--- Comment #11 from roger@beardandsandals.co.uk (roger@beardandsandals.co.uk) --- Yes, I take your point. I was speculating on insufficient information. My apologies.
The solution you propose is essentially what I have already been doing. The logging in over a network already works with the unpatched driver. I have not had any luck with keyboard shortcuts. It looks like xwayland/xserver does not know that a problem has occurred and has still got hold of the keyboard and mouse. This is an obscure problem and probably not worth spending much time on. Especially as I no longer seem to be able to reproduce it!
Thank you for your patience.
