Once in a while, when updating my system after reboot I got a black screen. The problem seems to bee ATI drivers, but it's weird because even TTYs do not work.
For fix it I reboot on recovery mode, uninstall ATI drivers and then install them again and everything it's fine.
However, I'm trying to figure out which update is causing this. Is there any log where I can see which packages were updated the last time I updated the system?
There is a log file located here, /var/log/dpkg.log:
$ head -10 /var/log/dpkg.log

If you use aptitude, you have to look somewhere different:
tail -20 /var/log/aptitude or cat /var/log/aptitude
For older, zipped logs, use this command
zcat /var/log/aptitude.1.gz or zcat /var/log/aptitude.1.gz | tail -20
Just wanted to add to @slm's answer that dpkg.log entries can be interpreted as explained here: https://man7.org/linux/man-pages/man1/dpkg.1.html
In particular, the upgrade lines are interpreted as follows:
YYYY-MM-DD HH:MM:SS action pkg installed-version available-version
So, in
2013-04-03 07:58:02 upgrade libpoppler-glib8 0.18.4-1ubuntu2 0.18.4-1ubuntu3.1,
action = upgrade
pkg = libpoppler-glib8
installed-version = 0.18.4-1ubuntu2
available-version = 0.18.4-1ubuntu3.1
If the dpkg command executed correctly, version 0.18.4-1ubuntu3.1 of libpoppler-glib8 was installed over 0.18.4-1ubuntu2.
