Comment 14 for bug 1575460

Same problem after fresh install Lubuntu on Dell inspiron 1011
At startup, stuck at:
/dev/sda5: clean, xxx/xxx files, xxx/xxx blocks

What I did, force shut down, then start and choose Advanced Options for Ubuntu, then ubuntu recovery console. From there, I just chose to continue normal boot, and it showed me the login screen and logged me in: but with low resolution screen.
Then I connected the LAN internet cable (not to encounter wifi issues), and I opened a terminal and
# sudo apt-get update
# sudo apt-get install xserver-xorg-video-intel

Then shut down, and started back: problem disappeared.

Thanks for the people who wrote the solutions above, and hope it will be fixed in the future.
