Google searches don't yield much except a few mentions of similar problems - mouse becomes unresponsive, then keyboard and the only way out is a hard reset. There seems to be some thinking that it is GTK2/3 theme related and so, yesterday I tried a vanilla installation using the TraditionalOk theme (reported as being stable), without any other changes. Went fine for a few hours then, without warning, crashed again. Same symptoms as previously with mouse becoming less and less responsive, then keyboard not responding and all the while the HDD light being constantly on. I just walked away in disgust and did a hard reset this morning.
Upon restarting all my application launcher icons in the top panel had crowded across the the left hand side and reversed order. Same as what has happened previously and there have been some mentions of this in Google search results.
Problem is that I haven't really found a solution since I, and apparently others, don't really know the cause. There seems to be nothing specific that triggers this - on previous tries it has run for days without a problem and then crashed again 30 minutes or less after recovery. Seems to be completely random.
I'm running MATE 1.16 now but have tried 1.18 before, without any improvement. I've seen a mention that 1.20 may have fixed it (fully GTK3) but can't find any confirmation.
Following is an extract from syslog, starting about 15 minutes before the last crash which happened at 21.02, and then the log continues for some time after that. There are another 7 hours of log, but nothing any different.
