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.

@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.

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 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
