Thanks for the response.
Firstly the keyboard is okay and has been swapped with my other LL4.8 system, which has been working with zero errors 24/7 for several years, just in case, but with the same results. As I say the two systems are very similar, including the keyboard.
The use of the xev has proved very informative on the way the system operates, but it has also emphasised that the actual problem is very elusive. I have spent quite a while trying to find a combination that is repeatable, but when all is said and done, this is the summary.
The Whisker Menu popping up seems to be the catalyst for any further cursor delay behaviour.
But as I say, it’s elusive, and tends to happen when the system is being used, with various windows active, configuration work and such like going on.
When using xev with the cursor on the desktop area, and just pressing keys, you get very responsive KeyPress and KeyRelease event results from the terminal. And with the cursor in the Event Tester Window, MotionNotification events are also very responsive. I even enlarged the Event Tester Window to achieve large movements, but the only time the Whisker Menu popped up, during the xev session was when I started moving the cursor in circles on the desktop, on the right hand side away from all the windows.
In fact the most repeatable, or at least the most frequent occurrence was when just a normal LL Terminal was opened, with no other programs running on the desktop, and again just doing rapid circles with the cursor for a few minutes. This caused the Whisker Menu to pop up, and just pressing escape closed it down. I was able to do this twice within about a 5 minutes period.
After working with an LL4.8 that has been so reliable, it has been a surprise to see anything LL be less than almost perfect.
Could it be some buffer overflow problem somewhere, or suchlike.
BTW I still don’t know how to persistently set the system keyboard layout to UK or gb, as the /etc/default/keyboard didn’t do it, nor did the installation setup. So where is it defined?
It sounds to me like this is software rather than hardware, especially with the cursor lag, when it happens. But my confidence has been knocked somewhat, and I can’t really move forward with all the usual configurations if there’s something unreliable in the works somewhere.
I’m even tempted to move back to LL4.8, if it wasn’t for the fact that support for that version won’t be for much longer.

I know you believe you understand what you think I said. But I'm not sure you realise that what you heard is not what I meant.
