Friday I installed upgrades, then shutdown my computer for the week-end. This morning (monday) my Ubuntu hangs at boot. The "loading dots" screen become a black screen, then nothing happens.
If I press the power switch, the system seems to unload correctly, and stops.
Some times it says that it has issues loading the swap so I tried this solution : Cryptswap boot error - can't mount? It didn't work.
Then I tried to log as root, remount / with rw mount -o remount /, activate my network by modifying /etc/network/interfaces, and update packages apt-get update
apt-get dist-upgrade
apt-get upgrade
It does not helped.
I'm newbie to Ubuntu so I'm not sure where to find boot error messages (if they exist), I looked in /var/log/boot.log and /var/log/bootstrap.log but did not find any error clearly written.
This is my work computer, so I'd like to resolv the issue asap. Is it possible to force a full packages reinstall ? Or a system reinstall while keeping my personal files and configuration ?
edit1: According to Ubuntu boot hangs, I tried to set gdm as the default X. This changed nothing.
Thanks,
