I had tried the beta version of Lucid Lynx few weeks back but it didn’t boot, it gave me blank screen with no cursor everytime I tried to boot up. Even the menu didn’t show. I thought there must be a bug since its beta. When final version released day before yesterday, I quickly downloaded and burned a CD only to find the same problem while booting. I couldn’t even see the menu. The problem is thought to be associated with ATI cards… mine is ATI x1250.
After doing some searches on google and some experimenting I found a solution to this problem. Adding a nomodeset parameter while booting solves the problem. For my even the menu wasn’t appearing, but pressing F6 made it appear for me.
As soon as you see this screen press F6 to bring the language selection menu. Select appropriate language and press enter. Now, you’ll see the boot menu. Press F6 to bring another menu to select kernel parameters and select nomodeset from the menu. Here’s what it would look like:
Now, press Esc and press enter to boot. If you’ve done everything right, it’ll boot right into the desktop or ubiquity-installer… whatever you’ve chosen.
However, after installation you may face this problem again. To solve that edit the file /etc/default/grub.
Find the line:
and change it to:
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash nomodeset”
Save the file.
After this execute sudo update-grub2 in terminal to make changes to grub.cfg automatically
