I just bought this notebook and I've already installed in a new partition Ubuntu 12.04 LTS with 6GB of swap memory.

UPDATE2:

This is the laptop configuration: http://h10025.www1.hp.com/ewfrf/wc/document?cc=it&lc=it&dlc=it&tmp_geoLoc=true&docname=c03397517

Sometimes (without any special conditions) Ubuntu freezes. My mouse is blocked, the UI is blocked, Alt+F1 to kill something or to restart is blocked, I can't really do anything...

I've also tried and it freezes with:

  • Ubuntu 3D
  • Ubuntu 2D
  • GNOME Shell

and it freezes both with low and high load.

I can only press the power button (physically) and restart my laptop (and this is not the correct way to do things). I'm using this laptop for work, so I need a stable OS without this freeze.

Someone knows how to solve this problem?

UPDATE:

I just installed the proprietary driver from ATI, but it crashes anyway. This morning I started the laptop, I enabled wireless, opened Dropbox and Chrome -> freeze.

When it freezes I cannot:

  • Do Ctrl+Alt+F1 to get console access
  • Alt+F2 + r to reload session
  • Alt+Print Screen + RESUB to restart

It is totally frozen.

    I'd suggest posting the system logs (/var/log/messages, /var/log/kern.log, /var/log/Xorg.0.log) using paste. – January Sep 21 '12 at 14:40

    @fossfreedom not really, since he wants to solve a particular problem with a particular machine. Maybe someone who has the same laptop will see the question and posts a specific reply. – January Sep 21 '12 at 14:43
  • @January updated with logs, hope it helps – StErMi Sep 22 '12 at 09:38
  • Have you done any kernel updates recently ? Try different kernel version from "Previous Linux versions" in GRUB menu. – dixoncx Sep 22 '12 at 19:14

@StErMi, the errors below can be related to your problem.

[FIRMWARE BUG] ACPI(PEGP) defines _DOD but not _DOS

[Firmware Bug]: Invalid critical threshold (0)

drm:intel_dsm_platform_mux_info] *ERROR* MUX INFO call failed

According to this, using the acpi_backlight=vendor option will solve first bug. If this does not work, you can try the acpi=noirq option.

For the second bug, it is recommended to make a BIOS update and you can see that BIOS update solved the problem.

For the third one, one workaround is to use the pci=noapci option, but if you use this option you will not be able to use the ATI graphics card.

I know these will not permanently solve your problem but at least there is hope that one of the workarounds could provide a usable Ubuntu for you.

To use the options that are mentioned here, look at this link.

  • if those changes will fix my freeze, how can I share my solution in order to set by default those options in fresh installations? Anyway I will try to do as you said and I will update (and change as correct answer) in a few days of testing. Also, from Windows I launched HP Help that automatically update bios. Is it really updating bios or have I to do it manually? – StErMi Sep 22 '12 at 11:52
  • As I said I'm using Ubuntu only to develop, so I don't need to have the ATI enabled, I think that integrated VGA can handle Unity3D animations right? So I can enable pci=noapc, am I correct? – StErMi Sep 22 '12 at 12:10
  • acpi_backlight=vendor has not worked (it freezed again). Now I will try to use acpi=noirq. Have I to use both or only the latest? – StErMi Sep 24 '12 at 10:23
  • also acpi=noirq wont solve the problem, it has just freezed :( now I'll try to add pci=noapci to grub config – StErMi Sep 26 '12 at 08:23
  • Sorry, all those options have not solved my problem :( – StErMi Sep 28 '12 at 13:00
  • Sorry for tha late answer and what I offer to "solve" the issue didn't solve it. I will search a suitable workaround. – numand Nov 12 '12 at 15:17
  • I already solved my issue, please look at my accepted answer :) – StErMi Nov 13 '12 at 12:06
  • I am glad you find a solution:) – numand Nov 16 '13 at 18:34

I had a random freeze problem with my new Lenovo T430s as well (i7-3520M). It was between once-a-week and 3-times-a-day.

Somewhere on the Internet I've found indications that this might be an Ivy Bridge graphics causing the freeze.

Then I updated to 12.10 alpha and problem has vanished.

Could it be the same problem despite you are using AMD/ATI graphic card?

  • I thought so, I started install of 12.10 and it freezed, so everything was broken. I tried to install from USBStick a fresh 12.10 but it wont start, so I'm still stuck on 12.04 with these freezes :( I will wait for official release of 12.10 on end of October – StErMi Sep 28 '12 at 13:01

I think that the solution is to upgrade the current kernel to version 3.x this seems to have solved my problem. In this Article I understand that I've the same problem of that user (Ivy Bridge bug).

Steps:

sudo add-apt-repository ppa:upubuntu-com/kernel
sudo apt-get update

For 32bit users

sudo apt-get install linux-kernel

For 64bit users

sudo apt-get install linux-kernel-64
