My ubuntu 12.04 distro often freezes when for example watching a youtube video.

My system is a 15,6 inch BTO VBOOK 15CL17 FULL HD IPS with a Intel HD Graphics 4600.

lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphic

After a crash my dmesg.log looks like this: http://paste.ubuntu.com/7010739/

and my lshw output is as follows: http://paste.ubuntu.com/7010769/

How can I test if my graphics driver is causing this problem?

    This is neither a duplicate of "What should I do when Ubuntu freezes" nor is off-topic with the information provided by the OP. It asks how to test the graphics drivers to see if it is involved in the freezing problem. – Luis Alvarado Mar 01 '14 at 20:42

I would first recommend installing sensord to test the temperature of various hardware devices (CPU for example):

sudo apt-get install sensord

After that simply run sensors to get a reading. It should look something like this:

If you can get to the desktop somehow (Or change to another desktop or even run an LiveCD or LiveUSB image to test the hardware) you can install psensors

or from the Panel

enter image description here

You can also check the Hard Drive temperature with hddtemp just in case it is also affecting the freezing problem:

Lastly there is another GUI app called i-nex which is first added to Ubuntu via a PPA:

 sudo add-apt-repository nex-development-team/stable
 sudo apt-get update
 sudo apt-get install i-nex

Then simply run i-nex:

As you can see there are a couple of ways of checking the integrated video card, PCIe video card of even the CPU and HDD for temperature readings.

I would also recommend checking in your laptop/motherboard site if they have an updated firmware. In my case I was having a similar problem when using 3D with the HD card until I updated the firmware.

Another upgrade I recommend is to either apply the Xorg Edgers PPA or the Intel Graphics installer Update:

Intel Graphics Installer - https://01.org/linuxgraphics/ - Simply download the appropriate driver package and install. You can also find the changelog in there.

Xorg Edgers PPA - Run the following 3 lines and then reboot to see the enhancements:

sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get upgrade

That should leave you with an updated Mesa, Intel drivers and a couple of more things as shown in the Xorg PPA site.

So you have various alternatives to check and update the system.

  • Thanks a million, The problem seemed to be solved by the Xorg Edgers PPA upgrade. However I could not add the nex-development-team/stable repository. At the moment that is not required since the problem seemed to be solved. If it haunts me again I will try the other tips. Also for the hardware temperatures I obtain values between 14 and 41 degrees for different components. But I am not sure what values would be alarming here. – MaxBaeten Mar 03 '14 at 11:13
