After this morning's updates, I noticed that a bunch of common keyboard
shortcuts didn't work. In gnome-terminal, shift-insert didn't paste
selected text. In thunderbird, 'b' wouldn't move to the previous
message in the folder, but only if the keyboard focus was in the message
body pane. In firefox, the up and down arrow keys moved between links
rather than scrolling the page up and down.
I tried dnf history rollback, but a number of the previous package
versions aren't available, to that failed. Grump: there's no point in
having "history rollback" if packages don't remain available in the
updates tree long enough to roll back to when there are problems.
Then I tried gathering the names of updated packages and using "dnf
downgrade" instead. That caused dnf to offer to install dozens of i686
packages that are not currently installed. I tracked that to
evolution-data-server. Why downgrading that tries to install i686
packages is unfathomable.
Excluding that, the downgrade didn't resolve the problem, but at that
point I noticed that the "orca" process was using a whole lot of CPU
time. I killed it, and at that point keyboard shortcuts were restored.
My guess is that this is related to the python3 package upgrades
somehow, but downgrading them didn't fix the problem. I'm going to try
to find time later to resume troubleshooting this, unless someone beats
me to it.
In the mean time: if you're having problems with keyboard input after
updating, killing the "orca" process will work around the problem until
the root cause has been found and fixed.
