Well my problem is taht after installing ubuntu, i restart my computer, and select ubuntu from the boot screen, the screen goes a purple color for a fraction of second and then it changes to black with a white blinking underscore on the top left, i have an HP notebook so i tried using usb with no results, then i tried the windows one, installed and reinstalled like 3 times, help.

I had a similar problem but instead of black, my screen was purple. I upgraded from 11.04 to 12.04 and the upgrade went smoothly (no errors/no-warnings). After the upgrade and re-boot the X-server was un-responsive. No mouse/no keyboard. ctl-alt-Fx did not work the keyboard was totally dead, caps-lock did not toggle the LED, but I could ssh from another machine. I suspected it could be my non standard ATI graphics driver. After a lot of searching I found a new AT installer but I had to uninstall the old one first.
- Downloaded the newest AMD installer from http://linux.softpedia.com/progDownload/ATI-Radeon-Linux-Display-Drivers-Download-6719.html
- Uninstalled the old fglrx driver by
sudo apt-get remove fglrx
sudo ./amd-driver-installer-12-6-x86.x86_64.run
After step 2 I could restart my PC and things were better. The mouse moved and I could type. So I tried to install the latest AMD ATI driver and after a reboot it worked.
