Did you have it configured to do automatic package updates? > The screen went blank and then came up with "KUBUNTU" glowing slowly ... > It now shows "Lubuntu 18.04" in the middle of the blue screen with > the 4 dots under it being recycled in a different colour. ... > And lo and behold number 2, next day 18.10 showed almost the same > problem!

I wonder if the graphical display manager, e.g. gdm, has a recovery mode where failure of one desktop for the user, say Ubuntu, makes it try the next one, Kubuntu, so the user might eventually get logged in. > What else would be worth trying in the console? `ps axf' shows all processes in a forest. You might see what's taking the time, e.g. an fsck(8). Adding a `u' to that, `auxf', adds columns including %CPU that could show what's busy. `systemctl' will list the state of the system in systemd's eyes. It tends to colour-code unusual states. > I've tried several tests; the only one that showed a hard error was > MemTest86+ when using ALL 4 CORES - it stopped at Test #7 (Block Move > at 4096M-6144M) but with no output, the cpu seemed to have stopped. > With only 1 core all tests were passed. That's the kind of thing to do when all is thought well to give a comparator. :-) -- Cheers, Ralph. -- Next meeting: BEC, Bournemouth, Tuesday, 2019-06-04 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk/ New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
