I have been using Ubuntu 14.04 LTS for 2 weeks now. I did browsing using Firefox or Chrome then suddenly screen went blank. I tried to press any keys, but none worked. Thus I needed to press Power key to switch off my laptop.I have been using Dell Latitude D630.

  • Hi, what is your question? What should you do in these cases? Or what triggered it? – sboda Mar 24 '15 at 09:48
  • Hi, I am sorry if my question was not clear. Yes, I would like to know what triggered it? And how to prevent it to happen? – Mico Siahaan Mar 26 '15 at 21:22

You can have a look at the log file in /var/log/syslog here is a detailed description of it: Ubuntu freezes. Which logs can I check out?

but if it occured only once,I would not bother looking it up...
