zypper-what packages were updated ?

Is there a way to trace what packages were updated during the last zypper update ?
I ran an update this morning, but did not see what was changed, and now my laptop won’t run the display manager.
Hopefully i can revert to an older version package that’s messed up…

Thank you

Have a look at the file /var/log/zypp/history.

Or to get a list of all packages sorted by the install date:

rpm -qa --last

Since that list will be quite long, you may want to redirect it to a file or pipe it to less:

rpm -qa --last | less

Worked. Thank you !!
