Lenovo T420s graphics problem

Recently its been happening a lot, I am getting this kind of behaviour from my display, sometimes happens when I return the laptop from a sleep, and other times when I hook up an external monitor:

http://ompldr.org/vZmcxMQ

Also, when I play games (say Frozen synapse or Torchlight) the laptop would just make a weird sound, the display gets totally screwed (like with green artifacts) and reboots by itself.

I recorded a video showing this: http://youtu.be/iS705x2F1zU

What can be the cause of this? Where can I check for errors?

thanks for the help

i asked you because could be a problem related to a package update....so check your latest update

reading your errors.log i see many errors but no one related to video card.
post your Xorg.0.log
maybe it is not a video card related problem, i say it because in the log i can see many ATA2 errors

Re: Lenovo T420s graphics problem

Maybe its just that the card is to crappy and literally poops out when it takes heavy load? Hence the system crashes and reboots completely, I doubt there is a log somewhere. Anyways at least the problem is very well documented now big_smile

thanks again for your help!

Re: Lenovo T420s graphics problem

oh, yes, then, with an Intel you have some tools (but i've never used their)

try to heavy load your:

system -> benchmark -> phoronix test suite

Re: Lenovo T420s graphics problem

which benchmarks do you suggest to run? I just installed the phoronix test suite

Re: Lenovo T420s graphics problem

since the problem is video related, i suggest you to run 3D test such as:

lightsmark, nexuiz, unigine

PS: in AUR we have 3 different benchmark based on unigine

Re: Lenovo T420s graphics problem

Same problem here, but I can only confirm the multi monitor problem since I'm not playing games. I think these bugs in the intel driver are known for quite a long time but still not solved.

Re: Lenovo T420s graphics problem

Running nexuiz benchmark via:

phoronix-test-suite benchmark pts/nexuiz

gives me: http://ompldr.org/vZmcxMQ (horizontal lines on right half of the screen, same as my first post)

At first it displays the game running and then poops out.

One fact you should know is that the laptop IS NOT frozen or anything, I can in fact change to another tty (via ctrl+alt+f2 for example), input my username and password, then enter sudo reboot, enter my password and the laptop reboots no problem (I have to do this all blind though).

Re: Lenovo T420s graphics problem

do you get this problem randomly or after a defined time?

Re: Lenovo T420s graphics problem

The longest time I have been able to play is like....5 minutes. It doesn't after a predefined time, but it ALWAYS happens

Re: Lenovo T420s graphics problem

do you have a cpu+graphic chip, in the same package?

Re: Lenovo T420s graphics problem

I have the same CPU.  I only have problems with artifacts with sna.  Haven't tried the above benchmark though...

EDIT: See this thread regarding sna: https://bbs.archlinux.org/viewtopic.php?id=144500

Re: Lenovo T420s graphics problem

i asked it because if it's a thermal problem further the 3D benchmarks, you can try a CPU benchmark which raise your CPU temperature and consequently your graphic card temperature. at this point you can have artifacts
