I have a Ubuntu Certified computer with Ubuntu 12.04 LTS pre-installed on it and ever since I got the computer I have had some really annoying problems with the web browser (Chromium) When ever I would go to www.google.com and enter a search item and press the ENTER key on my keyboard the screen would automatically turn off. (I made sure that I was in the Ubuntu 2D mode) The only thing that I can think of is maybe the computer cannot communicate with the monitor. I have a DELL 17" desktop monitor from maybe 2000 or 2006 not sure.
If anyone has any tips on what I can do to stop this problem please let me know, thank you very much. :-)
