I recovered an old laptop (HP compaq nx5000). It worked with Ubuntu Server 8.04 very good a lot years ago. I'm trying install Ubuntu Desktop 12.04 & 10.04, but the laptop freezes on the first 15 minutes.

I reinstalled Windows XP and the laptop works perfect, without freezes. I think is a kernel issue. I read this great documentation and this, but I'm little lost with it. Which parameter could be the issue?

"Freezes" is too vague a problem to give you a definitive answer...more details, please? – izx May 17 '12 at 7:32
@izx: Mouse, Caps lock, keyboard... all is freezed :P I instaled a lot of computers with Ubuntu, I think is some kernel issue :( – costales May 17 '12 at 7:59
How much RAM have you got? The memory needed by Ubuntu has crept up over time... The HP Compaq nx5000 has, I believe, Intel video. Look at… – arochester May 17 '12 at 8:06
If the laptop only has 256Mb (1) Try to increase the amount of RAM if you can: or (2) Try Lubuntu or Xubuntu instead of Ubuntu. They are far less demanding of memory. Are you using the Desktop disk (LiveCD) or the Alternate disk? The Desktop disk uses more memory than you have, to install. The Alternate disk is a straight install and is a better choice for you. – arochester May 17 '12 at 9:42

look in /etc/default/grub

change the line



  • GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"

and now just update grub with sudo update-grub.

Just one note: In this laptop you must install lubuntu 12.04, not ubuntu desktop 12.04. – costales May 18 '12 at 10:41
