I have X1 Carbon Touch with Intel HD Graphics 4000 integrated and with Ubuntu 13.10 x64 installed. A bunch of random bars and colors sometimes appears on screen. Does anyone have the same problem? What cause this and are there any solutions to this issue?
I am sorry to hear you are having these problems. I want you to try the latest driver we have for your Graphics controller. It can be downloaded the following link:
IN case the driver above is not working, can you please post your dxdiag report here? Also is very important to know what connections you are using.
