'll help with your issue too.
I removed the pci device which is the USB controller:
qvm-pci detach sys-usb dom0:3c_00.0
Any ideas?
