View Full Version : [ubuntu] Video card artefacts

September 5th, 2011, 03:44 PM
Hello. I have notebook Asus K70IO with Ubuntu 11.04.
Sometimes, video bug is appears - whole screen fills with different color lines, and it moves. To restore normal screen, you need to close/open LID, or move on virtual terminal and back to X server.
I've made video with this bug: http://www.youtube.com/watch?v=30Mzce0ZvRs.
The bug was on Ubuntu 10.04, I don't know, if that bug exists on Windows ( maybe hardware problem ). Before Ubuntu, there was Windows7 near one year on notebook, and i have't noticed this bug.

My Videocard is Nvidia GeForce 120M, Nvidia poprietary driver 270.41.19 ( from PPA with CUDA ). The bug exists on default poprietary drivers.
Open-source driver even doesn't work on this notebook

I've forgot to mention, bug appears randomly, but likely when I watching video fullscreen, or working in VirtualBox in photoshop.
Bug appears several times per hour

I've tried to make screenshot and connect via VNC when bug is appeared, and there isn't artefacts.

Anyone? Can this problem be hardware? What do I can do else to determine problem?
