Help! qvm-start-gui won't restart properly, so my qube windows are invisible

[floasretch]

A qube window that I was using in full-screen mode died and somehow locked up the gui in dom0 (totally unresponsive to keyboard & mouse input, except that the mouse still moved the pointer), and I had to switch to a text console (ctl-alt-F2) and kill xfce to force it to log out and reset the gui.

That worked, but when I logged back in, all of my qube windows (and all the dom0 windows I had open, including some terminal emulators) momentarily flashed on screen one at a time in rapid succession, then disappeared. Alt-tab doesn't show them.

I can, however, start new dom0 windows, e.g. terminal emulator, qube manager, etc, and they work properly.

xl list shows all my running qubes are still running, and I can access them using xl console, then within them I can use xlsclients and see that everything is still running. But if I try to create a new window, e.g. by running xterm, nothing appears.

https://github.com/QubesOS/qubes-issues/issues/3147 for an unrelated issue has instructions to fix invisible windows:

kill qvm-start-gui process and start it again: qvm-start-gui --all --watch &

But when I do that, all my windows just flash momentarily again, and disappear, same as happened when I logged back in.

Using Qubes 4.0 final release, fully updated.

Please help! How can I get my windows back?

All I'd know to do is reboot- don't know if there's a more elegant way.

Then does Qubes have any way yet to suspend or snapshot VM state, like vmware can do? Most of my qubes won't be a problem to reboot after I reboot the system, but I have one qube in particular with running state that would be a big hassle to re-initialize if I have to reboot the qube.
