I'm having a very similar problem to this too, and I also suspect it's probably something to do with the open source ATI drivers.

When booting from the Live CD (and I've tried the 64-bit and 32-bit versions) I don't even get as far as the screen for installing/trying Ubuntu/Memtest/checking the CD for errors. All I get - which I suspect is probably at the point that I should be seeing that screen is a screen full of black and white horizontal stripes (about ten in total) with a corrupt cursor that appears as a 1-inch square of random-looking pixels.

I suspect it may be the same problem that cause me to (reluctantly) abandon Ubuntu 9.4 and (equally reluctantly) return to Windows. However, I hoped that it would have been fixed by release 10, but alas it seems not.

System: AMD Athlon64 X2 4000+, 4GB RAM with an ATI Radeon HD4800 PCI-E graphics card.

I'd love to go back to Linux but I until the Live CD can deal with the graphics card I have, I'm stuck.

I've checked the CD download (and as mentioned tried both 32 and 64 bit versions) and tried with a CRT, and LCD and both screens at the same time.

I posted the above on the ubuntuforum.org Lucid testing thread and was referred to the same fix as in Sennaista's post above.

But for me... it didn't work. When loading from the CD I initially get the Ubuntu logo, then the ten horizontal lines occupying the bottom one-third of the screen. After about a minute of CD access the screen refreshes and the lines take up the whole screen and the cursor appears.

Pressing Ctrl+Alt+F1 refreshed the screen and the lines took up the bottom third again. Two times out of three nothing further happened until I rebooted, and the other time the screen refreshed once more to the full-screen lines.
