Fix Ubuntu 10.04 Lucid Lynx booting problems after upgrade

I upgraded from Karmic Koala to Lucid Lynx today. Quite late. I got some problems. I saw some others also had the same problems, but there were not many websites that have fixes. I was able to find the perfect solution to that.

The problem in my case, exactly was that the upgrade goes on good. Then the computer reboots. But after the splash screen, there is some flashing and the screen goes blank. To fix it, simply shut the computer down directly, start it again, and on the GRUB bootloader screen, press 'E' to edit the Ubuntu option. Then type the following into the seemingly random mangle of codes. Type it after 'quiet splash':


Then, press Ctrl + X and hopefully, Ubuntu must boot up. After it does, your work is not done. The change you made is only a one-time change. To make things permanent, just open a Terminal window and type in:

"echo options i915 modeset=1 | sudo tee /etc/modprobe.d/i915-kms.conf"

And press the return key. Type in the password if it asks for it. Then, after some things are done,  type in one final thing:

"sudo update-initramfs -u"

Close Terminal and reboot. Don't worry, you shouldn't get any more problems. Enjoy the new Ubuntu.
