I am not able to log in to Ubuntu. When I start my laptop and select Ubuntu, the screen with the Ubuntu logo and progress bar dots is shown. I wait for some time but it doesn't show me the login screen. I have tried to restart it but the same problem occurs. I am new to Ubuntu.

Please do the following so you can show us more info about what is not working. When the ubuntu option appears in the menu press E for Edit. Go to the line that starts with LINUX and press E again. Go to the end of the line which should say QUIET SPLASH. Remove the words QUIET SPLASH and press enter. Then press B for Boot. What you did back there was remove the splash logo and tell linux to show you what linux is doing while it boots. It will tell you everything but if it is getting stuck somewhere it will say it normally in the last line. Show us what is the last line or where it gets stuck. –  Luis Alvarado Dec 17 '10 at 7:46

Try this:

sudo gedit /etc/default/grub

Find the line: LINUX_CMDLINE_DEFAULT and add this between the "": quiet nosplash nohz=off

Then:

sudo update-grub

Do all this in a terminal window, of course, and then reboot.

he can't login. He cannot run anything if he can't login or boot. –  Thomas W. Aug 3 '11 at 15:41
    
I don't think a vote down is deserved...he can edit GRUB at boot time by pressing "A" before the boot screen and then selecting the current kernel and pressing "E" and finally "F10". I've done it both ways (GUI and boot). –  rdrgrtz Aug 3 '11 at 20:04
