  • Bizarre behaviour

    From Grimble@2:250/1 to All on Tue Apr 7 16:04:26 2026
    Returning to my office after the Easter break, I found machine Bach had
    frozen - no activity at all. On reboot, there was a message "Cannot
    start mdmonitor.service". Seems mdadm.config suddenly needs a MAILADDR
    entry. Next reboot, freezes on "Checking for new hardware". Gave up but
    left it switched on. Today, added "nomodeset" to grub line, now I get
    "checking for new hardware [ OK ]"
    but it still freezes. The blue "disk activity" LED flashes irregularly
    so there is still something going on.
    But, this is the bizarre bit: I got a confirmation email from Bach at
    04:06 this morning saying the daily dnf run had upgraded 9 packages!
    (Machine Haydn next door to Bach upgraded 10 packages)
    Thoughts:something has upset the video setup so startx can't/won't work?
    Can't rule out fiddle fingers, because my grandson slept there for a
    couple of nights - 17 so he should know better, but still, he's a boy.
    Any ideas anyone please?

    Boot to run level 3 by appending " 3" to the boot time command line options, and check
    "journalctl -b -1 --no-h" to see what messages there are.

    Just fyi, run level 3 is a symlink for multi-user.target.
