After experimenting with external monitor, namely, switching between xfce vm and native chromebook desktop, xfce does now work as before (no mouse pointer, no window handlers) with external monitor disconnected. Is it 'unknown mode 1920x1908' warning I shall pay attention to?

You might be able to fix it by going to the xfce display settings and choosing a proper resolution. Otherwise, you can always delete the chroot and create a new one.
