I have a 3 year old Dell Inspiron 1520 laptop and I would really like to put Ubuntu 10.04 Desktop (AMD64) on it, but my attempts have failed.
This laptop currently boots either Vista (32-bit) or Kubuntu 8.10 (AMD64). I have had Ubuntu of a similar vintage on it in the past. I want to keep this Kubuntu installation for the time being (because I have all my hardware working with it, including the internal wifi) and I want to install Ubuntu 10.04 on the empty 10GB partition that used to hold an old Ubuntu.
I have downloaded the iso image and burned a CD. I have used this CD to install on a desktop machine, and have also booted from and run this CD on a Dell Inspiron 1521 as a Live CD, so I don’t think there’s anything wrong with the CD. If I boot my laptop from the hard disk’s Kubuntu 8.10 installation, then I can browse the CD without any errors, so I don’t think there’s an incompatibility issue between my optical drive and the CD.
However, if I boot from the Ubuntu 10.04 CD, the initial almost blank screen with a logo at bottom centre of the screen is displayed, then after somewhat less than a minute, a screenful of vertical lines of multiple colours is shown, each line being between 1 and 5 pixels wide (estimated - photo available if it helps). This screen remains for a while until the CD stops being accessed, then eventually I give up and reboot. Booting from another CD containing 10.04 i386 Desktop has similar results.
Under Kubuntu 8.10, lspci shows my graphics card as:
01:05.0 VGA compatible controller: ATI Technologies Inc RS482 [Radeon Xpress 200M]
It works fine under Kubuntu 8.10 at 1280x800 (60.0 Hz).
Any clues or suggestions for progress?
