I installed Ubuntu 12/04 64 bit on my desktop using the Nomodeset on boot screen. After the CD finished installing it asked me to restart, I hit restart button, my CD pops out so I take it out and close the DVD drive. When my computer restarted on boot screen it got all purple and warped looking and just sits there like that. Please help, I think it's my gfx card but I don't know what to do to fix this.
You should try adding nomodeset to the default boot again. After the BIOS screen finishes on your computer press
If that works you'll want to make it permanent in which case you have to edit the default grub file:
