XFS has proven to be more stable than BTRFS. But still get the ocassional crash. Then I get this same problem where no qubes start after boot/login. I open a terminal and run:
sudo qubesd
And it does it’s thing for a while. Then can start qubes, but no apps will launch - GUI issue? So I have to reboot again. After half a dozen reboots I usually get things to work.
As this has happened on multiple new installs of 4.1 I’m assuming there is some issue there.
This might be related: Crashing qubes virtual machines and "input/output error" - #4 by waliston
But not clear if they’re using 4.1 and their computer isn’t shutting down, just the qubes(VMs) are.
