Further issues with Leap 15.5 yesterday morning . . . running 184 packages via
console app . . . GUI "froze" so that I couldn't use the browser while the
upgrades were running, and that process was also very slow. Mouse was
operational. I was about to cancel out of the upgrade, when the last 10 or 15
packages went through. Followed by another long episode with "grub2" before the
cursor returned. But, I couldn't get the Terminal app to "come up" to run
further commands, so I logged into TTY1 . . . .

In the TTY I ran "sudo update-bootloader" . . . also very slow and then
shutdown. On cold boot Leap is first up in grub and several minutes went by
with the black "Leap" screen and the spiral "activity" wheel . . . did not get
to log in screen. I shut it down again. Second cold boot everything went
quickly and now back in Leap GUI to type this out . . . .

Not sure if this is the "aging cpu" that is intermittently causing a slow down
. . . or something in the Leap upgrade that was messing around with the GUI.
There was a new kernel listed in the packages . . . . 

For a rough comparison, today, booted in Deb Sid there were 190 packages to
upgrade . . . machine handled them quickly and I was able to use the GUI and
check browser while the upgrades were going on . . . .
