Why does Ubuntu gets stuck on the loading screen?
- by mohit
I've been experiencing many problem lately since I fresh installed Ubuntu 12.04 LTS
on my SONY VAIO VPCEH with Windows 7 previously installed.
Sometimes when I try to boot Ubuntu, it gets stuck at loading screen.
There seems to be some problem with driver (as far I can judge).
Following is the log generated, when I press Esc during the boot (before the
problem occurs):
...
* Stopping System V initialization compatibility [ok]
* Starting System V runlevel compatibility [ok]
* Starting crash report submission daemon [ok]
* Starting automatic crash report generation [ok]
...
...
* Starting LightDM Display Manager [ok]
Nothing works after that, no Esc, etc, except restart.
Also I've observed the following:
Inactivity of Hard-drive (Led doesn't glows).
Flashing, or blinking, of Caps-lock and Scroll-lock
On restart, Ubuntu seem to load successfully. However, the loading
screen has somewhat basic graphics.
This problem started after I installed Additional drivers:
NVIDIA accelerated graphics driver
Also, most of the times Ubuntu loads without any problem. However, it
is annoying to restart everytime it fails.
So my question is:
Why this happens and what is the solution?
