After a clean install of Ubuntu 11.10, I have been faced with a crash several times. When I push the computer's power button,it starts to boot as usual, but suddenly it freezes and all I see is a pink screen and a flashing caps lock indicator light. Is there anybody who knows what to do to prevent this from happening?

  • It's a Packard Bell mb87,my graphic card is nvidia geforce 8600 gs and I have installed the system via liveCD.

Can you provide more information. What type of computer ? What hardware (graphics card)? Did the live (desktop) cd work (did you get a graphical desktop) ?? – bodhi.zazen Dec 9 '11 at 0:41

not a problem , that is why you were asked for additional information. – bodhi.zazen Dec 9 '11 at 1:06
Do you have three indicators or just Caps? I've seen all three indicators blinking only on malfunctioning hardware. – int_ua Dec 9 '11 at 2:11
yes i see three of them,but just the caps lock indicator are blinking – Abdurrahman Hodzaoglou Dec 11 '11 at 1:44

This could be due to loading wrong version of Linux kernel image for a version of Ubuntu.

Try manually removing any unwanted Linux kernel images from /boot directory and do 'update-grub' and then re-boot your machine.

In my case, I first installed 32bit-Ubuntu-11.10 which stored Kernel image 3.0.0-14 in /boot directory. Later I installed 64bit-Ubuntu-11.10, which needed kernel image 3.0.0-12. But the grub selected the wrong version of kernel 3.0.0-14, which is configured for 32bit CPU to boot 64-bit Ubuntu 11.10.

As soon as I removed the kernel images of 3.0.0-14 and updated the grub, I got successful boot every time. Just give a try.
