I use Ubuntu 16.04 LTS on my HP Pavilion laptop.
It worked properly for 10 days after I upgraded Ubuntu 14.04 LTS to Ubuntu 16.04 LTS. But now I have a problem after typing my password in the login window. It doesn't load anything, but it shows only the background theme display picture.
The only information I can see while the system boots is:
dev/sda2:clean,451381/30236672 files.47752164/120944128 blocks
(files and blocks in this output are increasing with every boot)
I don't know what exact issue is this. This happened after installing the OS update.
The guest session works properly. Please help me solve this issue.
